Amphotericin B Liposome

What it is and how it works

Mechanism of Action Amphotericin B, the active ingredient of amphotericin B liposome for injection, acts by binding to the sterol component, ergosterol, of the cell membrane of susceptible fungi. It forms transmembrane channels leading to alterations in cell permeability through which monovalent ions (Na + , K + , H + , and Cl - ) leak out of the cell resulting in cell death. While amphotericin B has a higher affinity for the ergosterol component of the fungal cell membrane, it can also bind to the cholesterol component of the mammalian cell leading to cytotoxicity.

Indications

INDICATIONS AND USAGE Amphotericin B liposome for injection is indicated for the following: Empirical therapy for presumed fungal infection in febrile, neutropenic patients. Treatment of Cryptococcal Meningitis in HIV-infected patients (see DESCRIPTION OF CLINICAL STUDIES ). Treatment of patients with Aspergillus species, Candida species and/or Cryptococcus species infections (see above for the treatment of Cryptococcal Meningitis) refractory to amphotericin B deoxycholate, or in patients where renal impairment or unacceptable toxicity precludes the use of amphotericin B deoxycholate. Treatment of visceral leishmaniasis. In immunocompromised patients with visceral leishmaniasis treated with amphotericin B liposome for injection, relapse rates were high following initial clearance of parasites (see DESCRIPTION OF CLINICAL STUDIES ). See DOSAGE AND ADMINISTRATION for recommended doses by indication. DESCRIPTION OF CLINICAL STUDIES Eleven clinical studies supporting the efficacy and safety of amphotericin B liposome for injection were conducted.

Dosage and administration (summary)

DOSAGE AND ADMINISTRATION 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 MICRON.

Contraindications

CONTRAINDICATIONS 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.

Warnings and precautions

WARNINGS Anaphylaxis has been reported with amphotericin B deoxycholate and other amphotericin B-containing drugs, including amphotericin B liposome for injection. If a severe anaphylactic reaction occurs, the infusion should be immediately discontinued and the patient should not receive further infusions of amphotericin B liposome for injection.

Pregnancy

Pregnancy There have been no adequate and well-controlled studies of amphotericin B liposome for injection in pregnant women. Systemic fungal infections have been successfully treated in pregnant women with amphotericin B deoxycholate, but the number of cases reported has been small.
