40
Q

Acetazolamide

A

CA inhibitor, also blocks HCO3- Reabsorption
Used for Glaucoma, Metabolic Alkalosis, altitude
AE: Metabolic acidosis, Ammonium, Sulfa allergy

41
Q

Mannitol

A

Osmotic diuretic, increases tubular fluid osmolarity
Used for shock, ODs, ICP (when the bleed stops)

42
Q

Loop drugs

A

Furosemide and Ethacrynic acid

43
Q

Furosemide
