What are the hormones used and the presentation form of the vaginal contraceptive ring?
The vaginal ring is a combined hormonal contraceptive consisting of a flexible and transparent ring made of evatane, containing 2.7 mg of ethinyl estradiol and 11.7 mg of etonogestrel.
The ring should be placed by the patient between the first and fifth day of the menstrual cycle, and each ring should be used for a cycle of 21 days, with a daily release of 120 mcg of etonogestrel and 15 mcg of ethinyl estradiol during three weeks.
The main mechanism of action of the vaginal ring is the inhibition of ovulation, and a secondary mechanism is the alteration of cervical mucus, which becomes thicker and unfavorable to sperm penetration.
The vaginal ring presents high efficacy in inhibiting ovulation, similar to the combined oral hormonal contraceptive, with a Pearl index for perfect use of 0.64.
