Drugs that inhibit the function of both central (brain) and peripheral sympathetic postganglionic neurons by depleting their stores of norepinephrine and serotonin, resulting in a hypotensive effect. Reserpine is the only currently available drug in this class in the United States.
adrenergic neuronal blocker
Drugs that primarily cause arterial and venous dilation through action on peripheral sympathetic neurons.
Medications used to treat hypertention.
antihypertensive agents
Amount of blood ejected from the left ventricle, measured in liters per minute.
cardiac output
Drugs that modify the function of the sympathetic nervous system in the brain by stimulating alpha2-receptors, which has a reverse sympathetic effect, causing decreased blood pressure.
centrally acting adrenergic agents
An elevated systemic arterial pressure for which no cause can be found and that is often the only significant clinical finding.
essential hypertension (also called primary or idiopathic hypertension)
Agents that prevent nerves from responding to the action of acetylcholine by occupying the receptor sites for acetylcholine (i.e., nicotinic receptors) on sympathetic and parasympathetic nerve endings.
ganglionic-blocking agents
A common, often asymptomatic disorder in which blood pressure persistently exceeds 140/90 mm Hg.
The receptor and site for action for acetylcholine in both the parasympathetic and sympathetic nervous systems. They are located at the junction of the pre- and postganglionic neurins of both of these systems.
nicotinic receptor
A common side effect of adrenergic drugs involving a sudden drop in blood pressure when patients change position, especially when rising from a seated or horizontal position.
orthostatic hypotension
A drug that is inactive in its present form and must be biotransformed in the liver to its active form.
Any one of more than 20 alkaloids derived from the root of a climbing shrub; used in the treatment of hypertension in the form of the drug reserpine.
Rauwolfia alkaloid (from the plant Rauwolfia serpentina)
High blood pressure associated with several primary diseases, such as renal, pulmonary, endocrine, and vascular diseases.
secondary hypertension
