Pipoxolan (HCl) is an antispasmodic drug. In vivo, the drug inhibited the contractions of intestines caused by neostigmine, barium chloride or injection of acetylcholine. The drug possesses ganglioplegic action and inhibited the decrease in blood pressure caused by stimulation of the vagus nerve. The drug is marketed under tradename Rowapraxin worldwide for the treatment of spasms and colics in the gastrointestinal tract, gallbladder and urogenital area, bronchial spasms, spastic menstrual cramps. Recent studies have shown that pipoxalan has anticancer activity and inhibits proliferation of leukemia cells in animal models.
