The active ingredient in doxorubicin hydrochloride liposome injection is doxorubicin hydrochloride, an anthracycline topoisomerase inhibitor, that is encapsulated in pegylated liposomes for intravenous use. The chemical name of doxorubicin hydrochloride is (8S,10S)-10-[(3-amino-2,3,6-trideoxy-α-L-lyxo-hexopyranosyl)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 structural formula is: Doxorubicin hydrochloride liposome injection is a sterile, translucent, red liposomal dispersion. Each single-dose 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, 1.50 mg as a buffer; hydrochloric acid and/or sodium hydroxide for pH control; and sucrose, 100 mg to maintain isotonicity. Greater than 90% of the drug is encapsulated in the pegylated liposomes. spl-doxorubicin-structure spl-doxorubicin-structure1 spl-doxorubicin-structure2 spl-doxorubicin-figure
