These receptors actually reduce sympathetic outflow Secondly they affect the kidneys reducing the activity of renin. A drug with neuroprotective activity should increase the resistance of retinal ganglion cells (RGC) to chronic stress or injury and therefore enhance survival.

Brief review of drugs affecting -adrenergic receptors (18) agonists of alpha adrenergic receptors. pharmacology of alpha-agonist drugs.Alpha-adrenoceptor agonists (-agonists) bind to -receptors on vascular smooth muscle and induce smooth contraction and vasoconstriction, thus mimicking the effects of sympathetic adrenergic nerve activation to the blood vessels. An adrenergic agent is a drug, or other substance, which has effects similar to, or the same as, epinephrine (adrenaline). Thus, it is a kind of sympathomimetic agent. Alternatively, it may refer to something which is susceptible to epinephrine, or similar substances, such as a biological receptor Adrenergic alpha-Receptor Blockaders Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. ALPHA2 AGONISTS AS SYMPATHOLYTICS Clonidine. Actions and Therapeutic Uses 1. This drug stimulates alpha2 receptors in the nucleus tractus solitarius (NTS) to decrease sympathetic outflow to the heart and blood1. These drugs are competitive antagonists of the beta adrenergic receptors. The alpha-adrenergic receptor carries a negatively charged group (phosphate).
