Phenobarbital (50 mg/kg) and benzonal (35 mg/kg) orally for 4 days and 3-methylcholanthrene (20 mg/kg) subcutaneously increased the excretion and tubular maximal transport of cardiotrast (diodrast) in rats. The inductors of the monooxigenase system seem to stimulate the renal transport of xenobiotics.
