CHLORTHALIDONE vs NAQUA
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.
Inhibition of sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, reducing sodium and chloride reabsorption and promoting diuresis.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.
Oral: 5-10 mg once daily, preferably in the morning. Maximum dose 20 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 is 6-12 hours; prolonged in renal impairment (up to 20-30 hours) or heart failure due to reduced renal perfusion.
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
Primarily renal elimination; approximately 60-80% excreted unchanged in urine via tubular secretion; minor biliary/fecal excretion (<10%).
