Interacting drugs- summary
+ Amphotericin B
concurrent administration enhance the potential for renal toxicity, bronchospasm anfd hypertension
concurrent administration potentiate hypokalemia and predispose the patient to cardiac dysfunction. Do not give unless necessary to control adverse reactions
concurrent administratin increases neurotoxicity and nephrotoxicity. If used concomittantly, closely monitor renal and hematologic function
Amphotericin B +
incr nephrotoxic effects of cyclosporine increased. Take extra care when administering amphotericin B with other nephrotoxic agents
concurent administration induce hypokalemia and potentiate digitalis toxicity
flucytosine toxicity increased by increasing its cellular uptake or impair or impair renal excretion
ampotericin B-induced hypokalemia may enhance the curariform affect agents (NNBs) of skeletal muscle relaxants
Prevention of adverse reactions
Most patients will exhibit some intolerance, often at less than full therapeutic dosage.
Severe reactions may be lessened by giving aspirin, antipyretics(eg acetaminiophen) antihistamines and antiemetics before the infusion and by maintaining sodium balance.
Administration on alternate days may decrease anorexia and phlebits.
Small doses of IV adrenal corticosteroids given prior to or during infusion may decrease febrile conditions.
Keep the dosage and duration of such corticosteroid therapy to a minimum.
Most frequent -
General toxic reactions- fever ( sometimes with shaking chills), headache, anorexia, malaise, generalised pain, including muscle and joint pains
Respiratory- respiratory failure, respiratorty disorder, pneumonia Metabolic/ Nutrional- bilirubinemia, increased serum creatinine, acidosis
Renal- hyperkalemia, azotemia, kidney failure, renal tubular acidosis.
GI- nausea, vomiting, dyspepsia, diarrhea, cramping, epigastric pain, abdominal pain. Hematologic- normochromic, normocytic anemia.
Local- venous pain at the injection site with phlebitis, an thrombophlebitis Miscellaneous- weight loss, multiple organ failure, sepsis, infection, rash
Hypersensitivity- broncospasm, wheezing, asthma
Cardiovascular- arrhythmias, ventricular fibrillation,cardiac arrest, hypertension, hypotension, cardiac faliure, pulmonary edema, shock, myocardial infarction, tachypnea, pulmonary embolus, cardiomyopathy
Hemotologic- caogulation defects, thrmbocytopenia, leukopenia, agranulcytosis, eosionophillia, leukocytosis
CNS- peripheral neuropathy, convulsions, encephalopathy, extrapyrimidal symptoms, other neurological symptoms.
Special senses- hearing loss, tinnitus, transcient vertigo, blurred vision, diplopia
GI- hemorrhagic gastroenteritis, acute liver failure, hepatitis, jaundice, anorexia,
Renal- acute renal failure, decreased renal function, anuria, oliguria, permanent damage is often related to large total dose (>5g)
Dermatologic- maculopapular rash, pruritus,(without rash), exfoliative dermatitis, erythema multiforme.
Miscellaneous- anaphylactoid reactions, flushing, dyspnea, impotence, myasthenia
Benefits of use must be weighed against drugs untoward and dangerous side effects.Hypersens.
Perform BUN and serum creatinine or endogenous creatinine clearance tests at least weekly during therapy.
Discontinue therapy if liver function test results are abnormal (elevated alkaline phosphatase and bilirubin)
Monitor renal function frequently during amphotericin B therapy.
It is also advisable to monitor liver function, serum electrlytes (particularly magnesium and potassium), blood counts and hemoglobin concentrations on a regular basis.
Prolonged therapy- is usually necessary. Use only in hospitalized patients or in those under close medical observation.
Therapy interruption- whenever medication is interrupted for > 7 days, resume therapy with the lowest dosage level. Increase gradually.
Pulmonary reactions- characterized by acute dyspnea, hypoxemia, and interstitial infiltrates have been observed in neutropenic patients receiving amphotericin B and leucocyte transfusions.
Administer amphotericin B cautiously in patients receiving leucocyte transfusions and separate the infusion as far as possible from the time of leuckocyte transfusion
Laboratory tests- Serum electrolyte abnormalities- hypomagnesemia, hypocalcemia.
Renal function abnormalities- increased BUN
Other test abnormalities- acidosis, hypermylasemia, hypoglycemia, hyperglycemia.
Nephrotoxicity- renal damage the most important toxic effect is a limiting factor for the use of amphotericin B. Renal dysfunction usually improves upon interrruption of therapy, dose reduction or increased dosing interval, however some permanent impairment often occurs.
Acute reactions - including fever, shaking chills, hypotension, anorexia, vomiting, nausea, headache and tachypnea are common 1 to 3 hours after starting an IV infusion. These reactions are usually severe with first few doses of amphotericin B and usually diminish with susequent doses.
Rapid infusion- has been associated with hypotension, hypokalemia, and arrhythmias and shock and should be avoided. Diabetic control must be instituted before successful treatment with amphotericin B can be accomplished.
Hypersensitivity- If severe respiratory distress occurs, discontinue the infusion immediately. Do not give further infusions.
Renal function impairment- use with care in patients with reduced renal function, frequent monitoring is recommended.
Pregnancy- Use during pregnancy only if clearly needed.
Lactation- it is not known whether amphotericin B is excreted in breast milk. However, consider discontinuing nursing or eliminating IV amphotericn B.
Children- safety and efficacy in children have not been established.
Dosages/ Overdosage Etc:

Amphotericin B is fungistatic or fungicidal. It acts by binding to sterols in the fungal cell membrane with a resultant change in membrane permeability, allowing leakage of a variety of small molecules.
Penetration of the drug into inflamed pleural cavities and joints is good. The drug is slowly excreted by the kidneys with 2% to 5% as the biologically active form

Reports not available.
Pregnancy and lactation:
Adequate and well controlled studies have not been conducted, therfore use during pregnancy only if needed
Not known whether Amphotericin is excreted in breast milk. Consider discontinuing nursing or eliminating Amphotericin use.
Children: Safety and efficacy in children have not been established.
