sympathomimetic

[sim′pəthō′mimet′ik]
Etymology: Gk, sympathein + mimesis, imitation
a pharmacological agent that mimics the effects of stimulation of organs and structures by the sympathetic nervous system. It functions by occupying adrenergic receptor sites and acting as an agonist or by increasing the release of the neurotransmitter norepinephrine at postganglionic nerve endings. Various sympathomimetic agents are used as decongestants of nasal and ocular mucosa, such as bronchodilators in the treatment of asthma and vasopressors and cardiac stimulants in the treatment of acute hypotension and shock; they are also used for maintaining normal blood pressure during operations using spinal anesthesia. Drugs in this group include cyclopentamine, DOBUTamine, DOPamine, epHEDrine, isoproterenol, metaproterenol, metaraminol, mephentermine, methoxamine, methoxyphenamine, naphazoline, norepinephrine, phenylephrine, propylhexedrine, protokylol, pseudoephedrine, terbutaline sulfate, tetrahydrozoline, tuaminoheptane, xylometazoline, and epINEPHrine, a synthetic isomer of the hormone secreted by the adrenal medulla. Adverse effects of sympathomimetic drugs may be nervousness, severe headache, anxiety, vertigo, nausea, vomiting, dilated pupils, glycosuria, and dysuria. Also called adrenergic drug.

Synonym(s): sympathicomimetic.

sympathomimetic

Of any agent that simulates or stimulates the sympathetic nervous system. ADRENERGIC. Sympathomimetic action can increase the heart output by 100 per cent over resting values. It can constrict arteries and increase the blood pressure. And it can widen the air tubes of the lungs allowing more free access of large volumes of air.

Sympathomimetic

Denoting a drug that mimics the effects of stimulation of organs and structures by the sympathetic nervous system. The sympathetic nervous system pertains to the part of the nervous system originating in the thoracic and lumbar regions of the spinal cord. In general, it inhibits or opposes the physiological effects of another aspect of the nervous system, as in tending to reduce digestive secretions, speed up the heart, and contract the blood vessels.
