AMOSENE vs LEVONORGESTREL AND ETHINYL ESTRADIOL AND FERROUS FUMARATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amosene is a benzodiazepine that enhances gamma-aminobutyric acid (GABA) activity at GABA-A receptors, increasing chloride ion conductance and neuronal hyperpolarization, leading to anxiolytic, sedative, and muscle relaxant effects.
Combination hormonal contraceptive. Ethinyl estradiol and levonorgestrel inhibit gonadotropin release (FSH, LH), suppressing ovulation. Progestin effect: thickens cervical mucus, alters endometrial receptivity. Ferrous fumarate provides iron supplementation during placebo phase.
400 mg orally twice daily for 14 days
One tablet (0.15 mg levonorgestrel, 0.03 mg ethinyl estradiol, 75 mg ferrous fumarate) orally once daily at the same time for 21 consecutive days, followed by one ferrous fumarate-only tablet (75 mg) orally once daily for 7 days (28-day cycle).

Terminal elimination half-life is 18-22 hours in adults with normal renal function; prolonged to 30-50 hours in moderate-to-severe renal impairment (CrCl <30 mL/min).
Levonorgestrel: ~25 hours, steady-state after 5 days. Ethinyl estradiol: ~13 hours (7–20). Ferrous fumarate: not applicable.
Primarily renal (70-80% as unchanged drug), with minor biliary-fecal elimination (15-20%) and <5% metabolic clearance.
Levonorgestrel: ~45% renal, ~32% fecal. Ethinyl estradiol: ~40% renal, ~60% fecal. Ferrous fumarate: iron excreted in feces as unabsorbed; minimal renal.
