Sulfinpyrazone exerts significant electrophysiologic actions under various experimental conditions. It raises the ventricular fibrillation threshold as well as the mid diastolic threshold and prolongs the effective refractory period. In the acutely ischemic heart, it attenuates the effect of coronary occlusion on the ventricular fibrillation threshold but has no effect after reperfusion. A protective influence of the drug is also evident during sympathetic humoral stimulation with norepinephrine. The antifibrillatory effect of sulfinpyrazone is additive to the changes elicited by beta adrenergic blockade with practolol or cardiac membrane stabilization with lidocaine.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
