    Study Notes

    Thiazide Diuretics

    • Increase excretion of halides and H+, while reducing Ca2+ excretion and enhancing reabsorption.
    • Moderate efficacy, maximum Na+ excretion limited to 5-7% of filtered load.
    • Ineffective with GFR < 30-40 ml/min, potentially harmful in renal failure.
    • Dependent on renal prostaglandins (PGs), less so compared to loop diuretics.

    Therapeutic Uses of Thiazides

    • Indicated for mild edematous states (cardiac, hepatic, renal).
    • Effective in treating essential hypertension; often combined with other antihypertensives.
    • Used to decrease urinary Ca2+ excretion in hypercalciuria and renal Ca2+ stone management.
    • Can reduce urine volume in nephrogenic diabetes insipidus (DI), demonstrating a “paradoxical antidiuretic action” possibly linked to ADH receptor sensitivity improvement.

    Adverse Effects of Thiazides

    • Risk of hypovolemia and hypotension.
    • Electrolyte disturbances: hyponatremia, hypokalemia, and hypokalemic metabolic alkalosis.
    • Hyperuricemia similar to loop diuretics; potential for hyperglycemia due to decreased insulin release and glucose utilization.
    • May cause hyperlipidemia (increased cholesterol and LDL by 5-15%).
    • Allergic reactions possible due to sulfonamide derivatives (skin rash, dermatitis, rare thrombocytopenia).

    Potassium-Sparing Diuretics
