1. It has an adrenolytic, antihistaminic papaverine-like vasodilator action.

2. Musculotropic Antispasmodics, including papaverine and drotav-erinum, directly act on the smooth muscles

3. Musculotropic Antispasmodics, including papaverine and drotav-erinum, directly act on the smooth muscles

4. The results were: phencarbamide and atropine are effective as central analgesic, but not papaverine and benzyl mandelate.

5. 18 OBJECTIVE: To establish the method of assay for the bacterial endotoxin in papaverine hydrochloride and sodium chloride injection.

6. Papaverine alone (10 mg/kg) also reduced the acute death rate in anaphylatoxin shock and—to a lesser degree—in histamine shock.

7. P-286 is devoid of adrenolytic or sympatholytic actions, exerts a slight para-sympatholytic action and depresses heart rate and contractile force; it has a papaverine-like antispasmodic action.

8. Because of its unspecific-spasmolytic, papaverine-like properties prenylamine inhibited the actions of acetylcholine and histamine on the guinea pig ileum and the actions of acetylcholine and NA on the vas deferens of rat in a non-competitive manner.
