HYDROCHLOROTHIAZIDE vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, 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.
Oral: 25-100 mg daily in 1-2 divided doses. Maximum dose 200 mg/day.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

Terminal elimination half-life is 5.6–14.8 hours (mean ~9 hours). In patients with renal impairment (CrCl <30 mL/min), half-life is prolonged up to 24–48 hours, necessitating dose adjustment.
Clinical Note
moderateHydrochlorothiazide + Digoxin
"The risk or severity of adverse effects can be increased when Hydrochlorothiazide is combined with Digoxin."
Clinical Note
moderateHydrochlorothiazide + Digitoxin
"The risk or severity of adverse effects can be increased when Hydrochlorothiazide is combined with Digitoxin."
Clinical Note
moderateHydrochlorothiazide + Deslanoside
"The risk or severity of adverse effects can be increased when Hydrochlorothiazide is combined with Deslanoside."
Clinical Note
moderateTerminal elimination half-life is 8-12 hours in adults; prolonged to 20-30 hours in severe renal impairment (creatinine clearance <30 mL/min).
Primarily renal (≥95%) via glomerular filtration and tubular secretion, with approximately 60% of the dose excreted unchanged in urine. Minor biliary/fecal excretion accounts for <5%.
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
