Additional inhibitory mechanisms on gastric secretion may be represented by pirenzepine-induced increase in somatostatin release from gastrointestinal system. Significant cytoprotective properties of pirenzepinehave been observed on a variety of experimentally induced peptic ulcerations. Pirenzepine (5-500 μg\/mL) inhibits agonist-(acetylcholine-, carbachol- or nicotine-) induced contractions of the toad isolated rectus abdominis muscle, and depresses electrically provoked twitches of the rat phrenic nerve-hemidiaphragm muscle preparation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn Vivo:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003ePirenzepine is potent in impairing learning of an avoidance; much higher doses are required to antagonize other central muscarinic effects. Pirenzepine is found to impair passive avoidance learning when given i.c.v. 20 min pre-training. The median latencies in pirenzepine-treated animals are 79.5, 11, 27 and 25.5 seconds with doses of 0.03, 0.1, 0.3 and 1 μg per mouse respectively. Acid and pepsin secretion stimulated by either bethanechol or the vagus are inhibited in a dose-responsive manner by pirenzepine. Pirenzepine (5-25 mg\/kg i.v.) depresses indirect electrical stimulation-evoked twitches of the cat tibialis anterior and soleus muscle preparations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProducts are for research use only.
