How do sympathomimetic drugs work
WebParasympathomimetic Drugs. Drugs that activate muscarinic receptors in the peripheral nervous system are called parasympathomimetic drugs because they mimic the effects of acetylcholine on the parasympathetic nervous system. An example of a parasympathomimetic drug is pilocarpine, which is a nonspecific muscarinic agonist. WebFeb 8, 2015 · Drugs modify the activity of sympathetic neurons by increasing or decreasing the noradrenergic signal (see Fig. 11-1). Sympathomimetics may mimic noradrenergic transmission by acting directly on postsynaptic adrenergic receptors (e.g., phenylephrine), by facilitating NE release (e.g., amphetamine) or by blocking neuronal reuptake (e.g., cocaine).

WebSympathomimetics are drugs that mimic the stimulation of the sympathetic nervous system. They are classified as directly acting (act directly on α or β receptors), indirectly acting (act by providing more norepinephrine to act on α or β receptors), or mixed acting (act by both mechanisms).

It could be called your “automatic” nervous system, as it is responsible for many functions that you don’t have to think about to control. This can include control of your heart rate, blood pressure, digestion, urination and sweating, among other functions.
