Levonorgestrel and estrogen are used in combination as oral contraceptives for the prevention of pregnancy. The combination is widely used and approved for contraceptive purposes in many countries. Levonorgestrel is a synthetic progestogen, while estrogen (usually ethinylestradiol) is a synthetic estrogen component.
Pharmacokinetic parameters are estimated for a typical healthy adult non-pregnant female, population for oral combined hormonal contraceptive use. No direct reference describing full compartmental PK parameters for the specific combination with ATC code G03FB09 was found.
