WitrynaReceptors are responsible for selectivity of drug action. The molecular size, shape, and electrical charge of a drug determine whether—and with what affinity—it will bind to a … WitrynaBinding affinity is the concentration of a drug required to occupy 50% of the target molecules at equilibrium. This value quantifies the extent of target occupancy, which is used to predict in-vivo efficacy. 1; Residence time is a quantitative value representing the time a drug-receptor interaction takes to reach target occupancy.
