METHYCLOTHIAZIDE vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide-like diuretic that inhibits sodium-chloride symporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water. Reduces peripheral vascular resistance.
Trichlorex is a thiazide-like diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and increasing water excretion.
2.5-10 mg orally once daily.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

Terminal elimination half-life: ~40 hours (range 30-50 h); due to extensive tubular reabsorption, half-life is prolonged in renal impairment and elderly, allowing once-daily dosing
Clinical Note
moderateMethyclothiazide + Digoxin
"The risk or severity of adverse effects can be increased when Methyclothiazide is combined with Digoxin."
Clinical Note
moderateMethyclothiazide + Digitoxin
"The risk or severity of adverse effects can be increased when Methyclothiazide is combined with Digitoxin."
Clinical Note
moderateMethyclothiazide + Deslanoside
"The risk or severity of adverse effects can be increased when Methyclothiazide is combined with Deslanoside."
Clinical Note
moderateTerminal elimination half-life is 8-12 hours in adults; prolonged to 20-30 hours in severe renal impairment (creatinine clearance <30 mL/min).
Primarily renal (70-80% as unchanged drug via tubular secretion and glomerular filtration); minor biliary/fecal (<10%)
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
