Overview
11 DESCRIPTION IDAMYCIN PFS contains idarubicin hydrochloride, which is an anthracycline topoisomerase inhibitor. Chemically, idarubicin hydrochloride is 5, 12-Naphthacenedione, 9-acetyl-7-[(3-amino-2,3,6-trideoxy-α-L-lyxo-hexopyranosyl)oxy]-7,8,9,10-tetrahydro-6,9,11-trihydroxyhydrochloride, (7S- cis ). The structural formula is as follows: C 26 H 27 NO 9 ∙HCl M.W. 533.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Idarubicin hydrochloride has antimitotic and cytotoxic activity through forming complexes with the DNA, inhibiting nucleic acid synthesis, inhibiting topoisomerase II activity, and producing DNA-damaging free radicals. 12.2 Pharmacodynamics Idarubicin hydrochloride exposure-response relationships and the time course of pharmacodynamic response have not been fully characterized. 12.3 Pharmacokinetics Idarubicin hydrochloride pharmacokinetics were determined in adult leukemia patients with normal renal and hepatic function following intravenous administration of idarubicin hydrochloride 10 to 12 mg/m 2 daily for 3 to 4 days as a single agent or combined with cytarabine. Accumulation is predicted to be 1.
