What is L-Hydroxyproline?
Levonorgestrel exhibits some androgenic activity but no glucocortic oid or antimineraloc orticoid action. Levonorgestrel can be administered orally, transdermally (combined with estradiol and formulated as a 7-day patch), and for prolonged, continuous use, via an intrauterine device (IUD). The oral bioavailability of levonorgestrel is approximately 95%. From a protein binding pers pective, 48% of an oral dose is bound to SHBG, and 50% is bound to albumin. Levonorgestrel under goes metabolic reduction of its ketone and is hydroxylated.

Levonorgestrel is used in emergency contraceptive pills(ECPs), both in a combined Yuzpe regimenwhich includes estrogen, and as a levonorgestrel-only method.

Levonorgestrel is a synthetic progestin that binds to progesterone and androgen receptors but not the estrogen receptor. Induces apoptosis in ovarian epithelium cells.
