Hypertension Flashcards
hydrochlorothiazide
diuretic –> thiazide
@ distal convoluted tubule
moderate efficacy –> long-term outpatient
inhibit the co-transporter
hypokalemia
inhibit uric acid elimination = promote gout
chlorthalidone
diuretic –> thiazide
moderate efficacy (most effective thiazide)
inhibit the co-transporter
hypokalemia
inhibit uric acid elimination = promote gout
furosemide
loop diuretic high efficacy --> short-term, more severe cases inhibit Na/K/Cl transporter hypokalemia promote gout
ethacrynic acid
loop diuretic high efficacy --> short-term, more severe cases inhibit Na/K/Cl transporter hypokalemia promote gout
spironolactone
potassium sparing diuretic
low efficacy
antagonist at the Aldosterone receptor
reduces expression of Na/K ATPase
triamterine
potassium sparing diuretic
low efficacy
block the Na channel (apical membrane)
amiloride
potassium sparing diuretic
low efficacy
block the Na channel (apical membrane)
clonidine
indirect acting sympatholytic
alpha 2 agonist –>reduce sympathetic ns activity
reserpine
indirect acting sympatholytic release inhibitors (ACh) --> reduce sympathetic ns activity
propranolol
direct acting sympatholytic drug
beta blocker
non-seletive
atenolol
direct acting sympatholytic drug
beta blocker
cardioselective
**for diabetics and asthmatic patients
nadolol
direct acting sympatholytic drug
beta blocker
long-acting
prazosin
direct acting sympatholytic drug
alpha1 antagonist –> vasodilator
Gq coupled receptor
terazosin
direct acting sympatholytic drug
alpha1 antagonist –> vasodilator
Gq coupled receptor
hydralazine
oral drug
selective arterial dilator
Open K+ channels
minoxidil
oral drug
highly effective vasodilator
reserved for sever hypertension that does not respond to other drugs
Open K+ channels
diazoxide
parenteral highly effective and long-acting emergency situation (hypertension crises)
open K+ channels
sodium nitroprusside
parenteral
iv nitrate
emergency situation (hypertension crises)
Open K+ channels
verapamil

T1/2 = 2-4 hrs
extended release nifedipine
Non-cardioactive CCB
carvedilol
mixed beta blocker/vasodilator
Beta1, Beta2, and alpha1 antagonist
