ORETIC vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrochlorothiazide inhibits the sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride, leading to increased excretion of water and electrolytes.
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.
25-100 mg orally once or twice daily; maximum 200 mg/day.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

Terminal elimination half-life: 6-15 hours (average 10 hours); prolonged in renal impairment and heart failure; clinical context: duration of diuretic effect correlates with half-life, requiring once or twice daily dosing.
Terminal elimination half-life is 8-12 hours in adults; prolonged to 20-30 hours in severe renal impairment (creatinine clearance <30 mL/min).
Renal: approximately 95% (primarily as unchanged drug via tubular secretion), Biliary/fecal: <5%
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
