The active ingredient in DOXIL liposomal infusion is doxorubicin hydrochloride, an anthracycline topoisomerase inhibitor, that is encapsulated in STEALTH 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 C27-H29 -NO11•HCl and the molecular weight is 579.99. The structural formula is: DOXIL liposomal infusion is a sterile, translucent, red liposomal dispersion. Each single-dose vial contains 20 mg or 50 mg doxorubicin hydrochloride at a concentration of 2 mg/mL (equivalent to 1.87 mg/mL of doxorubicin). The STEALTH 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 may have been added for pH adjustment (6.0 to 7.0); and sucrose, 94 mg to maintain isotonicity. Greater than 90% of the drug is encapsulated in the STEALTH liposomes. MPEG-DSPE has the following structural formula: HSPC has the following structural formula: Representation of a STEALTH liposome: image-01-doxil-structural-formula image-02-mpge-dspe-structural-formula image-03-hspc-structural-formula image-04-stealth-liposome
