RESUMEN

Objetivos:

Evaluar en mujeres chilenas, la eficacia, tolerabilidad y seguridad del anticonceptivo Belara® (Acetato de Clormadinona 2 mg y Etinilestradiol 0,03 mg) (ACM/EE).

Métodos:

Estudio no intervencional, multicéntrico, prospectivo, de 6 ciclos de seguimiento, evaluando efectividad anticonceptiva, estabilidad de ciclo, tolerabilidad, seguridad y acción sobre peso, piel y cabello.

Resultados:

ACM/EE fue tomado por 593 mujeres durante 3426 ciclos. Hubo 2 embarazos durante el seguimiento, uno voluntario y otro involuntario; en ninguno de los casos se consideró como falla del método. Durante el tratamiento se observó mejoría progresiva en la estabilidad del ciclo menstrual, sangrado intermenstrual, amenorrea y dismenorrea, con frecuencia de 4,5%, 1,4%, 2,5% y 11,6% al sexto ciclo, respectivamente. El porcentaje de mujeres con piel normal incrementó de 25,5% antes del tratamiento a 63,6% después de seis meses de administración continua de ACM/EE. El peso promedio se mantuvo estable durante el tratamiento. Los eventos adversos mas frecuentes fueron cefalea (10,4%), aumento de peso (8,3%), mastalgia (6,1%) y trastornos del ánimo (2%). El 11% de las usuarias (n=63) suspendió ACM/EE antes de terminar los 6 meses de observación. El 97,2% de los médicos y 96,1% de las usuarias calificaron los resultados con ACM/EE como “buenos o muy buenos”.

Conclusiones:

Similar a los resultados reportados en la literatura europea, este estudio realizado en población chilena, confirma la eficacia, seguridad y tolerabilidad de ACM/EE así como los beneficios antiandrogénicos adicionales sobre piel y cabello, y su efecto neutral sobre el peso corporal.
ABSTRACT

Objectives:

To evaluate 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, prospective, 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.
