Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
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.
Instill 1 drop of 0.5% solution in the affected eye(s) twice daily.
One capsule orally once daily, containing 120 mg propranolol HCl and 50 mg hydrochlorothiazide.

Terminal elimination half-life: 4–5 hours. With topical ophthalmic administration, systemic absorption is minimal, so half-life refers to IV data.
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.
Renal (fecal <5%). 60% as unchanged drug, 40% as inactive metabolites.
Primarily hepatic metabolism (90%+), with <5% excreted unchanged in urine. Biliary/fecal elimination accounts for negligible amounts.
