INDERIDE-80/25 vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
INDERIDE-80/25 is a combination of propranolol (a non-selective beta-adrenergic receptor antagonist) and hydrochlorothiazide (a thiazide diuretic). Propranolol blocks beta-1 and beta-2 adrenergic receptors, reducing heart rate, myocardial contractility, and renin release, thereby lowering blood pressure. Hydrochlorothiazide inhibits the sodium-chloride symporter in the distal convoluted tubule of the kidney, increasing excretion of sodium, chloride, and water, reducing plasma volume.
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.
One tablet (80 mg propranolol/25 mg hydrochlorothiazide) orally twice daily.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

Propranolol: 3-6 hours (single dose), prolonged with chronic dosing (up to 12 hours). Hydrochlorothiazide: 6-15 hours; prolonged in renal impairment.
Terminal elimination half-life is 8-12 hours in adults; prolonged to 20-30 hours in severe renal impairment (creatinine clearance <30 mL/min).
Renal: 40% unchanged propranolol; 60% as metabolites. Biliary/fecal: minimal (less than 1%). Hydrochlorothiazide: renal 95% unchanged.
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
