The fixed-dose combination of progesterone and estrogen (with ATC code G03FA04) is used in hormone replacement therapy, particularly for menopausal symptoms such as hot flashes and osteoporosis prevention. It is an approved medication in several countries and is mostly administered orally.
Pharmacokinetics
Pharmacokinetic parameters are estimated for a typical healthy adult female population receiving oral administration, as no published studies have specifically reported full model parameters for this fixed combination.
