| sympathomimetic | 1. <physiology> The mimicking the effects of impulses conveyed by adrenergic postganglionic fibres of the sympathetic nervous system. 2. <pharmacology> An agent that produces effects similar to those of impulses conveyed by adrenergic postganglionic fibres of the sympathetic nervous system. Usually refers to drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Includes drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters. Synonym: adrenergic. Origin: Gr. Mimetikos = imitative (12 Dec 1998) |

| sympathomimetic amine | An agent that evokes responses similar to those produced by adrenergic nerve activity (e.g., epinephrine, ephedrine, isoproterenol). Synonym: adrenergic amine, adrenomimetic amine, sympathetic amine. (05 Mar 2000) |
| sympathomimetic amines | A broad class of chemicals which mimic the actions of activation of the sympathetic nervous system and have an amine (usually beta-phenyl-ethylamine) basic structure; examples include isoproterenol, amphetamine, ephedrine, and phenylephrine. (05 Mar 2000) |
| intrinsic sympathomimetic activity | The property of a drug that causes activation of adrenergic receptors so as to produce effects similar to stimulation of the sympathetic nervous system. (05 Mar 2000) |
