Effects of tiemonium iodide (tiemonium, 20 micrograms/kg), mepenzolate bromide (mepenzolate, 20 micrograms/kg), butylscopolamine bromide (butylscopolamine, 50 micrograms/kg) and atropine sulfate (atropine, 10 micrograms/kg) on the colonic motility in dogs were evaluated using a balloon method. The frequency of the wave

The possible interaction between the muscarinic receptor and the antiarrythmic drug amiodarone was studied physiologically in the guinea pig ileum, as well as by competition binding experiments in rat brain and cardiac tissues, using the highly specific tritiated muscarinic antagonist
Research communications in chemical pathology and pharmacology, 36(3), 503-506 (1982-06-01)
The mydriatic effects of mepenzolate, a quarternary antimuscarinic agent, has been investigated and compared with those of atropine by pupillographic analysis in rabbits. The time-response curve for the onset of action for the agents (half-time, ca.5 min) was the same

Seventy adults in the United States with acute diarrhea who were attending classes in Guadalajara, Mexico, enrolled in a double-blind placebo-controlled treatment study of an anticholinergic drug, mepenzolate bromide (MZB). Thirty-five patients received MZB (50 mg) and 35 received placebo
Lowering temperature from 37 degrees C to 22, 18, and 14 degrees C triggered automaticity of smooth longitudinal muscle of guinea pig isolated ileum. The amplitude of the hypothermia-induced automaticity was dependent on the degree of temperature drop: the greater
