The direct effect of protamine sulfate upon myocardial inotropism was studied using an isolated canine heart muscle preparation. Isometric force (F) was decreased to 87.6 +/- 1.2% of control values by a concentration of 50 x 10(-3) g/L protamine, which is approximately equal to the estimated serum concentration of protamine when administered clinically in doses of 4 mg/kg. The decrease in F was accompanied by a decrease in the maximum velocity of force development (dF/dt) but no alteration in time to peak force. Administration of the preservative of protamine sulfate did not alter F and dF/dt. This suggests that protamine produces a direct negative inotropic effect, mediated by a decrease in intensity but not by a decrease in duration of the active state.
