Storage
Storage Prior to reconstitution Amphotericin B for Injection USP should be stored under refrigeration, 2˚ to 8˚C (36˚to 46˚F), protected against exposure to light. The concentrate (5 mg amphotericin B per mL after reconstitution with 10 mL Sterile Water for Injection USP) may be stored in the dark, at room temperature for 24 hours, or at refrigerator temperatures for one week with minimal loss of potency and clarity. Any unused material should then be discarded. Solutions prepared for intravenous infusion (0.1 mg or less amphotericin B per mL) should be used promptly after preparation and should be protected from light during administration.

DESCRIPTION Amphotericin B liposome for injection is a sterile, non-pyrogenic lyophilized product for intravenous infusion. Each vial contains amphotericin B, USP 50 milligrams (mg), intercalated into a liposomal membrane consisting of alpha tocopherol approximately 0.64 mg; cholesterol 52 mg; distearoylphosphatidylglycerol, sodium salt 84 mg; hydrogenated soy phosphatidylcholine 213 mg, together with disodium succinate hexahydrate 27 mg; and sucrose 900 mg. Amphotericin B liposome for injection may also contain hydrochloric acid and/or sodium hydroxide as pH adjusters. Following reconstitution with Sterile Water for Injection, the resulting pH of the suspension is between 5.0 to 6.0. Amphotericin B liposome for injection is a true single bilayer liposomal drug delivery system. Liposomes are closed, spherical vesicles created by mixing specific proportions of amphophilic substances such as phospholipids and cholesterol so that they arrange themselves into multiple concentric bilayer membranes when hydrated in aqueous solutions. Single bilayer liposomes are then formed by microemulsification of multilamellar vesicles using a homogenizer. Amphotericin B liposome for injection consists of these unilamellar bilayer liposomes with amphotericin B intercalated within the membrane. Due to the nature and quantity of amphophilic substances used, and the lipophilic moiety in the amphotericin B molecule, the drug is an integral part of the overall structure of the Amphotericin B liposomes. Amphotericin B liposome for injection contains true liposomes that are less than 100 nm in diameter. A schematic depiction of the liposome is presented below. Note: Liposomal encapsulation or incorporation into a lipid complex can substantially affect a drug’s functional properties relative to those of the unencapsulated drug or non-lipid associated drug. In addition, different liposomal or lipid-complex products with a common active ingredient may vary from one another in the chemical composition and physical form of the lipid component. Such differences may affect the functional properties of these drug products. Amphotericin B is a macrocyclic, polyene, antifungal antibiotic produced from a strain of Streptomyces nodosus . Amphotericin B is designated chemically as: [1R-(1R*,3S*,5R*,6R*,9R*,11R*,15S*,16R*,17R*,18S*, 19E,21E,23E,25E,27E,29E,31E,33R*,35S*,36R*,37S*)]-33-[(3-Amino-3,6-dideoxy-ß-D-mannopyranosyl)oxy]-1,3,5,6,9,11,17,37-octahydroxy-15,16,18-trimethyl-13-oxo-14,39-dioxabicyclo-[33.3.1]nonatriaconta-19,21,23,25,27,29,31-heptaene-36-carboxylic acid (CAS No.1397-89-3). Amphotericin B has a molecular formula of C 47 H 73 NO 17 and a molecular weight of 924.09 g/mol. The structure of amphotericin B is shown below: spl-ampho-lipo-structure spl-amphotercin-structure
⚠️ Warnings
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.
