Doxorubicin hydrochloride liposome injection is doxorubicin hydrochloride, USP an anthracycline topoisomerase inhibitor, that is encapsulated in PEGYLATED liposomes for intravenous use. The chemical name of doxorubicin hydrochloride, USP is (8S,10S)-10-[(3-amino-2,3,6-trideoxy-α-L-lyxohexopyranosyl)oxy]-8-glycolyl-7,8,9,10-tetrahydro-6,8,11-trihydroxy-1-methoxy-5,12-naphthacenedione hydrochloride. The molecular formula is C 27 H 29 NO 11 •HCl; its molecular weight is 579.99. The structure formula is: Doxorubicin hydrochloride liposome injection is a sterile, translucent, red liposomal dispersion in 10-mL or 30-mL glass, single-dose vials. Each vial contains 20 mg or 50 mg doxorubicin hydrochloride, USP at a concentration of 2 mg/mL (equivalent to 1.87 mg/mL of doxorubicin) and a pH of 6.5. The PEGYLATED liposome carriers are composed of cholesterol, 3.19 mg/mL; fully hydrogenated soy phosphatidylcholine (HSPC), 9.58 mg/mL; and N-(carbonyl-methoxypolyethylene glycol 2000)-1,2-distearoyl-sn-glycero-3-phosphoethanolamine sodium salt (MPEG-DSPE), 3.19 mg/mL. Each mL also contains ammonium sulfate, approximately 0.6 mg; histidine 1.55 mg as a buffer; hydrochloric acid and/or sodium hydroxide for pH adjustment; and sucrose 94 mg to maintain isotonicity. Greater than 90% of the drug is encapsulated in the PEGYLATED liposomes. MPEG-DSPE has the following structural formula: n=ca. 45 HSPC has the following structural formula: m,n=14 or 16 Representation of a PEGYLATED liposome:
