MATULANE vs NELARABINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Matulane (procarbazine) is a prodrug that undergoes metabolic activation to generate cytotoxic alkylating metabolites. It inhibits DNA, RNA, and protein synthesis through methylation of nucleic acids and proteins, and may also inhibit monoamine oxidase.
Nelarabine is a prodrug of ara-G, a deoxyguanosine analog. It is converted to ara-GTP, which accumulates in T-cells and inhibits DNA synthesis, leading to cell death.
200-300 mg orally once daily for 10-14 days as part of MOPP regimen; maintenance dose: 50-100 mg orally once daily after hematologic recovery.
1500 mg/m2 intravenously over 2 hours on days 1, 3, and 5, repeated every 28 days.

Terminal elimination half-life is approximately 7-10 hours (range 5-15 hours) in adults; context: prolonged in hepatic or renal impairment.
Terminal t1/2: 30 hours (range 21-48 h) in adults; prolonged in renal impairment. Ara-G (active metabolite) t1/2: 3 hours.
Primarily renal (approximately 50-60% as unchanged drug and metabolites) and fecal (approximately 10-20%); minor biliary excretion.
Renal: 50-60% as unchanged ara-G; fecal: <5% as metabolites; biliary: negligible.
