GLEOSTINE vs TEPYLUTE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GLEOSTINE (lomustine) is a nitrosourea alkylating agent that crosslinks DNA and RNA, inhibiting DNA synthesis and repair. It is cell cycle phase-nonspecific.
Progestin that transforms endometrium from proliferative to secretory phase, inhibits gonadotropin secretion, and increases cervical mucus viscosity.
130 mg/m2 orally every 6 weeks as a single dose; alternatively, 75 mg/m2 orally every 3 weeks.
100 mg orally once daily

16-48 hours (terminal), with an active metabolite half-life of up to 5 days, requiring dose adjustment for renal impairment
Terminal elimination half-life is 4-6 hours in healthy adults; prolonged to 10-15 hours in severe renal impairment.
Renal: 60% (as metabolites), Fecal: <5% (unchanged and metabolites), Biliary: minimal
Primarily renal (70-80% unchanged) and fecal (15-20% as metabolites).
