Aldactone (Spironalactone) is a Potassium sparing diuretic. Keeps you from pissing out so much Potassium.
Diamox (Acetazolamide) Carbonic Anhydrase inhibitor diuretic, makes you piss.
Lasix (Furosemide) Loop diuretic. Makes you piss alot. You lose Potassium.
Many times prescribe Aldactone in addition to Lasix to prevent Hypokalemia (low Potassium level in blood) Or use Potassium supplement.
Diamox helps by essentially stimulating breathing. This is a simple answer to a complex explanation involving partial pressures of O2, metabolic acidosis, the Loop of Henle, respiratory drive, central chemoreceptors, the carotid body, etc ad nauseum.
