Smooth muscle sensitization induced by vinblastine
- 11 Downloads
At the optimal concentration of 10 mg/l, vinblastine increases the submaximal contractions of the isolated guinea-pig ileum induced by the following agonists: acetylcholine, histamine, nicotine, angiotensine, prostaglandins E1 and F2α (but not serotonine). It also increases the contractions induced by transmural electrical stimulations of the guinea-pig ileum and reverses the inhibitory effect of non-steroidal anti-inflammatory drugs on these electrically-induced contractions.
