Study Notes
Diuretics and Their Side Effects
- Hypokalemia (potassium depletion) is a common side effect of diuretics.
- Hypercalcemia (elevated calcium levels) is not a common side effect of diuretics.
Diuretics and Ototoxicity
- Ethacrynic acid is a diuretic known to have the highest risk of causing ototoxicity (hearing loss or damage).
Mechanism of Action of Thiazide Diuretics
- Thiazide diuretics inhibit sodium reabsorption in the early distal tubule of the nephron, leading to increased sodium and water excretion in the urine.
- This results in decreased blood volume, cardiac output, and blood pressure.
