Estradiol-containing birth control pill

Birth control pills containing estradiol have less impact on liver protein synthesis than ethinylestradiol-containing birth control pills, and it is thought that for this reason, they may pose less of a risk of venous thromboembolism (VTE). The risk of VTE with estradiol/nomegestrol acetate birth control pills is under study. Incidence of irregular vaginal bleeding may be higher with estradiol-containing birth control pills in relation to the fact that estradiol is a weaker estrogen than ethinylestradiol in the endometrium. ==Pharmacology==
