BACKGROUND: This study investigated the effects of the low-dose combined oral contraceptive (COC) 2.0 mg chlormadinone acetate (CMA)/0.03 mg ethinylestradiol (EE) (Belara, Balanca) on cycle-related physical and emotional disorders in women >or=25 years of age.
STUDY DESIGN: A prospective, non-interventional, observational study of 3772 women over six cycles was conducted in 303 office-based gynecological centers throughout Germany.
RESULTS: CMA/EE provided high contraceptive efficacy with a Pearl index of 0 (95% confidence interval=0.00-0.22) and was generally well tolerated, with no statistically significant weight changes during the observation period (p=.147). CMA/EE intake resulted in a statistically significant improvement in cycle-related physical and emotional symptoms, with a 67% overall reduction in sum score for number and intensity of cycle-related symptoms per patient.
CONCLUSIONS: The results of this study in women >or=25 years of age support previous findings that 2.0 mg CMA/0.03 mg EE is an effective low-dose COC, with an excellent tolerability profile, with the additional benefits of significantly reducing both cycle-related physical and emotional symptoms (p<or=.001); women with the respective preexisting symptoms may, therefore, benefit from CMA/EE contraceptive treatment. Further research is warranted.
