FIXED PROLONGED REGIME OF COMBINED ORAL CONTRACEPTIVES (COC) INTAKE IN SOLUTION OF CLASSIC CONTRACEPTION ISSUES (LITERATURE REVIEW)

Abstract

Combined oral contraceptives (COC) – the most popular reversible method to prevent unwanted pregnancy used in the whole world. The popularity of COC remains unchanged since the moment of their appearance [1]. Thus, in the US COC are used by each 4 out of 5 women using combined hormonal contraceptives [2]. In Russia the whole diversity is available now: of various dosage forms of hormonal contraceptives (tablets, vaginal rings, patches, implants, intrauterine hormonal releasing systems), and of formulations (use of ethinyl estradiol and estrogens analogous to natural ones, use of progestogens of all types) and intake regimes as well (one-time and urgent, daily, monthly, for several years) that allows the doctor in cooperation with the female patient to conduct the informed choice of the most optimal method of contraception. But in Russia the situation that is extremely untypical for other countries remains. On the one hand, complete availability of hormonal contraceptives, on the other hand, the degree of their use and indication remains on the sufficiently low level.
