Causes skeletal muscle relaxation through a direct effect on skeletal muscle, probably by interfering with release of calcium from the sarcoplasmic reticulum.108 109
Interference with calcium release from the sarcoplasmic reticulum may prevent the increase in myoplasmic calcium that activates acute catabolism of skeletal muscle cells in patients with anesthesia-induced malignant hyperthermia.108
Has little or no effect on the contraction of cardiac or intestinal smooth muscle, except possibly at concentrations higher than those required for effects on skeletal muscle contraction.a
