Agonists and Antagonists. An agonist is a drug that binds to receptors and thereby alters (stabilizes) the proportion of receptors that are in the active conformation, resulting in a biologic response. A full agonist results in a maximal response by occupying all or a fraction of receptors.t considers both drug action, which refers to the initial consequence of a drug-receptor interaction, and drug effect, which refers to the subsequent effects. The drug action of digoxin, for example, is inhibition of membrane Na + /K + -ATPase; the drug effect is augmentation of cardiac contractility.
General Pharmacology. Beta-adrenoceptor agonists (Î²-agonists) bind to Î²-receptors on cardiac and smooth muscle tissues. They also have important actions in other tissues, especially bronchial smooth muscle (relaxation), the liver (stimulate glycogenolysis) and kidneys (stimulate renin release).herefore, Î²-agonists mimic the actions of sympathetic adrenergic stimulation acting through Î²-adrenoceptors. Overall, the effect of Î²-agonists is cardiac stimulation (increased heart rate, contractility, conduction velocity, relaxation) and systemic vasodilation.
