CHLORTHALIDONE vs DIULO
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 the Na+/Cl- symporter in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride, leading to increased diuresis and decreased extracellular fluid volume.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.
2.5 mg orally once daily, may increase to 5 mg once daily after 4 weeks if needed.

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 1.5-2 hours (mean 1.8 h) in healthy adults; prolonged to 3-6 hours in renal impairment and up to 8 hours in severe heart failure.
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
Primarily renal excretion (60-70% as unchanged drug) via glomerular filtration and tubular secretion; approximately 10-15% biliary/fecal elimination.
