WebA drug’s ability to affect a given receptor is related to the drug’s affinity (probability of the drug occupying a receptor at any given instant) and intrinsic efficacy (intrinsic activity—degree to which a ligand activates receptors and leads to cellular response). A drug’s affinity and activity are determined by its chemical structure. WebDose-Response Relationships. Regardless of how a drug effect occurs—through binding or chemical interaction—the concentration of the drug at the site of action controls the effect. However, response to concentration may be complex and is often nonlinear. The relationship between the drug dose, regardless of route used, and the drug ... cent symbols on iphone WebThe dose–response relationship is the measurement of the relationship between the dose of a substance administered and its overall effect (the response), either therapeutic or toxic. The dose–response relationship is based on observed data from experimental animal, human clinical, or cell studies.
