CHLORTHALIDONE vs HYDRO-RX
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.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption, leading to increased diuresis, decreased plasma volume, and vasodilation. It also reduces peripheral vascular resistance.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.
Initial: 25 mg orally once daily; may increase to 50 mg once daily after 2 weeks based on response. Maximum: 50 mg daily.

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
Terminal elimination half-life is 8-12 hours in adults with normal renal function; extended to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
Renal excretion of unchanged drug accounts for 60% of elimination; biliary/fecal excretion accounts for 30%; 10% metabolized.
