Study Notes
Diuretics and Electrolyte Balance
- All diuretics can cause renal failure due to decreased effective circulating volume (ECV).
- All diuretics decrease potassium (K) levels, except for potassium-sparing diuretics, which increase potassium levels.
Diuretics and Acid-Base Balance
- All diuretics cause metabolic alkalosis, except for:
- Potassium-sparing diuretics, which decrease aldosterone, leading to increased H+ secretion.
- Carbonic anhydrase inhibitors (CA), which increase HCO3- excretion.
Diuretics and Calcium Balance
- Loop diuretics decrease calcium levels.
- Thiazide diuretics increase calcium levels.
