Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Timolol is a non-selective beta-adrenergic receptor antagonist (beta-1 and beta-2) that reduces intraocular pressure by decreasing aqueous humor production, likely by blocking beta-adrenergic receptors in the ciliary epithelium.
Timolol is a nonselective beta-adrenergic receptor antagonist that blocks beta-1 and beta-2 adrenergic receptors. In the eye, it reduces aqueous humor production by inhibiting beta-2 receptors in the ciliary epithelium, thereby lowering intraocular pressure.
Instill 1 drop of 0.25% or 0.5% solution in the affected eye(s) twice daily.
Instill one drop of 0.25% or 0.5% solution in the affected eye(s) once daily in the morning.

Terminal elimination half-life is 4-6 hours in adults; prolonged to 8-12 hours in renal impairment.
Plasma: 4-6 hours; prolonged in renal impairment. Systemic half-life after ocular dosing: 4-5 hours.
Renal: approximately 80% as unchanged drug and metabolites; biliary/fecal: minor (less than 10%).
Renal: 20% unchanged; remainder as metabolites via urine. Minor biliary/fecal elimination.
