Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Metahydrin (trichlormethiazide) is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and increasing excretion of water, sodium, chloride, and potassium.
Bendroflumethiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, reducing sodium and chloride reabsorption and promoting diuresis.
Oral, 50-100 mg once daily. Maximum 200 mg/day.
Hypertension: 2.5 mg orally once daily; may increase to 5 mg daily if needed. Edema: 2.5 to 10 mg orally once daily.

18-30 hours (clinically relevant for once-daily dosing in hypertension; prolonged in renal impairment)
Terminal elimination half-life: 6-9 hours; prolonged in renal impairment and in elderly patients.
Renal: 30% (fecal: 70% as unabsorbed drug, primarily biliary elimination; <1% unchanged in urine)
Renal excretion: approximately 95% as unchanged drug; biliary/fecal: <5%.
