BLOCADREN vs TIMOPTIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective beta-adrenergic receptor antagonist; blocks beta-1 and beta-2 receptors, reducing heart rate, myocardial contractility, and blood pressure.
Non-selective beta-adrenergic receptor antagonist (beta-blocker). Reduces intraocular pressure by decreasing aqueous humor production, likely via blockade of beta-2 receptors in the ciliary epithelium.
Hypertension: initial 10 mg PO twice daily, increase gradually to 20-40 mg/day; maximum 60 mg/day. Post-MI: 10 mg PO twice daily starting 1-4 weeks post-infarction.
One drop of 0.25% or 0.5% solution in the affected eye(s) twice daily.

Terminal elimination half-life: 12-15 hours; prolonged in renal impairment (up to 24 hours) and elderly; dose adjustment required in CrCl <35 mL/min
Terminal elimination half-life is approximately 4-6 hours in healthy adults; prolonged in renal impairment.
Primarily renal (80-95% unchanged), minor hepatic metabolism to inactive metabolites, minimal fecal excretion (<5%)
Renal elimination: ~20% unchanged; biliary/fecal elimination: ~80% as metabolites.
