Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination hormonal contraceptive. Norethindrone acetate suppresses gonadotropin release (FSH and LH) via progestogenic activity, inhibiting ovulation. Ethinyl estradiol provides negative feedback on hypothalamic-pituitary axis, further suppressing gonadotropins and stabilizing endometrium.
ENSKYCE (fospropofol disodium) is a prodrug of propofol. It is hydrolyzed by alkaline phosphatases to release propofol, which acts as a positive allosteric modulator of GABA-A receptors, enhancing chloride conductance and producing sedation and anesthesia.
One tablet (0.10 mg ethinyl estradiol / 1.0 mg norethindrone acetate) orally once daily for 24 days, followed by 4 days of ferrous fumarate 75 mg tablets (placebo). Administer at the same time each day without interruption.
2 g IV every 8 hours over 5 hours on days 1-3 of each 21-day cycle

Norethindrone: 7-8 hours; Ethinyl estradiol: 13-16 hours. Steady-state achieved within 5 days.
12 hours (terminal); allows once-daily dosing in most patients
Norethindrone: ~40% renal, ~60% fecal; Ethinyl estradiol: ~40% renal, ~60% fecal as glucuronide and sulfate conjugates.
Renal: ~70% unchanged; Biliary/Fecal: ~20% as metabolites
