Sympathomimetic Drug

Sympathomimetic drugs are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. The action of sympathomimetic drugs can be classified as direct and indirect action. The direct mode of activating adrenergic receptors involve the mimicking of endogenous molecules through agonist molecules, and the indirect mode of action involve mechanisms of increasing the release, or decreasing the breakdown and removal of noradrenaline.
