Cerebral vasoconstriction is associated with increased cytosolic Ca2+ concentration in vascular smooth muscle, presumably due to Ca2+ influx and Ca2+ release from intracellular stores. We tested the hypothesis that dantrolene (a blocker of Ca2+-induced Ca2+ release from the ryanodine receptor channel on the sarco-endoplasmic reticulum) would potentiate the action of nimodipine (a voltage-dependent L-type Ca2+ channel blocker, considered standard therapy for SAH) in inhibiting the vasoconstriction of isolated cerebral arteries.
