AGRYLIN vs MATULANE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agrylin (anagrelide) inhibits cyclic nucleotide phosphodiesterase III (PDE3) and reduces platelet production by interfering with megakaryocyte maturation and proliferation, likely via inhibition of cyclic AMP phosphodiesterase and modulation of intracellular calcium levels.
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.
Adults: 0.5 mg orally once or twice daily, increased by 0.5 mg every 2 weeks to maintain platelet count <600,000/µL. Maximum dose: 10 mg/day.
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: 1.3–1.5 days (31–36 hours) in patients with ET; allows twice-daily dosing.
Terminal elimination half-life is approximately 7-10 hours (range 5-15 hours) in adults; context: prolonged in hepatic or renal impairment.
Renal: 80% (primarily unchanged drug), Biliary/Fecal: 5%
Primarily renal (approximately 50-60% as unchanged drug and metabolites) and fecal (approximately 10-20%); minor biliary excretion.
