Clinical experience with an oral diuretic, trichlormethiazide

Area of Science:

• Pharmacology
• Nephrology
• Cardiology

Background:

• Diuretic therapy is essential for managing conditions like hypertension and edema.
• Understanding the long-term effects of diuretics on renal and systemic markers is crucial for patient safety and treatment efficacy.

Purpose of the Study:

• To evaluate the long-term impact of trichlormethiazide on urine and blood parameters.
• To assess the safety and efficacy of trichlormethiazide in patients with essential hypertension or edema.

Main Methods:

• Fourteen patients with essential hypertension or edema received trichlormethiazide therapy.
• Treatment duration ranged from one to 12 months (mean 5.4 months).
• Long-term effects on urine values, blood counts, serum electrolytes, blood urea nitrogen, serum uric acid, and blood pressure were monitored.

Main Results:

• No significant changes were observed in urine values, blood counts, or serum sodium and potassium levels.
• Two patients with renal failure experienced nitrogen retention; others showed no significant blood urea nitrogen changes.
• Serum uric acid levels decreased post-treatment, and blood pressure lowered in nine patients.
• No toxic effects were reported during the study period.

Conclusions:

• Long-term trichlormethiazide administration appears safe, with no significant adverse effects on urine or blood parameters in most patients.
• The drug demonstrated a potential benefit in lowering blood pressure and serum uric acid levels.
• Caution is advised for patients with renal failure due to potential nitrogen retention.
