Effects of Midazolam on Intracellular Calcium sup 2+ and Tension in Airway Smooth Muscles

Abstract
Background It has been demonstrated that a group of minor tranquilizers, benzodiazepines, are able to relax airway smooth muscles. To determine the underlying mechanisms of this phenomenon, the effects of midazolam on the intracellular Calcium2+ concentration ([Calcium2+]i) and tension in airway smooth muscles were investigated.
