Carcinogenesis, Mutagenesis, Impairment of Fertility

Chronic oral toxicity studies in rats and mice, employing dose levels as high as 300 mg/kg/day, which is equivalent to 15 times the maximum recommended (60 kg) human dose, did not indicate a carcinogenic potential for Sectral. Diacetolol, the major metabolite of Sectral in man, was without carcinogenic potential in rats when tested at doses as high as 1800 mg/kg/day. Sectral and diacetolol were also shown to be devoid of mutagenic potential in the Ames Test. Sectral, administered orally to two generations of male and female rats at doses of up to 240 mg/kg/day (equivalent to 12 times the maximum recommended therapeutic dose in a 60-kg human) and diacetolol, administered to two generations of male and female rats at doses of up to 1000 mg/kg/day, had no significant impact on reproductive performance or fertility.
