Pharmacokinetics Three Mercy
Desogestrel, when taken orally, is completely and rapidly absorbed with subsequent conversion into etonogestrel. Etonogestrel binds to globulin, which binds sex hormones. The bioavailability of the drug is 62-81%.
The drug is completely metabolized by the pathways of steroid hormone metabolism. An interaction between concomitantly taken etonogestrel and ethinyl estradiol was not found. The final half-life of the drug occurs after 30 hours. The drug and its metabolites are excreted in urine and bile, in a ratio of 6: 4.
Globulin, which binds sex hormones, affects the pharmacokinetics of desogestrel. Daily intake leads to an increase in the level of the drug in the blood plasma, by 2-3 times.
Ethinyl estradiol, when taken orally, is completely and rapidly absorbed. Bioavailability, as a result of metabolism and presystemic conjugation, with primary passage through the liver, is approximately 60%.
The concentration of ethinyl estradiol in the blood decreases in two stages. The final stage is characterized by a half-life of the Three Mercy in about a day.
A stable level of drug concentration is achieved after 3-4 days of regular use.
