Cholinomimetics. • Cholinomimetics: explain how (a) directly acting and (b) indirectly acting cholinomimetic drugs produce their biological actions and state why the former are more selective in their actions. Graded Dose-response Relationships. Agonist . drugs mimic the action of the original endogenous ligand for the receptor (for example, isoproterenol mimics norepinephrine on β1 . receptors . of the heart). The magnitude of the drug effect depends on the drug concentration at the receptor site, which, in turn, is determined by both the dose of drug administered and by the drug’s pharmacokinetic profile, such as rate of absorption, distribution, metabolism, and elimination.
