Desogestrel is a synthetic progestogen (progestin) used mainly as a hormonal contraceptive in oral tablets, either alone or combined with ethinyl estradiol. It is a third-generation progestin and is currently approved for use in many countries for female contraception.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult women (aged 18-35), receiving an oral dose of desogestrel as part of contraceptive regimen.
