Hypertension (Effects of Drugs)

decrease heart rate, dilate blood vessel

beta-blockers and cardioselective beta-blocker drugs reduce high blood pressure (hypertension) by doing what?

beta blocker

a drug group that blocks the action of epinephrine at ALL beta receptors

cardioselective beta-blocker

a drug group that blocks the action of epinephrine at beta-1 receptors in the heart, beta-2 receptors in the blood vessels and do not block action of beta-2 receptors in the bronchi

beta-blockers, cardioselective beta-blocker

list the (generic) names of two drug groups that decrease heart rate and dilate blood vessel

alpha/beta blocker

a drug group that at the smooth blood vessel block both alpha receptors and beta-1/beta-2 receptors

alpha blocker

a drug group that block alpha-1 receptors (causing both arteries and veins to dilate)

calcium channel blockers

a drug group that block the movement of calcium into heart and smooth muscles (therefore restricting muscle contraction)

ACE inhibitor

a drug group that prevents angiotensin I from converting into angiotenin II; angiotensin II is a strong vasoconstrictor that raises blood pressure

angiotensin II receptor blocker

a drug group that prevents angiotensin II from acting (angiotensin II is a strong vasoconstrictor that raises blood pressure)

renin inhibitor

a drug group that blocks that production of renin in the kidneys; less renin = less angiotensin I

peripheral vasodilators

a drug group that causes the smooth muscle in the blood vessels to dilate

aldosterone receptor inhibitor

a drug group that blocks corticosteroid hormone that is secreted by the cortex of the adrenal gland; this hormone increase reabsorption of sodium; the reabsorption process of sodium bring water with it thereby increasing BP.

Alpha-2 blockers

a drug group that stimulates alpha-2 receptors in the vasomotor center of the brain; to decrease the number of nerve impulses; resulting in the adrenal medulla producing less epinephrine

hypercholesterolemia

An excessive amount of cholesterol in the blood
