6 for the same receptor). Potency describes the relationship between the drug dose and the magnitude of the effect (1-5).High potency induces a strong effect with a low drug dose. Efficacy is the invivo potency; the maximum response achieved from a drug (1-3,5).The interaction (e.g. absorption, metabolism, excretion) of the drug in the body may alter theto Figure 1. Synergy of potency and efficacy (α and β) correspond to orthogonal geometric transformations of the dose-response surface and are therefore analogous to the geometric translations of the single-drug dose-response curve described by classic pharmacology parameters quantifying a drug’s potency and efficacy (EC50 and Emax).An active ingredient is repeatedly diluted by factors of 10 ("X") or 100 ("C") and shaken ("succussed").
