Even measured this fashion, a dose-response curve can only provide a single legitimate objective: it displays the average romantic relationship in between the dose plus the initial
Potency (power) refers back to the level of drug (usually expressed in milligrams) essential to produce an outcome, for example relief of suffering or reduction of blood pressure.
