Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide-like diuretic that inhibits sodium-chloride cotransport in the distal convoluted tubule, increasing excretion of sodium, chloride, and water.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, reducing sodium and water reabsorption. Reserpine depletes catecholamines from central and peripheral nerve terminals by inhibiting vesicular monoamine uptake, leading to decreased sympathetic outflow.
Oral, 50 mg once daily, increased to 100 mg once daily if needed.
1 tablet orally once daily, each tablet contains hydrochlorothiazide 25 mg and reserpine 0.125 mg. Dosage may be increased to 2 tablets daily if needed.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function; may be prolonged in renal impairment.
Hydrochlorothiazide: 6-15 hr; reserpine: 50-100 hr (terminal, with prolonged adrenergic depletion lasting days)
Renal: approximately 70% as unchanged drug; biliary/fecal: approximately 30% as unchanged drug and metabolites.
Renal: hydrochlorothiazide 70% unchanged, reserpine ~30% unchanged; fecal: reserpine ~60% metabolites
