SALUTENSIN-DEMI vs TIMOLIDE 10-25
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Salutensin-Demi is a combination of hydroflumethiazide, a thiazide diuretic that inhibits the Na+/Cl- symporter in the distal convoluted tubule, reducing sodium and water reabsorption, and reserpine, an adrenergic neuron-blocking agent that depletes catecholamines from peripheral nerve endings, reducing sympathetic outflow.
Timolol is a non-selective beta-adrenergic receptor antagonist that blocks beta-1 and beta-2 receptors, reducing heart rate, myocardial contractility, and blood pressure. Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium and water, reducing plasma volume and blood pressure.
1 tablet (15 mg hydrochlorothiazide + 0.075 mg clonidine) orally once daily, with titration based on blood pressure response.
One tablet (timolol 10 mg / hydrochlorothiazide 25 mg) orally once daily. May be increased to two tablets once daily if needed.

Hydrochlorothiazide: 6-15 hours (terminal), clinical effect lasts 6-12 hours; Reserpine: 50-100 hours (terminal), with prolonged action due to irreversible vesicular depletion
The terminal elimination half-life of timolol is approximately 4 hours in patients with normal renal function, but may be prolonged to 12-20 hours in patients with renal impairment or hepatic dysfunction. The half-life of hydrochlorothiazide is 6-15 hours.
Renal: hydrochlorothiazide 70% unchanged, reserpine <1% unchanged; fecal: reserpine ~6% as metabolites
Timolol is primarily eliminated by renal excretion of unchanged drug and metabolites. Approximately 20% of a dose is excreted unchanged in urine, with the remainder as metabolites (mostly inactive). Fecal elimination accounts for less than 5%.
