BACKGROUND
This prospective noninterventional study assessed the contraceptive efficacy, safety and the effects on signs of androgenization of the generic oral contraceptive containing 2 mg chlormadinone acetate/0.03 mg ethinylestradiol (CMA/EE) in a real-world setting.
METHODS
A total of 1440 women were investigated during a six-cycle period by 229 gynecological practices throughout Germany.
RESULTS
The adjusted Pearl index was 0.136 (unadjusted: 0.271). Of 463 patients with cycle irregularities at baseline, 83.4% had regular cycles after six cycles. Likewise, 74.1% of 162 patients with spotting or breakthrough bleeding at baseline were free from these symptoms at the end of study. The percentage of patients with dysmenorrhea decreased significantly from baseline (36.5%) to visit 3 after six cycles (12.3%; p=.0001), with a significant reduction in the use of pain medication (p<.0001). Additionally, the number of patients with skin and hair problems was significantly reduced (skin: 56.3% at baseline, 19.6% after six cycles; hair: 45.7% at baseline, 13.4% after six cycles; p=.001). CMA/EE was well tolerated by the patients, and 89.44% of the gynecologists were satisfied with the treatment.
CONCLUSIONS
Generic CMA/EE exhibits very good contraceptive efficacy, cycle control and dysmenorrhea reduction. Furthermore, treatment with generic CMA/EE led to a favorable reduction of skin and hair problems in our study.
