MARQIBO KIT vs MATULANE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vinca alkaloid that binds to tubulin, inhibiting microtubule assembly and mitotic spindle formation, causing metaphase arrest in dividing cells.
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.
2.25 mg/m2 intravenously over 1 hour every 7 days. Maximum dose per administration is 3.6 mg.
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.

Terminal elimination half-life ranges from 19 to 40 hours (mean 23 hours) in adults. The prolonged half-life in Marqibo (liposomal vincristine) is due to the sustained release from the liposomal formulation, allowing once-weekly dosing.
Terminal elimination half-life is approximately 7-10 hours (range 5-15 hours) in adults; context: prolonged in hepatic or renal impairment.
Primarily hepatobiliary excretion; approximately 5-16% of the dose is excreted unchanged in the urine over 72 hours. Fecal excretion accounts for about 10% of the administered dose, with the remainder undergoing extensive hepatic metabolism and biliary elimination.
Primarily renal (approximately 50-60% as unchanged drug and metabolites) and fecal (approximately 10-20%); minor biliary excretion.
