INDERIDE LA 120/50 vs TRASICOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Propranolol is a nonselective beta-adrenergic receptor antagonist that blocks beta-1 and beta-2 receptors, decreasing heart rate, myocardial contractility, and blood pressure. Hydrochlorothiazide is a thiazide diuretic that inhibits the Na+/Cl- symporter in the distal convoluted tubule, reducing sodium reabsorption and promoting diuresis.
Non-selective beta-adrenergic antagonist with intrinsic sympathomimetic activity (partial agonist) at beta-1 and beta-2 receptors, reducing heart rate, myocardial contractility, and blood pressure.
One capsule orally once daily, containing 120 mg propranolol HCl and 50 mg hydrochlorothiazide.
20-40 mg orally three times daily, increased to 80-160 mg daily if needed; maximum 320 mg/day.

Propranolol: 3-6 hours; Hydrochlorothiazide: 6-15 hours. Note: Inderide LA is an extended-release formulation; effective half-life extended to approximately 8-12 hours for propranolol component.
Terminal elimination half-life is approximately 8-12 hours in patients with normal renal function; may be prolonged in renal impairment, requiring dose adjustment.
Primarily hepatic metabolism (90%+), with <5% excreted unchanged in urine. Biliary/fecal elimination accounts for negligible amounts.
Renal excretion of unchanged drug and metabolites accounts for approximately 80% of elimination, with about 20% appearing as unchanged drug; biliary/fecal excretion accounts for the remaining 20%.
