From these graphs two figures can be achieved, the '''ED50''' or '''EC50'''. The ED50 is the effective dose at which 50% of a maximal response occurs or 50% of individuals respond. The EC50 is the same but is the effective concentration. Agonists with higher affinities will have a lower concentration and so EC50 than an agonist with a lower affinity. The first drug is therfore said to be more '''potent'''.
