Sympathomimetic drugs, also known as adrenergic agonists, are a class of medication that mimic the actions of the sympathetic nervous system. Some synonyms for sympathomimetic include adrenoceptor agonist, sympathomimetic amine, or adrenergic agonist. These medications are often prescribed to treat conditions such as asthma, nasal congestion, hypotension, and as an adjunct in the treatment of shock. Common sympathomimetics include epinephrine, norepinephrine, and albuterol. These drugs work by stimulating the adrenergic receptors in the body, which causes an increase in heart rate, blood pressure, and bronchodilation. Sympathomimetics can be powerful drugs and should only be taken as prescribed by a healthcare provider.
