| adrenergic agonists | Drugs that bind to and activate adrenergic receptors. (12 Dec 1998) |
|---|---|
| adrenergic alpha-agonists | Drugs that selectively bind to and activate alpha adrenergic receptors. (12 Dec 1998) |
| adrenergic beta-agonists | Drugs that selectively bind to and activate beta-adrenergic receptors. (12 Dec 1998) |
| gaba agonists | Drugs that bind to and activate gaba receptors (receptors, gaba). (12 Dec 1998) |
| cholinergic agonists | Drugs that bind to and activate cholinergic receptors. (12 Dec 1998) |
| myeloablative agonists | Agents that destroy bone marrow activity. They are used to prepare patients for bone marrow or stem cell transplantation. (12 Dec 1998) |
| serotonin agonists | Agents that have an affinity for serotonin receptors and are able to mimic the effects of serotonin by stimulating the physiologic activity at the cell receptors. These compounds are used as antidepressants, anxiolytics, and in the treatment of migraine. (12 Dec 1998) |
| nicotinic agonists | Drugs that bind to and activate nicotinic cholinergic receptors (receptors, nicotinic). Nicotinic agonists act at postganglionic nicotinic receptors, at neuroeffector junctions in the peripheral nervous system, and at nicotinic receptors in the central nervous system. Agents that function as neuromuscular depolarising blocking agents are included here because they activate nicotinic receptors, although they are used clinically to block nicotinic transmission. (12 Dec 1998) |
| dopamine agonists | Drugs that bind to and activate dopamine receptors. (12 Dec 1998) |
| excitatory amino acid agonists | Drugs that bind to and activate excitatory amino acid receptors. (12 Dec 1998) |
| lhrh agonists | Compounds that are similar to LHRH (luteinizing hormone-releasing hormone). (12 Dec 1998) |
| augmented histamine test | A test for maximal production of gastric acidity or anacidity; after preliminary administration of an antihistamine, histamine acid phosphate is injected subcutaneously in a dose of 0.04 mg/kg of body weight, followed by analysis of gastric contents. Synonym: augmented histamine test. (05 Mar 2000) |
| receptors, histamine | Cell-surface proteins that bind histamine and trigger intracellular changes influencing the behaviour of cells. Histamine receptors are widespread in the central nervous system and in peripheral tissues. Three types have been recognised and designated h1, h2, and h3. They differ in pharmacology, distribution, and mode of action. (12 Dec 1998) |
| receptors, histamine h1 | A class of histamine receptors discriminated by their pharmacology and mode of action. most histamine h1 receptors operate through the inositol phosphate/diacylglycerol second messenger system. Among the many responses mediated by these receptors are smooth muscle contraction, increased vascular permeability, hormone release, and cerebral glyconeogenesis. (12 Dec 1998) |
| receptors, histamine h2 | A class of histamine receptors discriminated by their pharmacology and mode of action. Histamine h2 receptors act via g-proteins to stimulate adenylate cylase. Among the many responses mediated by these receptors are gastric acid secretion, smooth muscle relaxation, inotropic and chronotropic effects on heart muscle, and inhibition of lymphocyte function.
