B4-102 CBCL: Hypertension and Treatment Flashcards
(113 cards)
inhibit NaCl reabsorption in distal convoluted tubule
thiazides
preferred antihypertensive drugs in elderly
- thiazides
- Ca+ channel blockers
preferred thiazide due to long half life and proven reduction of CVD
chlorthalidone
uses for thiazides
* hypertension
* congestive heart failure
* nephrolithiasis
* nephrogenic diabetes insipidus
adverse effects: thiazides
- hypokalemic metabolic acidosis
hyponatremia - hypergluc
glycemia
lipidemia
uricemia
calcemia
potassium sparing diurectics
Keep your SEAT
Spironolactone
Eplerenone
Amiloride
Triamterene
used to counteract hypokalemia caused by loop or thiazide diuretics
potassium sparing diuretics
end in -pril
ACE inhibitors
how do ACE inhibitors lower bp?
reduced angiotensin and increased bradykinin cause vasodilation
adverse effects: ACE inhibitors
Captopril’s CATCHH
cough
angioedema
teratogen
creatinine (increased)
hyperkalemia
hypotension
first choice of treatment for hypertensive patients with
* diabetes
* chronic renal disease
* left ventricular hypertrophy
ACE inhibitors
lower BP without compromising blood supply to heart, brain, or kidneys
ACE inhibitors
do not use in combination with ARBs or direct renin inhibitor
ACE inhibitor
end in -sartan
angiotensin receptor antagonists
how do angiotensin receptor antagonists differ from ACE inhibitors?
- more specific- no bradykinin increase
- more complete inhibition
adverse effects: ARBs
- hyperkalemia
- decreased GFR
- hypotension
- teratogen
similar to ACE, without coughing/bradykinin induced effects
reduced intracellular Ca+ causing arteriolar smooth muscle relaxation
Ca+ channel blockers
do not cause reflex tachycardia
verapamil and diltiazem
verapamil
diltiazem
-dipines
Ca+ Channel blockers
- strongest vasodilators
- most likely to produce reflex tachycardia
dihyropyridines
-dipines
adverse effects: dihydropyridines
peripheral edema
flushing
dizziness
adverse effects: nondihydropyridines
verapamil and dilitiazem
- cardiac depression
- bradycardia
- AV block
- constipation
- orally active
- dose-dependent reduction of plasma renin
- dose dependent reduction of blood pressure
aliskiren
contraindications: aliskiren
- pregnancy
- do no combine with ACE inhibitors or ARB
