CHLOROTHIAZIDE vs HYDROFLUMETHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorothiazide inhibits the Na+-Cl- symporter in the distal convoluted tubule, reducing sodium and chloride reabsorption and promoting diuresis. It also causes vasodilation by reducing peripheral vascular resistance.
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.
500 mg to 1000 mg orally or intravenously once or twice daily.
Oral: 25-50 mg once daily; may increase to 100 mg/day in divided doses if needed.

"The risk or severity of adverse effects can be increased when Chlorothiazide is combined with Digoxin."
Clinical Note
moderateTerminal half-life: 45–120 minutes (prolonged in renal impairment); clinical context: short duration requires frequent dosing
Terminal 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
Renal: ~95% (tubular secretion); Fecal: <5%
Primarily renal (approximately 85% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%)
