Loopdiureticsare the most potent diuretics that reduce ECF, cardiac output, and blood pressure. The mechanism of action forloop diureticslikefurosemideis by inhibiting the apical sodium/potassium/chloride transporter in the thick ascending limb of the loop of Henle. Unlike thiazide diuretics, loop diu...
Furthermore, these agents can cause hyperkalemia especially when combined with ACE inhibitors or potassium-sparing diuretics. Small-dose infusions of dopamine (<2.5 μg per kilogram per minute) have been used in patients with heart failure, since dopamine may improve renal hemodynamics and the ...
which are most commonly used in CHF Adverse effects Hemodynamics–eg, reflex tachcardia, SNS activation with catecholamine release, activation of RAA system, renal function–eg, ↓ perfusion leading to ↑ BUN and creatinine, electrolytes–eg, ↓ potassium and/or magnesium. SeePotassium-sparing diure...
What is mannitol, and what is it used for? Mannitol is a diuretic medication that promotes urination and is administered intravenously to reduce intracranial pressure and intraocularpressurefrom fluid buildup. Mannitol is used to treat acutekidney failurein the phase of reduced urine output (oliguric...
The least potent diuretic drug: a) Osmotic diuretics b) Loop diuretics c) Thiazide diuretics d) Potassium-sparing diuretics Besides beta-blockers and the angiotensin system, what is the mechanism used to treat high blood pressure that involves water? Or what does the medication do to your body...

The potassium-sparing diuretics include two drug classes, namely, epithelial sodium channel (ENaC) blockers and mineralocorticoid receptor antagonists (MRAs). 5.1. The Potassium-Sparing Diuretics ENaC is the primary channel for sodium reabsorption in the principal cells of the connecting tubules and col...
