HYDROCHLOROTHIAZIDE vs ORETIC
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.
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.
Oral: 25-100 mg daily in 1-2 divided doses. Maximum dose 200 mg/day.
25-100 mg orally once or twice daily; maximum 200 mg/day.

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: 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.
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: approximately 95% (primarily as unchanged drug via tubular secretion), Biliary/fecal: <5%
