CHLORTHALIDONE vs ENDURON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide-like diuretic; inhibits sodium-chloride cotransporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water. Also lowers peripheral vascular resistance.
Thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and increasing water excretion.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.
Oral, 2.5–5 mg once daily. Maximum dose 10 mg/day.

Terminal half-life 40-60 hours (range 35-70h); prolonged in renal impairment
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 elimination half-life: 24-48 hours (mean 36 hours); prolonged in renal impairment or heart failure, allowing once-daily dosing.
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
Primarily renal (approximately 50-70% as unchanged drug); biliary/fecal (15-30%); dose adjustment required in renal impairment (CrCl <30 mL/min).
