Q

Bumex/Bumetanide, Lasix/Furosemide, Demadex/Torsemide

LOOP DIURETICS

A

Antihypertensive action-renal vasodilation: provides increase GFR and decrease in peripheral vascular resistance
More potent than thiazide diuretics-cause rapid diuresis resulting in decreased vascular fluid volume, decreased cardiac output, and decreased BP
Need to be taken early to avoid nocturia
IV doses need to be given SLOWLY to avoid hypotension and ototoxicity (hearing loss)
