CHLOROTHIAZIDE vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorothiazide inhibits the Na+-Cl- symporter in the distal convoluted tubule, reducing sodium and chloride reabsorption and promoting diuresis. It also causes vasodilation by reducing peripheral vascular resistance.
Trichlorex is a thiazide-like diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and increasing water excretion.
500 mg to 1000 mg orally or intravenously once or twice daily.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.
