HYGROTON vs ZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium reabsorption in the distal convoluted tubule by binding to the thiazide-sensitive sodium-chloride cotransporter (NCC), leading to increased excretion of sodium, chloride, and water.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride and increasing excretion of water, sodium, chloride, potassium, and bicarbonate.
25-50 mg orally once daily; may increase to 100 mg once daily for resistant hypertension or edema. Maximum dose 100 mg/day.
10 mg orally once daily.

Terminal elimination half-life is approximately 40-50 hours, extending up to 70 hours in patients with renal impairment, allowing for once-daily dosing.
Clinical Note
moderateBendroflumethiazide + Digoxin
"The risk or severity of adverse effects can be increased when Bendroflumethiazide is combined with Digoxin."
Clinical Note
moderateMethyclothiazide + Digoxin
"The risk or severity of adverse effects can be increased when Methyclothiazide is combined with Digoxin."
Clinical Note
moderateHydrochlorothiazide + Digoxin
"The risk or severity of adverse effects can be increased when Hydrochlorothiazide is combined with Digoxin."
Clinical Note
moderate6-8 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (eGFR <30 mL/min).
Renal (approximately 50-60% as unchanged drug and metabolites); biliary/fecal elimination accounts for a minor fraction, less than 10%.
Renal: 70% unchanged; Biliary/fecal: 30% (as metabolites and parent compound).
