Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium-chloride symporter in distal convoluted tubule of nephron, reducing sodium reabsorption and promoting diuresis.
Thiazide-like diuretic; inhibits sodium-chloride cotransporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water. Also lowers peripheral vascular resistance.
500 mg to 1 g orally or intravenously once or twice daily.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.

Terminal elimination half-life is 45–120 minutes in patients with normal renal function; prolonged in renal impairment (up to 24 hours in anuria).
Clinical Note
moderateChlorthalidone + Digoxin
"The risk or severity of adverse effects can be increased when Chlorthalidone is combined with Digoxin."
Clinical Note
moderateChlorthalidone + Digitoxin
"The risk or severity of adverse effects can be increased when Chlorthalidone is combined with Digitoxin."
Clinical Note
moderateChlorthalidone + Deslanoside
"The risk or severity of adverse effects can be increased when Chlorthalidone is combined with Deslanoside."
Clinical Note
moderateTerminal half-life 40-60 hours (range 35-70h); prolonged in renal impairment
Primarily renal excretion via tubular secretion; approximately 95% of absorbed dose excreted unchanged in urine within 24 hours, with less than 5% eliminated via bile/feces.
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
