The intestinal absorption and excretion of 14C drotaverin in rats. 1979

G Simon, and Z Vargay, and M Winter, and T Szüts

The absorption and biliary excretion of drotaverin/a papaverine analogue/were studied in rats. In vivo loop technique was used. The absorption of the compounds from the jejunum was found to be rapid and the activity injected into the duodenal sac to disappear only when the common bile duct was ligated. An appreciable activity was detected in the bile collected by cannulation following both i.v. (67%) or per os (31%) administration. Considerable activity was excreted with the bile even 24 hours after drug administration. A partial entero-hepatic cycle for the drotaverin metabolites is suggested.

D010208 Papaverine An alkaloid found in opium but not closely related to the other opium alkaloids in its structure or pharmacological actions. It is a direct-acting smooth muscle relaxant used in the treatment of impotence and as a vasodilator, especially for cerebral vasodilation. The mechanism of its pharmacological actions is not clear, but it apparently can inhibit phosphodiesterases and it may have direct actions on calcium channels.
