RENESE-R vs TIMOLIDE 10-25
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic; inhibits sodium-chloride symporter in distal convoluted tubule, reducing sodium and water reabsorption.
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.
Initial: 5 mg orally once daily, increased as needed to 10 mg once daily; maximum 10 mg/day.
One tablet (timolol 10 mg / hydrochlorothiazide 25 mg) orally once daily. May be increased to two tablets once daily if needed.

Terminal elimination half-life: 13-16 hours; clinical context: supports once-daily dosing
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: 50% unchanged; fecal: 0%; biliary: 0%
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%.
