Documented Uses

A vasodilator used for treatment of hypertension (also as the hydrochloride which is soluble in water).
Pharmaceuticals -> Animal Drugs -> Approved in Taiwan
Papaverine was synthesized via the Bischler-Napieralski reaction as follows: the Schotten-Baumann reaction between the phenethylamine and the acyl chloride gave the amide. Cyclization with phosphorous pentoxide afforded the 3,4-dihydroisoquinoline. Mild dehydrogenation of /3,4-dihydroisoquinoline/ gave papaverine.
For the treatment of impotence and vasospasms.
Breast Feeding; Lactation; Milk, Human; Phosphodiesterase Inhibitors; Vasodilator Agents; Urological Agents
