Evaluation of genotoxic potential of synthetic progestin chlormadinone acetate.

The genotoxicity study of a synthetic progestin chlormadinone acetate, was carried out on mouse bone marrow cells using sister chromatid exchanges (SCEs) and chromosomal aberrations (CAs) as parameter, chlormadinone acetate was studied at three different doses, i.e. 5.62, 11.25 and 22.50 mg/kg body weight and was found to be non-genotoxic at 5.62 mg/kg body weight. But at 11.25 and 22.50 mg/kg of body weight chlormadinone acetate increases SCE (P < 0.001) and CA (P < 0.01) at significant level compared to normal control. The results suggests a genotoxic and cytotoxic effect of chlormadinone acetate in mouse bone marrow cells.
