Week 4: Cardiovascular-Renal Drugs: Diuretics and Arrhythmias Flashcards
what has been known for many years to decrease blood pressure in hypertensive patients.
dietary sodium restriction
sodium is believed to contribute to vascular resistance by increasing vessel stiffness and neural reactivity, possibly r/t altered ________ with a resultant increase in intracellular ______.
sodium-calcium exchange
calcium
_____ diuretics are appropriate for most patients with mild or moderate HTN and normal renal and cardiac fuction
thiazide diuretics
diuretics acting on ______ such as furosemide, bumetanide, and torsemide are necessary for severe hypertension when multiple drugs with sodium-retaining properties are used (renal insufficiency, cardiac failure, or cirrhosis - in which sodium retention is large)
loop of Henle
______ _____ _____ have a favorable effect on cardiac function in people with heart failure
aldosterone receptor antagonist
in the treatment of hypertension, the most common adverse effect of diuretics is _____
potassium depletion (hypokalemia)
potassium loss is coupled to the reabsorption of sodium, and restriction of dietary sodium intake, _______ potassium loss
minimizes
diuretics increase uric acid concentrations and may precipitate ____
gout
Potassium-sparing diuretics may produce ______ particulary in those with renal insufficiency and those taking ACE inhibitors or ARBs
hyperkalemia
Spironolactone is associated with _____ in men.
gynecomastia
diuretics with major action in the Proximal convoluted tubule (PCT)
carbonic anhydrase inhibitors
adenosine antagonist
diuretics with major action in the Thick Ascending Limb of Henle Loop
loop diuretics
diuretics with major action in the Distal Convoluted tubule (DCT)
thiazides
Diuretics with major action in the Cortical collecting tubule (CCT)
K+-sparing diuretics
adenosine antagonists
Diuretics with major action in the medullary collecting duct
vasopressin antagonist
