SCHILLING R, Andrea. EXPERIENCIA CHILENA CON EL USO DE UN ANTICONCEPTIVO ORAL COMBINADO DE ACETATO DE CLORMADINONA/ETINILESTRADIOL: ESTUDIO NO INTERVENCIONAL. Rev. chil. obstet. ginecol. [online]. 2008, vol.73, n.5, pp.293-298. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262008000500002.

Objectives: To evalúate the efficacy, tolerability and safety of the contraceptive Belara® (chlormadinone 2 mg/ethinylestradiol 0.03 mg; ACM/EE) in chilean women. Methods: Non interventional, multicentric, pros-pective, 6 cycles follow up trial, evaluating contraceptive efficacy, cycle stability, tolerability, safety, and effect on hair and skin. Results: AMC/EE was taken by 593 women for a total of 3426 cycles. Two pregnancies were reported during follow-up, one voluntary and the other involuntary; they were not considered failure of the method. Progressive improvement in cycle stability, intermenstrual bleeding, amenorrhea and dysmenorrhea occurred during the treatment period reaching 4.5%, 1.4%, 2.5% y 11.6% at the 6th cycle respectively. The percentage of women with normal skin increased from 25.5% prior to treatment, to 63.6%, after taking ACM/EE during six months. The average body weight was maintained throughout treatment. The most frequent adverse events were: headache (10.4%), weight increase (8.3%), breast tenderness (6.1 %) and mood changes (2%). An 11 % of users (n=63) discontinued the use of ACM/EE before completing the observational period of six months. A 97.2% of physicians and 96.1% of users qualified the results with ACM/EE as "good or very good". Conclusions: Similar to the results reported in the European literature, this study in the Chilean population confirmed the efficacy, safety and tolerability of ACM/EE, together with its antiandrogenic benefits on skin and hair, and its neutral effect on body weight.
