Refers to a substance that produces a physiological effect similar to that produced by stimulation of the sympathetic nervous system.
A substance that produces a reduction or relief of nasal congestion.
Referring to a drug such as dopamine hydrochloride which stimulates the activity of the sympathetic nervous system and is used in cardiac shock following myocardial infarction and in cardiac surgery.
Drugs that facihtate or increase activity within the sympathetic nervous system.
Having an effect (as from a drug) similar to that caused by stimulation of the sympathetic nervous system (e.g., dilating the bronchi).
A drug that has the effect of stimulating the sympathetic nervous system. The actions of sympathomimetic drugs are adrenergic (resembling those of norepinephrine). Alpha-adrenergic drugs, e.g. phenylephrine, constrict blood vessels in the skin and intestine and are used in nasal decongestants; beta-adrenergic drugs, e.g. salbutamol, relax bronchial smooth muscle and are used as bronchodilators. Ephedrine and isoprenaline are less selective and have both alpha- and betaadrenergic effects; if used as bronchodilators, these drugs may have unwanted side-effects on the heart.

Adrenergic; producing effects resembling those resulting from stimulation of the sympathetic nervous system, such as effects following the injection of epinephrine.
Referring to a medication that replicates the effects of organ and structure stimulation by the sympathetic nervous system. The sympathetic nervous system originates in the thoracic and lumbar regions of the spinal cord and typically counteracts or inhibits the physiological effects of another division of the nervous system. This includes reducing digestive secretions, accelerating heart rate, and constricting blood vessels.
Mimicking the function of the sympathetic nervous system.
A substance that creates effects resembling those of signals transmitted by adrenergic postganglionic fibers in the sympathetic nervous system.
