| adrenergic | (n) drug that has the effects of epinephrine, Syn. adrenergic drug |
| adrenergic | (adj) relating to epinephrine (its release or action), Syn. sympathomimetic |
| adrenergic agonist eyedrop | (n) a treatment for glaucoma; the eyedrops reduce intraocular pressure by decreasing the production of aqueous humor and increasing its drainage through the uveoscleral pathway |
| antiadrenergic | (adj) relating to blocking or reducing adrenergic effects in the body |
| alpha blocker | (n) any of various drugs that block alpha-adrenergic receptors; used in treating benign prostatic hyperplasia; relaxes the muscles of the prostate and bladder, Syn. alpha-adrenergic blocking agent, alpha-adrenergic blocker, alpha-blocker |
| alpha receptor | (n) receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasoconstriction and relaxation of intestinal muscles and contraction of smooth muscles), Syn. alpha-adrenergic receptor, alpha-adrenoceptor |
| beta blocker | (n) any of various drugs used in treating hypertension or arrhythmia; decreases force and rate of heart contractions by blocking beta-adrenergic receptors of the autonomic nervous system, Syn. beta-adrenergic blocking agent, beta-adrenergic blocker, beta-blocking agent |
| beta receptor | (n) receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasodilation and increased heart beat), Syn. beta-adrenoceptor, beta-adrenergic receptor |
