Relaxant effects of sulfonylureas on induced contractions of rat uterine smooth muscle: role of intracellular calcium.


We have investigated the action of tolbutamide and glibenclamide in a Ca-dependent process: the contractile activity of smooth muscle (uterus). The results obtained show that sulfonylureas are capable of relaxing contractions of rat uterus induced by various agents: oxytocin, acetylcholine and KCl in a medium with Ca2+. The capacity of sulfonylureas to also… (More)
