Drugs that have an influence on the induction of enzymes that metabolize estrogens, reduce the contraceptive effectiveness of hormonal drugs. There is a chance that these same isozymes can lead to a decrease in progestogen component in the blood concentration. Clinically relevant in this respect are drugs and herbal remedies that affect the enzymes involved in the biological transformation of contraceptive steroid hormones such as:
- St. John’s Wort;
- pyrazolone derivatives;
It has been explored that some protease inhibitors and some antiretroviral drugs increase (for example, indinavir) or reduce (for example, ritonavir) the concentration of combined hormonal contraceptives.
Another type of interaction includes the violation of intrahepatic circulation of estrogens, as a result of which the excretion is accelerated and the concentration of ethinyl estradiol is decreased.
