CHLORTHALIDONE vs METHYCLOTHIAZIDE AND DESERPIDINE
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.
Methyclothiazide is a thiazide diuretic that inhibits sodium reabsorption in the distal convoluted tubule, reducing plasma volume; deserpidine is a Rauwolfia alkaloid that depletes catecholamines from peripheral sympathetic nerve endings, lowering 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.
One tablet (5 mg methyclothiazide / 0.25 mg deserpidine) orally once daily. Maximum dose: one tablet daily.

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
Methyclothiazide: terminal half-life 17-24 hours, permitting once-daily dosing. Deserpidine: 50-100 hours, allowing accumulation with repeated dosing.
Renal: 50-65% unchanged; biliary/fecal: minimal (<5%)
Methyclothiazide: primarily renal excretion (60-70% unchanged) via tubular secretion; Deserpidine: extensive hepatic metabolism, <1% excreted unchanged in urine, with metabolites excreted in urine (40%) and feces (60%).
