Bioavailability of norethindrone in human subjects

European Journal of Clinical Pharmacology, 1978
A competitive protein binding assay for norethindrone was developed to measure plasma levels in human subjects. The plasma levels were considerably higher in women than in men, especially at low dose levels. The plasma levels were directly related to the dose in men; but greater variations in the plasma levels were observed in women.

Pharmacokinetics of norethindrone acetate in women

American Journal of Obstetrics and Gynecology, 1979
The plasma half-life, MCR and plasma metabolite levels at various time intervals have been studied in six women after an intravenous injection of 3H-norethindrone acetate. The disappearance curve due to norethindrone acetate showed an initial rapid disappearance of 3H with an average half-life of 7.5 minutes and a subsequent slow disapperance with a ...

Norethindrone in Serum After use of an oral Contraceptive Containing Norethindrone Acetate

Acta Obstetricia et Gynecologica Scandinavica, 1983
Abstract. The availability of norethindrone (NET) in serum was studied in 8 women after daily administration of a combination oral contraceptive pill (MinovlarR) containing 1 mg norethindrone acetate (NETA) and 50 μg ethinyl estradiol (EE2) from day 5 to day 25 of the menstrual cycle. The pill was taken daily at 9.30 a.m.

Plasma levels of norethindrone after I.M. injection of 200 mg norethindrone enanthate

Contraception, 1975
Abstract The plasma levels of norethindrone were measured with a radioimmunoassay after an intramuscular injection of 200 mg of norethindrone enanthate in five healthy women. After an initial peak of norethindrone between 8–14.5 ng/ml, a gradual decline followed. The concentration of 1 ng/ml was reached after approximately 45 days. The plasma pattern
