Cardio Pharma Flashcards
(110 cards)
formula for BP
CO x TPR
anti-htn drug class that decrease CO (the rest of the classes decrease TPR)
diuretics and beta blockers
which anti HTN drug class can decrease BOTH cardiac output and total peripheral resistance
diuretics
the only beta blocker that has a vasodilating property
carvedilol
True or false… methyldopa blocks peripheral sympathetic nerve endings
False. it blocks central sympathetic nerve endings
true or false… Valsartan blocks the AT2 receptors
false…it blocks AT1 receptors
anti-htn drugs that act on vasomotor center in the brain
methyldopa, clonidine
anti-a drugs that act on AT1 receptors
ARBs
anti-htn drugs that act on vascular smooth muscle
hydralazine, CCBs, nitroprusside
anti-htn drugs that act kidney tubules
thiazides
anti-htn drugs that is a renin inhibitor
aliskerin
central acting adrenergic blockers on what receptor
alpha 2
difference of methlydopa and clonidine in terms of specific site of action as alpha 2 agonists
methlydopa : CNS
clonidine: brainstem
anti-htn drug that blocks alpha 1
prazosin
which has more cardiac effect than vasodilating effect: dihydrophyrine or non dihydropyridine CCBs
non-dihydrophyrine has more cardiac effect (verapamil and diltiazem)
why is Verapamil better than Diltiazem in treating SVTs
because verapamil has greater action on the AV node. Dilitazem, on the other hand, has greater action on the SA node
which among verapamil, diltiazem, and amlodipine has the greatest vasodilating ability
amlodipine
which among verapamil, diltiazem, and amlodipine can cause more headache
amlodipine (bc it is a DHP CCB so it has vasodilating effect on blood vessels in the brain)
what anti-hypertensive drug class is contraindicated in patients with bilateral renal artery stenosis
ACEI/ARBS
true or false. ACEi/ARBS can cause hyperkalemia
True. by decreasing potassium excretion
which is better in patients with heart failure: ACEI or ARBS
ACEi because of added benefit of increasing bradykinin resulting to vasodilation resulting to decreased total peripheral resistance
anti-htn drug for patients with HPN and BPH
alpha 1 blockers (tamsulosins, prazosan)
which anti-htn drug classes can prevent ventricular remodelling
ACEi/ARBS and beta blockers, andspironolactone
beta blockers can be used for HF px class I- IV. True or false
False. can only be used in class I and II
