The effect of cyclohexylamine on the embryo following oral administration to mice and rats.
The possible embryotoxic effects of cyclohexylamine hydrochloride doses (expressed as free base) of 10, 30 and 100 mg/kg of body weight per day administered orally in water to mice and rats from the 6th to 15th day post-coitum were investigated. Treatment with daily doses of up to 100 mg/kg of body weight to mice and of up to 30 mg/kg to rats had no adverse effect on the mothers and the embryos. In the rat the dose of 100 mg/kg led to decreased weight gain in the mothers during the treatment period. In parallel, a non-specific retardation of the embryo was found, since the weight of the foetus and of the placenta were significantly reduced. Cyclohexylamine had neither a teratogenic effect nor a primary toxic effect on the embryo in either of the animal species. The tolerated dose without any harm for the development of the embryo was 100 mg/kg/day in mice and 30 mg/kg/day in rats.
