a1 blockers
|
Drugs that primarily cause arterial and venous dilation through their action on peripheral sympathetic neurons
|
|
antihypertensive drugs
|
Medications used to treat HTN.
|
|
CO - cardiac output
|
The amount of blood ejected from the left ventricle, measured in liters per minute
|
|
centrally acting adrenergic drugs
|
Drugs that modify the function of the SNS in the brain by stimulating a2 receptors, which has a reverse sympathetic effect that causes decreased BP.
|
|
essential HTN / primary HTN / idiopathic HTN
|
Elevated systemic arterial pressure for which no cause can be found and which is often the only significant clinical finding.
|
|
ganglionic blocking drugs
|
Drugs that prevent nerves from responding to the action of ACH by occupying the receptor sites for ACH (ie nicotinic receptors) on sympathetic and parasympathetic nerve endings.
|
|
HTN
|
A common, often asymptomatic disorder in which BP persistently exceeds 140/90 mm Hg.
|
|
nicotinic receptor
|
The receptor and site of action for ACH in both the parasympathetic and sympathetic nervous systems. Nicotinic receptors are located at the junction of the preganglionic and postgangliionic neurons of both of these systems.
|
|
orthostatic hypotension
|
A common adverse effect of adrenergic drugs involving a sudden drop in BP when a person change position, especially when rising from a seated or horizontal position.
|
|
prodrug
|
A drug that is inactive in its administered form and must be biotransformed in the liver to its active form.
|
|
secondary HTN
|
High BP associated with a primary disease such as renal, pulmonary endocrine, or vascular disease.
