ENSKYCE vs JUNEL FE 1/20
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 of ethinyl estradiol and norethindrone suppresses gonadotropin-releasing hormone (GnRH) from the hypothalamus, reducing luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion from the pituitary, thereby inhibiting ovulation. Additionally, induces changes in cervical mucus and endometrium to impede sperm penetration and implantation.
2 g IV every 8 hours over 5 hours on days 1-3 of each 21-day cycle
One tablet orally once daily for 21 days, followed by 7 days of placebo tablets. Each active tablet contains 1 mg norethindrone acetate and 20 mcg ethinyl estradiol.

12 hours (terminal); allows once-daily dosing in most patients
Ethinyl estradiol: 13-27 hours (terminal); norethindrone: 5-14 hours (terminal). Clinically, steady-state is achieved within 5-6 days.
Renal: ~70% unchanged; Biliary/Fecal: ~20% as metabolites
Renal (primarily as metabolites; ~50-60% of dose), fecal (~30-40% of dose). Unchanged drug excretion is minimal.
