Pharmacokinetics Clinical Trial
Official title:
Open Label, One-way Crossover Study to Assess the in Vivo Formation of Ethinylestradiol Following Single Intramuscular Administration of 200 mg Norethisterone Enantate Compared to Ethinylestradiol Pharmacokinetics After Multiple Doses of a Combined Oral Contraceptive Containing Ethinylestradiol and Levonorgestrel in Healthy Premenopausal Women
The clinical phase I study aims at investigating the conversion of the contraceptive compound norethisterone within the body towards the contraceptive compound ethinylestradiol. Therefore concentrations of ethinylestradiol will be measured from blood samples after administration of a single intramuscular dose of norethisterone. In a comparison arm concentrations of ethinylestradiol will be measured from blood samples after administration of a pill containing ethinylestradiol itself.
