Statins may be temporarily withheld or discontinued in patients with S/S of myopathy or potential for renal injury, including renal failure, secondary to rhabdomyolysis. To minimize the effect on blood levels, administer sirolimus 4 hours after cyclosporine dose. Other side effects include acne, convulsions, cramps, diarrhea, encephalopathy, glomerular capillary thrombosis, headache, hepatotoxicity, hyperkalemia, hyperuricemia, hypomagnesemia, infection, leukopenia, lymphoma, microangiopathic hemolytic anemia, nausea and vomiting, paresthesia, skin rash, and thrombocytopenia. Treat hypersensitivity as indicated; may require oxygen, epinephrine (Adrenalin), antihistamines. Acute myelocytic leukemia or erythroleukemia in adult and pediatric patients: Manufacturer lists a dose of 100 mg/M2/24 hr as a continuous infusion or 200 mg/M2/day continuous infusion (as 100 mg/M2 over 12 hours every 12 hours) for 7 days. Through various chemical processes this deprivation acts more quickly on rapidly growing cells and causes their death. Used in combination with other approved anticancer drugs for remission induction in acute nonlymphocytic leukemia in adults and pediatric patients. Hypersensitivity to cytarabine, pre-existing drug-induced bone marrow suppression. Use with caution in patients with preexisting drug-induced bone marrow suppression. Less serious toxicity includes nausea, vomit- n Administered by or under the direction of a physician specialist in a facility with adequate diagnostic and treatment facilities to monitor the patient and respond to any medical emergency. Must be able to monitor drug tolerance and protect and maintain a patient compromised by drug toxicity. The main toxic effect of cytarabine is bone marrow suppression with leukopenia, thrombocytopenia, and anemia. Counts may continue to fall after the drug is stopped and may reach lowest values after drug-free intervals of 12 to 14 days. Patients whose drug is withheld until "normal" peripheral blood values are attained may escape from control. Can cause fetal harm when administered to a pregnant woman, especially during the first trimester. Drug must be restarted as soon as signs of bone marrow recovery occur, or its effectiveness will be lost. Use corticosteroids for cytarabine syndrome (fever, myalgia, bone pain, occasional chest pain, maculopapular rash, conjunctivitis, malaise). There is no specific antidote; supportive therapy as indicated will help to sustain the patient in toxicity. Additional infusions of 100 mg/kg are given at 2, 4, 6, and 8 weeks posttransplant, then reduced to 50 mg/kg at 12 and 16 weeks posttransplant. May be increased to 30 mg/kg/hr in 30 minutes if no discomfort or adverse effects. May be increased in another 30 minutes to 60 mg/kg/hr if no discomfort or adverse effects. Do not exceed the 60 mg/kg/hr rate or allow the volume infused to exceed 75 mL/hr regardless of mg/kg/hr dose. Subsequent doses may be increased at 15-minute intervals using the same mg/kg/hr rates and adhering to the volume maximum of 75 mL/hr. History of a prior severe reaction associated with any human immunoglobulin preparations. Individuals with selective immunoglobulin A deficiency may develop antibodies to IgA and are at risk for anaphylaxis.

Alopecia, anaphylaxis, anorexia, facial flushing, facial paresthesias, fever, hepatotoxicity, malaise, myalgia, nausea, skin necrosis, vomiting. Bone marrow suppression may require temporary or permanent withholding of treatment. Dose will depend on tolerance of the patient, the size and location of the tumor, and the use of other forms of therapy. Calculation of the dose for obese or edematous patients should be based on body surface area. The dose intensity per 2-week cycle for adult and pediatric patients should not exceed 15 mcg/kg/day (0. May be administered in various combinations and schedules with other chemotherapeutic agents. Metastatic nonseminomatous testicular cancer: 1,000 mcg/M2 (1 mg/M2) on Day 1 as part of a combination regimen with cyclophosphamide, bleomycin, vinblastine, and cisplatin. Gestational trophoblastic neoplasia: 12 mcg/kg/day for 5 days as a single agent or 500 mcg on Days 1 and 2 as part of a combination regimen with etoposide, methotrexate, folinic acid, vincristine, cyclophosphamide, and cisplatin. Consider potential for decreased cardiac, hepatic, and renal function, and concomitant disease or drug therapy; see Elderly. Filters: Manufacturer states, "Use of some in-line cellulose ester membrane filters have resulted in loss of potency. Cellulose ester membrane filters may reduce dose by partial removal of dactinomycin. Exposure to chickenpox, herpes zoster, known sensitivity to dactinomycin, infants under 6 to 12 months of age. If skin contact occurs, remove contaminated clothing and rinse area for 15 minutes. A stinging or burning sensation indicates extravasation; Follow guidelines for handling cytotoxic agents. Inhalation of dust or vapors and contact with skin or mucous membranes, especially those of the eyes, must be avoided. May produce teratogenic effects on the fetus; use caution in men and women capable of conception. Elderly: Response similar to that in younger adults; however, recent studies suggest elderly may be at increased risk for myelosuppression; see Dose Adjustments. Toxic reactions are frequent, may be severe, and may be dose limiting; however, the severity of toxicity varies markedly and is only partly dependent on the dose administered. Abdominal pain, acne, alopecia, anaphylaxis, anorexia, bone marrow suppression. Bone marrow suppression may require withholding dactinomycin until recovery occurs. May be administered as a single dose or as a two-dose regimen with an initial dose of 1,000 mg followed 1 week later by 500 mg. To avoid foaming, alternate between gentle swirling and inversion of the vial until contents are completely dissolved. Total time from reconstitution to dilution to administration should not exceed 48 hours. Manufacturer states, "Do not co-infuse dalbavancin with other medications or electrolytes. Too-rapid infusion may cause "red-man syndrome," including back pain, flushing of the upper body, pruritus, rash, and/or urticaria. It interferes with cell wall synthesis by binding to the d-alanyl-d-alanine terminus of the stem pentapeptide in nascent cell wall peptidoglycan, thus preventing cross-linking. In vitro, dalbavancin is bactericidal against Staphylococcus aureus and Streptococcus pyogenes at concentrations similar to those sustained throughout treatment; see Indications. Mean concentrations achieved in skin blister fluid remain above 30 mg/L up to 7 days after dosing. No data available on cross-reactivity between dalbavancin and other glycopeptides, including vancomycin. Exercise caution in patients with a history of glycopeptide allergy; cross-sensitivity is possible. Consider in patients who present with diarrhea during or after treatment with dalbavancin. Maternal/Child: Use during pregnancy only if the potential benefit outweighs the possible risk to the fetus. Elderly: Consider age-related renal impairment, monitoring of renal function, and dose with caution; see Dose Adjustments. If surgery is prolonged, administer additional individualized doses during anesthesia and surgery as needed. Therapeutic or emergency dose: all Formulations: Discontinue all anesthetic agents at the first sign of a malignant hyperthermia reaction. Repeat as necessary until symptoms subside or a cumulative dose of 10 mg/kg is reached. Dose required depends on degree of susceptibility to malignant hyperthermia, length of time of exposure to triggering agent, and time lapse between onset of crisis and beginning of treatment. Post-crisis follow-up: An oral dose of 4 to 8 mg/kg/day for 1 to 3 days to prevent recurrences. Prophylactic, therapeutic, and post-crisis follow-up doses are the same as for adults; see Maternal/Child. If large volumes will be used, transfer to plastic infusion bags; do not use glass bottles; see Compatibility. Inhibits excitation-contraction coupling by interfering with the release of the calcium ion from the sarcoplasmic reticulum to reverse the physiologic cause of malignant hyperthermia and produce relaxation. The addition of dantrolene to the "triggered" malignant hyperthermic muscle cell may re-establish a normal level of ionized calcium in the myoplasm. Physiologic, metabolic, and biochemical changes associated with the malignant hyperthermia crisis may be reversed or attenuated. Treatment of malignant hyperthermia in conjunction with appropriate supportive measures. Monitor: S/S of malignant hyperthermia crises include central venous desaturation, cyanosis and mottling of the skin, hypercarbia, increased utilization of anesthesia circuit carbon dioxide absorber, metabolic acidosis, skeletal muscle rigidity, tachycardia, tachypnea and, in many cases, fever. Patient Education: May experience decreased grip strength, weakness in leg muscles, and light-headedness postoperatively. Use during pregnancy only if potential benefit justifies potential risk to the fetus. Elderly: Differences in responses between the elderly and younger patients have not been identified. Dizziness, drowsiness, loss of grip strength, and weakness in the legs are most common. Other reported side effects include erythema, hypersensitivity reactions (including anaphylaxis), injection site reactions, nausea, pulmonary edema, thrombophlebitis, tissue necrosis secondary to extravasation, urticaria. Staphylococcus aureus bloodstream infections (bacteremia), including those with right-sided endocarditis: 6 mg/kg to adult patients once every 24 hours for 2 to 6 weeks. CubiCin rF: Staphylococcus aureus bloodstream infections (bacteremia) in pediatric patients (1 to 17 years of age): Dose is based on age according to the following chart. Dosage adjustment for pediatric patients with renal impairment has not been established. If possible, administer dose following completion of hemodialysis on hemodialysis days. Use of a transfer needle that is 21 gauge or smaller in diameter or a needleless device is recommended. Allow vial to stand for 10 minutes, then gently rotate to ensure complete dilution.

Circled numbers denote the approximate percentage of substrate hydrolyzed by a particular brush border enzyme arthritis in back of knee generic diclofenac 100mg line. The same carrier actively transports glucose and galactose into the cell arthritis thumb joint pain relief generic diclofenac 100 mg online, whereas fructose is absorbed by facilitated diffusion arthritis pain patch generic diclofenac 50mg with mastercard. The carrier systems for fructose and glucose and/or galactose differ insofar as the fructose carrier cannot be energized for active transport rheumatoid arthritis triggers buy cheap diclofenac 50 mg online, whereas the glucose carrier can rheumatoid arthritis japanese diclofenac 100mg low price. Mutual inhibition of glucose or galactose transport by the presence of the other indicates that they are transported by a common carrier arthritis hip medication buy diclofenac 75 mg. The entry step is only slightly reversible because of removal of intracellular Na+ by the pump on the basolateral membrane. In the absence of oxygen, the rate of mediated uptake is proportional to concentration. When oxygen is available for cellular respiration, the uptake is greater, and the carrier system can be energized for active transport. In general the small intestine has a large disaccharidase reserve, so much that the rate-limiting step in sugar assimilation is not digestion but the absorption of free hexoses following hydrolysis. Under normal circumstances the major portion of sugar assimilation is complete in the proximal jejunum. Regulation of Absorption the capacity of the human small intestine to absorb free sugars is enormous. It has been estimated that hexoses equivalent to 22 pounds of sucrose can be absorbed daily. However, chemoreceptors and osmoreceptors in the proximal small intestine control the motility and emptying of the stomach through a negative feedback process mediated by hormones and neural reflexes. As an example, a volume of isotonic citrate solution of 750 mL that is placed in the human stomach passes into the small bowel in 20 minutes. The volume delivered in the same time is reduced if sucrose or glucose is added to the citrate solution. Absorption of Digestion Products For the body to use food-derived monosaccharides, they must be absorbed. Although aqueous channels are present between enterocytes and pores in brush border membranes, dietary hexoses are too large to penetrate the membranes in any significant degree by passive diffusion. Fructose exits the basolateral membrane by another facilitated diffusion Abnormalities in Carbohydrate Assimilation It is obvious from the foregoing considerations that polysaccharides and oligosaccharides are absorbed as monosaccharides. Carbohydrates remaining in the intestinal lumen increase the osmotic pressure of the luminal contents because of defects in digestion and absorption. Bacterial fermentation of these carbohydrates in the lower small intestine and colon adds to this osmotic effect. Absorption involves the rapid movement from lumen to blood by an entry step and exit step mediated by two separate carrier molecules with specificity for hexose. When Na+ is pumped from the cell, more Na+ and glucose are transported into the cell from the lumen. Diarrhea caused by the poor assimilation of dietary carbohydrates is most commonly caused by deficiencies in carbohydrate-splitting enzymes in the intestinal brush border. Lactase deficiency, the most frequently observed congenital disaccharidase deficiency, can exist in the absence of any other intestinal malfunction. In fact, a large percentage of the individuals of most races, other than those originating in Northern Europe, will lose lactase activity later in life. Intolerance of sucrose and isomaltose is a rare disease found primarily in children. Thus maltose intolerance would require the simultaneous absence of all enzymes possessing maltase activity. Maldigestion of starch in humans is nonexistent because pancreatic amylase is secreted in tremendous excess. In these cases the patients thrive and show no symptoms when they are fed fructose. Glucose and chemically related sugars are absorbed by an Na+-dependent secondary active transport process, whereas fructose is absorbed by Na+-independent facilitated diffusion. Celiac disease, certain bacterial infections, and some protozoan and helminth infections are associated with inflammation and structural derangements in the small bowel mucosa. It is not uncommon to find lactase deficiency as a long-term consequence of intestinal disease, because this enzyme is present in the intestine at low levels compared with maltase and sucrase. Glucose or galactose tolerance tests should be performed to exclude monosaccharide malabsorption as the cause of a flat lactose tolerance curve. After an overnight fast, adult patients are fed 50 g of lactose in a 10% aqueous solution (children are usually fed 2 g/kg of body weight). Blood samples are taken for glucose analysis before and at 5, 10, 15, 30, 45, and 60 minutes after lactose administration. An increase in blood glucose of at least 25 mg/dL over fasted levels indicates normal hydrolysis of lactose and normal absorption of the glucose product. A flat lactose tolerance curve or failure to observe a rise in blood glucose to more than 25 mg/dL after lactose ingestion indicates low lactase activity. In this case the test may be repeated or, if laboratory facilities permit, intestinal biopsy specimens can be collected and examined for enzyme activity. In dealing with biopsy specimens, enzyme activity usually is expressed as units per gram of tissue protein. People from Eastern countries, who eat a high-carbohydrate diet in the form of rice, consume less protein than those from meat-eating Western societies, where a typical diet contains more than 100 g per day. Secretions from the salivary glands, stomach, pancreas, and intestines along with sloughed cells add another 40 g protein per day, which is digested and absorbed in the same manner as dietary protein. The enzyme precursor pepsinogen is secreted by chief cells in response to a meal and low gastric pH. Pepsin is an endopeptidase with specificity for peptide bonds involving aromatic l-amino acids. Pepsin activity terminates when the gastric contents mix with alkaline pancreatic juice in the small bowel. The two general classes of pancreatic proteases are endopeptidases and exopeptidases. The basis of classification and the particular characteristics of specific enzymes belonging to each class are given in Table 11. Trypsinogen, which lacks proteolytic activity, is activated by enterokinase, an enzyme located on the brush border of duodenal enterocytes. The exact chemical composition of enterokinase is not known; however, the fact that the molecule is 41% carbohydrate probably prevents its rapid digestion by proteolytic enzymes. The activity of enterokinase is stimulated by trypsinogen, and it is released from the brush border membrane by bile salts. Active trypsin, once formed, acts autocatalytically in the manner of enterokinase to activate the bulk of trypsinogen. Chymotrypsinogen is activated by cleavage of the peptide bond between arginine and isoleucine, which are, respectively, the fifteenth and sixteenth amino acid residues at the N-terminus. Although structural rearrangement occurs, no peptide fragment is released because of a disulfide bond between the cysteine residues at positions 1 and 122 in the protein chain. Cleavage at other points in the chymotrypsinogen molecule produces other molecular species of chymotrypsin having relatively little physiologic importance. Once in the small intestine, pancreatic enzymes undergo rapid inactivation because of autodigestion. Development of Pancreatitis In developed countries, 80% of the cases of acute pancreatitis are the result of either biliary stone disease or ethanol abuse. As pointed out previously, trypsin plays a central role in the activation of other pancreatic zymogens. Normally trypsin remains as inactive trypsinogen until it is secreted into the duodenal lumen. The mechanisms responsible for the intracellular activation of trypsin are not totally clear. One hypothesis states that it is catalyzed by lysosomal hydrolases after the colocalization of these hydrolases with digestive zymogens within membrane-bound organelles during the early stages of pancreatitis. Premature activation of trypsinogen within the pancreas initiates the entire activation cascade of other proteases, results in autodigestion of pancreatic cells, and causes acute pancreatitis. These include synthesis of pancreatic trypsin inhibitors, isolation of zymogens from lysosomes, and a site on trypsin that is susceptible to digestion by trypsin itself. Thus when trypsin comes into contact with other trypsin molecules, it is able to cleave them and irreversibly inactivate the enzyme. Research has located a single guanine-to-adenine gene mutation that results in the substitution of histidine for arginine (R117H). This substitution prevents trypsin from being inactivated and was discovered in several families of patients with hereditary pancreatitis. Thus this mutation eliminates one of the failsafe mechanisms preventing the premature activation of trypsinogen and is the basis for at least one form of hereditary pancreatitis. The process begins in the lumen when enterokinase cleaves a hexapeptide from trypsinogen and converts it to the active enzyme trypsin. Membrane digestion and absorption are closely related phenomena in protein assimilation, and physiologists have been occupied by two fundamental questions concerning them: (1) In what form do products of proteolysis cross the brush border membrane of the epithelial cell Other amino acids and some of those absorbed by active transport can also be absorbed by facilitated diffusion processes that do not require Na+ (Table 11. Thus the entry of the amino acid is coupled with the movement of a proton down its electrochemical gradient. Studies of competition have led to the recognition of several different carrier systems for amino acid absorption (see Table 11. There is little doubt that the absorption of free amino acids by gut mucosa is physiologically important. Moreover, greater amounts of total nitrogen are absorbed from a solution of trypsin hydrolysate of proteins than from an equivalent solution of amino acids in free form. Competition for transport between two chemically related amino acids is not observed when the same two acids are absorbed after ingestion of their dipeptides and tripeptides. Luminal digestion yields 20% free amino acids and 80% peptides consisting primarily of two to six amino acid residues. The absorptive capacity for dipeptides and tripeptides is greater in the proximal intestine, whereas the capacity for absorbing single amino acids is greater in the distal intestine. The current explanation of these findings is that a separate carrier system for small peptides is involved in absorption. If saturation of the system occurs under physiologic conditions, the maximum rate of uptake becomes limiting. If, however, a second carrier for dipeptides or tripeptides of glycine is present, the amino acids can enter the cell in small peptide form. Luminal digestion of a protein meal produces approximately 20% free amino acids and 80% small peptides. As with the free acids, dipeptides and tripeptides resulting from digestion can be absorbed intact by a carrier-mediated process. However, tetrapeptides, pentapeptides, and hexapeptides are poorly absorbed; instead they are hydrolyzed by brush border peptidases to free amino acids or smaller absorbable peptides. This transport process is independent of the Na+ gradient and is stimulated by an inwardly directed H+ gradient. The acidic microclimate pH that normally exists on the luminal surface of the brush border membrane provides the driving force for the peptide transport system. Peptides that enter enterocytes are hydrolyzed by cytoplasmic peptidases to amino acids. These, in turn, diffuse or are moved by carrier-mediated processes from the intracellular compartment, across the basolateral membrane, into the blood. As is the case with the apical membrane, several different carriers exist in the basolateral membrane (see Table 11. A few peptides enter the blood intact, and this may explain why certain biologically active peptides exert their effects when they are given orally. Abnormalities in Protein Assimilation Pancreatic insufficiency caused by various diseases, including cystic fibrosis and hereditary pancreatitis, may be associated with a decrease or absence of trypsin and may lead to poor digestion of protein. Cases of primary proteinase deficiency caused by congenital trypsinogen deficiency have been reported. In those patients, chymotrypsin and carboxypeptidase activities are lacking also, because trypsin cannot be formed to activate the precursors of these pancreatic proteases. Tryptophan is also the precursor for the neurotransmitter serotonin, and its decreased synthesis may contribute to the neurologic symptoms associated with this disease. Dietary lipids include such substances as triacylglycerides, fat-soluble vitamins (A, D, E, and K), phospholipids, sterols, hydrocarbons, and waxes that compose cell walls or membranes of plants and/or animals. The principles of lipid assimilation are dealt with through a consideration of triglycerides, phospholipids, and sterols. The propensity of lipids to form ester linkages and the insolubility of lipids in water make their digestion and absorption a complex process. Unlike carbohydrates and proteins, lipids enter epithelial cells by a sequence of chemical and physical steps that render water-insoluble molecules capable of being absorbed by passive diffusion. The process depends on four major events: (1) secretion of bile and various lipases, (2) emulsification, (3) enzymatic hydrolysis of ester linkages, and (4) the solubilization of lipolytic products within bile salt micelles. Results are from studies carried out in six normal subjects and six cystinuric patients. The intestinal malabsorptive condition is of little or no consequence in the disability produced by cystinuria, given that the affected amino acids are absorbed as small peptides. However, the disease is severe because cystine has low solubility in water, and as the urine is concentrated in the distal nephron, cystine precipitates and forms stones. An interesting finding is that, although neutral amino acids are not absorbed, they readily appear in the blood after ingestion of their dipeptides. This is compelling evidence that absorption of the dipeptides of certain amino acids is the result of a completely separate process from the one involved in the transport of free amino acids. These patients lose significant amounts of amino acids in their urine, and the condition may become significant in those whose dietary protein intake is low. One function of bile salts released into the duodenum is to perpetuate the emulsification of fat droplets by decreasing the surface tension at the oil-water interface.

The maximum dose is 6 Gm/kg/24 hr or 250 Gm in 48 hours (250 Gm is equal to 5 liters of 5% or 1 liter of 25%) arthritis pain in wrist diclofenac 75mg overnight delivery. In the absence of active hemorrhage arthritis fingers popping cheap diclofenac amex, the total dose usually does not exceed the normal circulating mass of albumin arthritis pain relief apr cheap diclofenac 50 mg visa. Then begin with 25 Gm and adjust as necessary to maintain albumin level from 2 to 3 Gm/dL arthritis mayo clinic purchase on line diclofenac. Acute nephrosis or acute nephrotic syndrome: 20 to 25 Gm of a 25% solution with a loop diuretic zoloft arthritis pain buy diclofenac 50 mg amex. Another recommends 1 to 2 hours before blood transfusion or with transfusion (exchange 50 mL of albumin 25% for 50 mL plasma) arthritis shots discount diclofenac 100 mg mastercard. Manufacturers state, "Do not mix with protein hydrolysates, amino acid mixtures, or solutions containing alcohol. A too-rapid rate, especially in the presence of normal blood volume, may cause circulatory overload and pulmonary edema. As volume approaches normal, slow 5% to 1 to 2 mL/min and 25% to 1 mL/min to prevent circulatory overload and pulmonary edema. Hypoproteinemia: 2 to 3 mL/min in adults; a single dose over 30 to 120 minutes in pediatric patients. Infants and other pediatric patients: For uses other than hypovolemia and hypoproteinemia, the rate of administration should be about one-fourth to one-half the adult rate. A sterile natural plasma protein substance prepared by a specific process, which makes it free from the danger of serum hepatitis. A blood volume expander that accounts for 70% to 80% of the colloid oncotic pressure of plasma. Expands blood volume proportionately to amount of circulating blood, improves cardiac output, prevents marked hemoconcentration, aids in reduction of edema, and raises serum protein levels. Low sodium content helps to maintain electrolyte balance and should promote diuresis in presence of edema (contains 130 to 160 mEq sodium/L). Also acts as a transport protein that binds both endogenous and exogenous substances, including bilirubin and certain drugs. Unlabeled uses: Large-volume paracentesis, spontaneous bacterial peritonitis in patients with cirrhosis. Anemia (severe) or cardiac failure in the presence of normal or increased intravascular volume, hypersensitivity to albumin, pulmonary edema. Is not a substitute for whole blood in situations in which both the oxygen-carrying capacity and plasma volume expansion provided by whole blood are required. Trauma patients with concomitant traumatic brain injuries may also be at risk for increased mortality. Elderly: Monitor fluid intake carefully; more susceptible to circulatory overload and pulmonary edema. Chills, fever, headache, hypotension, nausea, salivation, skin rash or hives, tachycardia, vomiting. Major: Congestive heart failure, decreased myocardial contractility, hypersensitivity reactions including anaphylaxis (rare), precipitous hypotension, pulmonary edema, salt and water retention. After 9 days of rest, repeat for up to 14 more doses; this constitutes one course (two 5-day [14 or fewer doses] treatment cycles separated by a rest period of 9 days). Retreatment: Evaluate for response 4 weeks after course completion and again before scheduling start of the next course. Additional courses are considered if there is some tumor shrinkage following the previous course and retreatment is not contraindicated. At least 7 weeks from hospital discharge should elapse before a subsequent course is administered. Median number of doses actually administered in a first course is 20 for metastatic renal cell carcinoma patients and 18 for metastatic melanoma patients. May Give Next Dose if 35 Sepsis syndrome has resolved; patient is clinically stable; infection is under treatment. May consider a new course of treatment in 7 weeks if all signs of hepatic failure have resolved. Do not use any other diluent or infusion solution; may cause increased aggregation. A genetically engineered recombinant protein that possesses the biologic activity of naturally occurring interleukin-2. Following a short infusion, aldesleukin distributes rapidly into the kidneys, liver, lungs, and spleen. Eliminated by metabolism in the kidney with little or no bioactive protein excreted in urine. Eligibility requirements for treatment are specific; see Precautions and Contraindications. Retreatment is permanently contraindicated in patients who experienced specific toxicities in a previous course of therapy (see the following chart). Contraindications for Retreatment With Aldesleukin Organ System Symptom Sustained ventricular tachycardia $5 beats. Intensive care facilities and specialists in cardiopulmonary and/or intensive care medicine must be available. Extravasation of protein and fluid into the extravascular space will lead to edema and the creation of new effusions. Mental status changes due solely to aldesleukin may progress for several days before recovery begins. Clinical manifestations include agitation, ataxia, change in mental status, hallucinations, obtundation, speech difficulties, and coma. Neurologic S/S usually resolve following discontinuation of therapy; however, there have been reports of permanent damage. Monitor: A central venous catheter (double or triple lumen) is frequently ordered on admission (required for continuous infusion). One line could suffice if absolutely necessary since aldesleukin would be discontinued when colloids are administered. Pre-existing bacterial infections should be adequately treated before beginning therapy. Patients with indwelling central lines are at increased risk for infection with gram-positive organisms. Antibiotic prophylaxis with ciprofloxacin, nafcillin, oxacillin, or vancomycin has been associated with a reduced incidence of staphylococcal infections. Adequate pulmonary function, normal arterial blood gases, and normal ejection fraction and unimpaired wall motion (confirmed by thallium stress test and/or a stress echocardiogram) should be documented. Requires constant management and balancing of effects of fluid shifts to prevent the consequences of hypovolemia. Continue administration of these drugs until 12 hours after last dose of aldesleukin. Antiemetics, antidiarrheals, antichill/rigors (meperidine), antihistamines, and moisturizing skin lotions will also be used throughout treatment; see Antidote for specifics. Evaluate fluid, electrolyte, and acid-base status promptly if any of the above occur. Contraceptive measures required before initial administration and throughout treatment. Elderly: Response rates and toxicity similar to that seen in younger adults; however, some increased incidence of severe urogenital toxicities and dyspnea was noted in the elderly. Reactions have included chills, diarrhea, edema, fever, hypotension, nausea, oliguria, pruritus, rash, and vomiting. Most reactions were reported when contrast media were given within 4 weeks after the last dose of aldesleukin. Frequent, predictable, often severe; are usually clinically manageable and frequently require intensive care management. Begin to occur shortly after therapy begins (chills, fatigue, fever, hypotension, nausea, vomiting). Initially anorexia, arthralgia, chills, fatigue, fever, nausea, and vomiting occur. Initial symptoms of capillary leak syndrome are edema, electrolyte abnormalities, hypotension, oliguria, respiratory distress, significant weight gain, tachycardia. Hemodynamic effects similar to septic shock may be caused by tumor necrosis factor. Erythematous rash and pruritus (can progress to dry desquamation) can occur in almost all patients and are extremely uncomfortable.

Hold any subsequent dose for failure to maintain organ perfusion; see Dose Adjustments. Fever is routinely treated with acetaminophen and indomethacin or naprosyn; increased doses may be needed. Treat arrhythmias as indicated (usually sinus or supraventricular tachycardia [adenosine, verapamil]). All treatment is supportive; recovery should begin within a few hours of cessation of aldesleukin. Premedication, dose escalation to the recommended maintenance dose, and antiinfective prophylaxis are required. Premedication: Diphenhydramine (Benadryl) 50 mg and acetaminophen (Tylenol) 500 to 1,000 mg should be administered 30 minutes before the first dose, at dose escalations, and as clinically indicated. For cases in which severe infusion-related reactions have occurred, corticosteroids may be administered to help prevent or minimize subsequent reactions. In most cases, dose escalation to the maintenance dose of 30 mg can be achieved in 3 to 7 days. Single doses greater than 30 mg or cumulative weekly doses greater than 90 mg have been associated with an increased incidence of pancytopenia and should not be administered. Premedication: Corticosteroids: Administer high-dose corticosteroids (1,000 mg methylprednisolone [Solu-Medrol] or equivalent) immediately before Lemtrada infusion for the first 3 days of each treatment course. Second treatment course: 12 mg/day as an infusion on 3 consecutive days (36 mg total courses of 12 mg/day on 3 consecutive days (36 mg total dose) may be administered as needed at least 12 months after the last dose of any prior treatment courses. Campath and Lemtrada Withhold alemtuzumab during serious infections or other serious adverse reactions until resolution. Alemtuzumab Dose Modification for Neutropenia or Thrombocytopenia Hematologic Values 3 Dose Modificationa Withhold alemtuzumab therapy. If the delay between dosing is equal to or more than 7 days, resume alemtuzumab therapy at 3 mg and escalate to 10 mg and then to 30 mg as tolerated; see Usual Dose and Rate of Administration. Lemtrada: A single dose as an infusion over 4 hours starting within 8 hours of dilution. The proposed mechanism of action for Campath is antibody-dependent cellular-mediated lysis following cell surface binding of Campath to the leukemic cells. Following cell surface binding to T- and B-lymphocytes, Lemtrada results in antibody-dependent cellular cytolysis and complement-mediated lysis. Lymphocyte counts then increase slowly over time, with B-cell counts recovering within 6 months and T-cell counts recovering after 12 months. Mean half-life was 11 hours (range 2 to 32 hours) after the first 30-mg dose and was 6 days (range 1 to 14 days) after the last 30-mg dose. The half-life of Lemtrada was approximately 2 weeks and was comparable between courses. Campath Administered by or under the direction of a physician specialist in a facility with adequate diagnostic and treatment facilities to monitor patient and respond to any medical emergency. Serious and sometimes fatal bacterial, viral, fungal, and protozoan infections have been reported. Prophylaxis directed against Pneumocystis jiroveci pneumonia and herpes virus infections is recommended. Prophylaxis has been shown to decrease but not eliminate Lemtrada the occurrence of these infections. May cause serious, sometimes fatal, autoimmune conditions such as immune thrombocytopenia and antiglomerular basement membrane disease. Several other autoimmune disorders have also been reported in a small number of patients. In patients with ongoing thyroid disorder, consider benefit versus risk of Lemtrada administration. Monitor weekly or more frequently if worsening anemia, neutropenia, or thrombocytopenia develops. Acute infusionrelated reactions were most common during the first week of therapy in clinical studies. Gradual escalation to the recommended maintenance dose is required at the initiation of therapy and after interruption of therapy for 7 or more days. Treat confirmed infection or viremia as indicated with ganciclovir (Cytovene) or equivalent. After 48 months, perform testing based on clinical findings that suggest autoimmunity. Symptoms of autoimmune hemolytic anemia may include chest pain, dark urine, jaundice, tachycardia, and weakness. Serious infusion reactions have been reported more than 24 hours after an infusion.

Do not administer solutions containing dextrose through the same administration set as blood; may result in pseudoagglutination or hemolysis is arthritis in your back a disability cheap diclofenac 50mg otc. If hypotension occurs at lower infusion rate arthritis diet psoriatic discount 75mg diclofenac with visa, the infusion rate should be rapidly increased until adequate blood pressure is obtained arthritis diet tomatoes cheap diclofenac 100mg line. If hypotension continues psoriatic arthritis diet gluten generic diclofenac 100 mg with visa, dopamine should be discontinued and a more potent vasoconstrictor agent arthritis in the knee and yoga discount diclofenac 75mg with mastercard. If a disproportionate rise in diastolic pressure is observed arthritis virus buy 100mg diclofenac mastercard, the infusion rate should be decreased and the patient observed for further evidence of predominant vasoconstrictor activity unless such an effect is desired. Dopamine Infusion Rate (mL/hr): 400 mcg/mL Concentration Desired Dose 50 kg (mL/hr) 5 mcg/kg/min 37. At medium doses (2 to 10 mcg/kg/min), beta-adrenoceptors are stimulated, resulting in improved myocardial contractility, increased sinoatrial rate, and enhanced impulse conduction in the heart. Systolic and pulse pressure may increase, but there is little, if any, effect on diastolic pressure at these doses. At higher doses (10 to 20 mcg/kg/min), alpha-adrenoceptors are stimulated, resulting in vasoconstriction and an increase in blood pressure. At doses above 20 mcg/kg/min, alpha effects predominate and vasoconstriction may compromise circulation in the limbs and override the dopaminergic effects of dopamine, reversing renal dilation and natriuresis. It has an onset of action of 5 minutes, a duration of action of 10 minutes, and a plasma half-life of 2 minutes. Unlabeled uses: Chronic obstructive pulmonary disease, congestive heart failure, infant respiratory distress syndrome, symptomatic bradycardia, calcium channel blocker overdose, beta-blocker overdose, and drug-induced hypovolemic shock; consult literature. Hypersensitivity to any components (contains sulfites), pheochromocytoma, uncorrected tachyarrhythmias, ventricular fibrillation. Premixed solutions containing dextrose may be contraindicated in patients with known allergies to corn or corn products. Monitor: Recognition of signs and symptoms of hemodynamic imbalance and prompt treatment with dopamine will improve prognosis. If possible, check central venous pressure or pulmonary wedge pressure before administration and as ordered thereafter. Vasospastic events have been reported when dopamine is infused through the umbilical artery. Gangrene of the extremities has occurred with high doses administered for prolonged periods and in patients with occlusive vascular disease receiving a low dose of dopamine. For accidental overdosage with hypertension, reduce rate or temporarily discontinue until condition stabilizes. Phentolamine, an alpha-adrenergic blocker, may be useful in an overdose situation that does not respond to discontinuation of dopamine. To prevent sloughing and necrosis in areas where extravasation has occurred, use a fine hypodermic needle to inject 5 to 10 mg of phentolamine (Regitine) diluted in 10 to 15 mL normal saline liberally throughout the tissue in the extravasated area. To prepare a 250-mg dose from a 500-mg vial, follow the directions above for the 500-mg vial dilution. Bactericidal to selected aerobic and anaerobic gram-positive and gram-negative bacteria. Bactericidal activity results from the inhibition of bacterial cell wall synthesis. Stable to hydrolysis by most betalactamases, including penicillinases and cephalosporinases produced by gram-positive and gram-negative bacteria, with the exception of carbapenem-hydrolyzing betalactamases. Penetrates into several body fluids and tissues, including those at the site of infection for the approved indications. Limitation of use: Doripenem is not approved for the treatment of ventilator-associated bacterial pneumonia. Consider in patients who present with diarrhea during or after treatment with doripenem. Patient Education: Promptly report S/S of hypersensitivity reaction or pain at injection site. Maternal/Child: Category B: should be used during pregnancy and breast-feeding only if clearly needed. Elderly: Response similar to that seen in younger patients, but greater sensitivity of some older individuals cannot be ruled out. If administration of doripenem is necessary, supplemental anticonvulsant therapy should be considered. The most common adverse reactions are diarrhea, headache, nausea, phlebitis, and rash (allergic rash, bullous dermatitis, erythema, erythema multiforme, macular/papular eruptions, urticaria). Post-Marketing: Anaphylaxis, interstitial pneumonia, leukopenia, neutropenia, renal impairment/failure, seizures, Stevens-Johnson syndrome, thrombocytopenia, and toxic epidermal necrolysis. Repetitive doses are to be used only if the initial dose elicits a positive response. Alternately, an initial dose of 1 mg/kg may be followed by a continuous infusion of 1 to 2 mg/kg/hr. If a relapse occurs, resume injections every 1 to 2 hours until arousal is sustained or a total maximum daily dose (3 Gm) is given. Allow patient to sleep until 24 hours after the first injection; use assisted or automatic respiration if necessary. After this 24-hour lapse, repeat procedure until patient breathes spontaneously and sustains the desired level of consciousness or until the maximum dose (3 Gm) has been given. Alternately, an initial dose of 2 mg/kg may be followed by a continuous infusion of 2 to 3 mg/kg/hr. Safety and effectiveness in pediatric patients under 12 years of age not established; see Maternal/Child. Follow with a continuous infusion of 1 mg/kg/hr titrated to the lowest effective dose. Chronic obstructive pulmonary disease: Dilute 400 mg in 180 mL infusion fluid (2 mg/mL). Manufacturer states, "Admixture with alkaline solutions such as aminophylline, furosemide (Lasix), sodium bicarbonate, or thiopental (Pentothal) will result in precipitation or gas formation. Post-anesthesia respiratory depression: Total desired dose of undiluted medication over 5 minutes. Infusion rate may start at 5 mg/min; decrease to 1 to 3 mg/min with observance of respiratory response. If an infusion is used after the initial priming dose, rate may start at 1 to 3 mg/min depending on patient response. Affects medullary respiratory center to increase the depth of respiration and to slightly increase the rate. Achieves maximum effect in 2 minutes and lasts about 5 to 12 minutes with a single dose. Unlabeled uses: Has been used for the treatment of neonatal apnea when methylxanthines. Cardiovascular impairment (significant), cerebral edema, cerebrovascular accidents, convulsive states of any etiology, coronary artery disease, head injury, heart failure (uncompensated), hypertension (severe), inadequate ventilation capacity, known hypersensitivity to doxapram or any of its components, neonates, proven or suspected pulmonary embolism. Moderate depression is classified as Class 2 (comatose, will not withdraw from painful stimuli, reflexes intact) or Class 3 (comatose, reflexes absent, no depression of circulation or respiration). Adjust rate of infusion and oxygen delivery as indicated by arterial blood gases and patient response. Maternal/Child: Category B: safety for use in pregnancy, breast-feeding, and pediatric patients under 12 years of age not established. Depending on severity, physician may elect to continue the drug at a reduced rate of administration or discontinue it. Available as a single-use injection containing either 4 mcg/2 mL or 2 mcg/mL and as a multidose injection containing 4 mcg/2 mL. Metabolizes to a naturally occurring, biologically active form of vitamin D2 that regulates blood calcium at levels required for essential body functions. In uremic patients, deficient production of biologically active vitamin D metabolites leads to secondary hyperparathyroidism, which contributes to the development of metabolic bone disease. Evidence of vitamin D toxicity, hypercalcemia, hyperphosphatemia, or known hypersensitivity to any ingredient in this product; see Precautions. Progressive hypercalcemia due to overdose of vitamin D and its metabolites may require emergency attention. Acute hypercalcemia may exacerbate tendencies for cardiac arrhythmias and seizures and may potentiate the action of digoxin drugs. Chronic hypercalcemia can lead to elevated Ca 3 P product, and generalized vascular and other soft-tissue calcification. Radiographic evaluation of suspect anatomical regions may be useful in the early detection of generalized vascular or other soft-tissue calcification. After initiating doxercalciferol therapy, the dose of calcium-containing phosphate binders should be decreased to correct persistent mild hypercalcemia (10. Strict adherence to dietary supplementation of calcium and restriction of phosphorus is required to ensure optimal effectiveness of therapy. Maternal/Child: Category B: safety for use in pregnancy not established; use only if clearly needed. Use caution when doxercalciferol is prescribed concomitantly with digoxin compounds. Signs and symptoms of vitamin D intoxication associated with hypercalcemia include: Early: anorexia, bone pain, constipation, dry mouth, headache, metallic taste, muscle pain, nausea, somnolence, vomiting, and weakness. High intake of calcium and phosphate concomitant with doxercalciferol may lead to similar abnormalities. Treatment of patients with clinically significant hypercalcemia (more than 1 mg/dL above the upper limit of normal range) consists of immediate dose reduction or interruption of the therapy and includes a low-calcium diet, withdrawal of calcium supplements, patient mobilization, attention to fluid and electrolyte imbalances, assessment of electrocardiographic abnormalities (critical in patients receiving digoxin), forced diuresis, and hemodialysis or peritoneal dialysis against a calcium-free dialysate, as warranted. Monitor serum calcium levels frequently until calcium levels return to within normal limits. When serum calcium levels return to within normal limits (usually 2 to 7 days), therapy may be restarted at a dose that is at least 1 mcg lower than prior therapy. Should a hypersensitivity reaction occur, discontinue doxercalciferol and initiate appropriate treatment and monitoring as indicated. When used in combination with other agents, the most common dose of doxorubicin is 40 to 75 mg/M2 every 21 to 28 days. Adjuvant treatment of operable node-positive breast cancer: Treatment protocol includes doxorubicin, cyclophosphamide, and docetaxel. Doxil (liposomal DoxorubiCin) Do not substitute Doxil for conventional doxorubicin. Continue regimen for 8 cycles or until disease progression or the occurrence of unacceptable toxicity. Breast cancer with lymph node involvement after resection: Reduce dose to 75% of the starting dose for neutropenic fever/infection. Adjust or delay a dose as described in the product literature at the first sign of a Grade 1 or higher adverse event. Modification Dose adjustments for Doxil in combination therapy with bortezomib for treatment of multiple myeloma are listed in the following chart. Filters: Conventional doxorubicin: Data not available from manufacturer; however, one source indicates no evidence of drug loss when administered through a 0. Primarily occurs during the first infusion; may resolve with a reduced rate or may take up to a day after infusion completed to resolve. Begin with an initial rate of 1 mg/min to minimize the risk of infusion reactions. If no adverse infusion-related effects, the rate may be increased from the initial rate of 1 mg/min to evenly distribute and complete infusion over 1 hour. The small size of these liposomes and their persistence in the circulation enable them to evade immune system detection and penetrate the often altered and/or compromised vasculature of tumors. Once distributed to tumor tissue, the doxorubicin is released by an unknown mechanism. It differs from conventional doxorubicin because it mostly confines itself to vascular fluid volume. Conventional DoxorubiCin: Adjuvant therapy in women with evidence of axillary lymph node involvement following resection of primary breast cancer. Differences in liposomal products as well as conventional products can substantially affect the functional properties of these agents; do not substitute one agent for another. Life-threatening or fatal left ventricular failure may occur during therapy or months after therapy is completed. Cardiotoxicity occurs with increasing frequency as cumulative doses increase above 300 mg/M2. Prior use of other anthracyclines or anthracenediones should be included in calculations of total cumulative dose. Patients with active or dormant cardiovascular disease or patients who have received radiotherapy to the mediastinal area or concomitant therapy with other anthracyclines. Consider the use of dexrazoxane to reduce the incidence and severity of cardiomyopathy due to doxorubicin in patients who have received a cumulative dose of 300 mg/M2 and who will continue to receive doxorubicin. Doxil: Benefits must outweigh risks if Doxil is used in patients with a history of cardiovascular disease. Malignancies have been diagnosed both during treatment and up to 6 years after completion of therapy. Testing for renal and hepatic function may also be indicated; see Dose Adjustments. Endomyocardial biopsy or gated radionuclide scans have been used to monitor potential cardiac toxicity. Sepsis in a neutropenic patient has resulted in discontinuation of treatment and, in rare cases, death.
