WebPharmacokinetics. Norethisterone is rapidly absorbed and reaches maximum plasma concentration after 1-2 hours. Plasma protein binding is 99%. Metabolism occurs in the liver by the enzymes α- and 3β-hydroxysteroid dehydrogenase and 5α- and 5β-reductase and also to some extent by the enzymes of the CYP450 system.
