HYDROFLUMETHIAZIDE vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydroflumethiazide 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 promoting diuresis. It also causes vasodilation by reducing peripheral vascular resistance.
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: 25-50 mg once daily; may increase to 100 mg/day in divided doses if needed.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

Clinical Note
moderateHydroflumethiazide + Digoxin
"The risk or severity of adverse effects can be increased when Hydroflumethiazide is combined with Digoxin."
Clinical Note
moderateHydroflumethiazide + Digitoxin
"The risk or severity of adverse effects can be increased when Hydroflumethiazide is combined with Digitoxin."
Clinical Note
moderateHydroflumethiazide + Deslanoside
"The risk or severity of adverse effects can be increased when Hydroflumethiazide is combined with Deslanoside."
Clinical Note
moderateTerminal elimination half-life of 6-9 hours in patients with normal renal function; clinically, this supports once-daily dosing in hypertension but may require twice-daily dosing in some patients with impaired renal function
Terminal 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 (approximately 85% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%)
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
