Description
Norethindrone is a synthetic progestin which in low doses is progestational and in high doses is antiestrogenic. Norethindrone also causes a time-dependent loss of cytochrome P-450 when incubated in vitro with rat liver microsomal fractions in NADPH-generating systems.More related product prices
