title: 1-month subacute oral toxicity study of KB-944, a new calcium antagonist, in beagles.
abstract: Using male and female Beagles, we studied the subacute toxicity of diethyl 4-(benzothiazol-2-yl)benzylphosphonate (KB-944) administered orally and the following results were obtained. No dogs died during the administration period. Both male and female dogs given 200 mg/kg and those given 100 mg/kg underwent body weight decrease and inhibition of body weight increase, respectively. Enlargement of liver cells occurred in male dogs given 200 mg/kg and female dogs given 100 or 200 mg/kg. There were no further findings, even histopathologically, which showed any toxic effect of the drug. The maximum non-toxic dose of this drug was considered to be 30 mg/kg.
