INCASSIA vs LUNELLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
INCASSIA (bleomycin) is an antineoplastic antibiotic that causes DNA strand breaks through free radical generation, inhibiting DNA synthesis and cell division.
Lunelle is a combination contraceptive injection containing medroxyprogesterone acetate and estradiol cypionate. It suppresses gonadotropin secretion, inhibiting ovulation and thickening cervical mucus to prevent sperm penetration.
1.5 mg orally once daily, administered with or without food.
150 mg intramuscular injection on day 5 of menstrual cycle, then every 90 days thereafter.

Terminal elimination half-life is 8-12 hours in adults with normal renal function. This supports twice-daily dosing, though dose adjustment is required in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life of 20-30 hours in healthy adults; prolonged to 40-60 hours in moderate renal impairment (CrCl 30-50 mL/min). Clinically, steady state reached in 4-5 days.
Renal excretion of unchanged drug accounts for approximately 60-70% of the administered dose, with biliary/fecal elimination contributing about 20-30%. Less than 10% is metabolized.
Primarily renal (~70% as unchanged drug and inactive metabolites), with ~20% biliary/fecal elimination. Minimal dose recovered in feces as parent compound.
