[The effect of diethylnicotinamide (cordiamine) on the activity of the hydroxylating and glucuronyl-conjugating systems in humans].

Administration of diethylnicotinamide (250 mg orally three times for 8 days) to healthy subjects increased antipyrine (AP) elimination from the saliva by 23% and decreased its half-life by 26%. The excretion in the urine of the products of AP hydroxylation 3-carboxymethylantipyrine and nor-antipyrine as well as glucuronides 3-hydroxymethylantipyrine increased. A positive correlation between the dynamics of the excretion of antipyrine metabolites and glucuronic acid was observed. The elimination from blood of bilirubin glucuronides increased. Diethylnicotinamide in therapeutic doses is supposed to stimulate the processes of hydroxylation and glucuronyl conjugation in humans.
