What are Sympathomimetics?
Sympathomimetics are drugs that mimic the effects of the sympathetic nervous system by activating adrenergic receptors. They are used primarily in respiratory, cardiovascular, and local vasoconstriction therapies. Major subclasses include alpha-adrenergic agonists, beta-adrenergic agonists, and mixed agents.
