ENSKYCE vs TRI-ESTARYLLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Combination hormonal contraceptive containing ethinyl estradiol and drospirenone. Ethinyl estradiol suppresses gonadotropin release, inhibiting ovulation. Drospirenone is a spironolactone analogue with anti-mineralocorticoid and antiandrogenic activity, also suppressing ovulation and increasing cervical mucus viscosity.
2 g IV every 8 hours over 5 hours on days 1-3 of each 21-day cycle
One tablet (ethinyl estradiol 0.03 mg / norgestimate 0.18-0.215-0.25 mg) orally once daily for 21 days followed by 7 placebo days.

12 hours (terminal); allows once-daily dosing in most patients
Terminal elimination half-life is 4-6 hours; clinical context: allows twice-daily dosing for stable blood levels.
Renal: ~70% unchanged; Biliary/Fecal: ~20% as metabolites
Renal: approximately 60% as unchanged drug and metabolites; Biliary/fecal: approximately 40%, primarily as metabolites.
