Amphotericin B liposome for injection is not interchangeable or substitutable on a mg per mg basis with other amphotericin B products. Different amphotericin B products are not equivalent in terms of pharmacodynamics, pharmacokinetics and dosing. Amphotericin B liposome for injection should be administered by intravenous infusion, using a controlled infusion device, over a period of approximately 120 minutes. An in-line membrane filter may be used for the intravenous infusion of amphotericin B liposome for injection; provided THE MEAN PORE DIAMETER OF THE FILTER IS NOT LESS THAN 1.0 MICRON. NOTE: An existing intravenous line must be flushed with 5% Dextrose Injection prior to infusion of amphotericin B liposome for injection. If this is not feasible, amphotericin B liposome for injection must be administered through a separate line. Infusion time may be reduced to approximately 60 minutes in patients in whom the treatment is well-tolerated. If the patient experiences discomfort during infusion, the duration of infusion may be increased. The recommended initial dose of amphotericin B liposome for injection for each indication for adult and pediatric patients is as follows: Indication Dose (mg/kg/day) Empirical therapy 3 Systemic fungal infections: Aspergillus Candida Cryptococcus 3 to 5 Cryptococcal meningitis in HIV-infected patients (see DESCRIPTION OF CLINICAL STUDIES ) 6…
The following adverse events are based on the experience of 592 adult patients (295 treated with amphotericin B liposome for injection and 297 treated with amphotericin B deoxycholate) and 95 pediatric patients (48 treated with amphotericin B liposome for injection and 47 treated with amphotericin B deoxycholate) in Study 94-0-002, a randomized double-blind, multicenter study in febrile, neutropenic patients. Amphotericin B liposome for injection and amphotericin B were infused over two hours. The incidence of common adverse events (incidence of 10% or greater) occurring with amphotericin B liposome for injection compared to amphotericin B deoxycholate, regardless of relationship to study drug, is shown in the following table: Empirical Therapy Study 94-0-002 Common Adverse Events Adverse Event by Body System Amphotericin B Liposome for Injection N=343 % Amphotericin B N=344 % Body as a Whole Abdominal pain 19.8 21.8 Asthenia 13.1 10.8 Back pain 12 7.3 Blood product transfusion reaction 18.4 18.6 Chills 47.5 75.9 Infection 11.1 9.3 Pain 14 12.8 Sepsis 14 11.3 Cardiovascular System Chest pain 12 11.6 Hypertension 7.9 16.3 Hypotension 14.3 21.5 Tachycardia 13.4 20.9 Digestive System Diarrhea 30.3 27.3 Gastrointestinal hemorrhage 9.9 11.3 Nausea 39.7 38.7 Vomiting 31.8 43.9 Metabolic and Nutritional Disorders Alkaline phosphatase increased 22.2 19.2 ALT (SGPT) increased 14.6 14…

Amphotericin B liposome for injection is contraindicated in those patients who have demonstrated or have a known hypersensitivity to amphotericin B deoxycholate or any other constituents of the product unless, in the opinion of the treating physician, the benefit of therapy outweighs the risk.
No formal clinical studies of drug interactions have been conducted with amphotericin B liposome for injection. However, the following drugs are known to interact with amphotericin B and may interact with amphotericin B liposome for injection: Antineoplastic Agents Concurrent use of antineoplastic agents may enhance the potential for renal toxicity, bronchospasm, and hypotension. Antineoplastic agents should be given concomitantly with caution. Corticosteroids and Corticotropin (ACTH) Concurrent use of corticosteroids and ACTH may potentiate hypokalemia, which could predispose the patient to cardiac dysfunction. If used concomitantly, serum electrolytes and cardiac function should be closely monitored. Digitalis Glycosides Concurrent use may induce hypokalemia and may potentiate digitalis toxicity. When administered concomitantly, serum potassium levels should be closely monitored. Flucytosine Concurrent use of flucytosine may increase the toxicity of flucytosine by possibly increasing its cellular uptake and/or impairing its renal excretion. Azoles (e.g. ketoconazole, miconazole, clotrimazole, fluconazole, etc.) In vitro and in vivo animal studies of the combination of amphotericin B and imidazoles suggest that imidazoles may induce fungal resistance to amphotericin B. Combination therapy should be administered with caution, especially in immunocompromised…
