Information

A combined hormone therapy used primarily for menopausal hormone replacement in women, usually containing medroxyprogesterone acetate and an estrogen (commonly conjugated estrogens or estradiol). Used to treat symptoms associated with menopause such as hot flashes and to prevent osteoporosis. Although still in use, its prescription has declined due to concerns over long-term safety, particularly thromboembolic and cancer risks.

Pharmacokinetics

No published pharmacokinetic models for the fixed combination under ATC G03FB06 have been found. Parameter estimates are inferred based on data for individual components (oral medroxyprogesterone acetate and oral estradiol/conjugated estrogen) in healthy adult women.
