concentration of sodium nitroprusside at which the reduction in force during dilation of a blood vessel is half the maximum value (EC50) +
A calculated value for the concentration of sodium nitroprusside (SNP), the red-colored inorganic salt with the formula Na2[Fe(CN)5NO]-2H2O used as a potent vasodilator, at which the energy exerted during the active expansion in the diameter of a blood vessel in response to the application of SNP is halfway between the highest value, that is the force at greatest constriction (often measured in a pre-constricted blood vessel), and the lowest achievable value of such contractile energy during SNP-induced relaxation of the vessel wall (i.e. the maximum effect of SNP which is the minimum contractile energy).
