CHLORTHALIDONE vs DIURIL
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.
Inhibits sodium reabsorption in the distal convoluted tubule by blocking the sodium-chloride symporter, leading to increased excretion of sodium, chloride, and water.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.
Adults: 500 mg to 1000 mg orally once or twice daily; maximum 2000 mg per 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 is 6-15 hours (mean 10 hours). In renal impairment, half-life can exceed 24 hours.
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
Primarily renal (90-95% excreted unchanged via glomerular filtration and tubular secretion); minimal biliary/fecal (<5%).
