Summary

Timolol maleate is recommended for glaucoma treatment due to its cost-effectiveness and efficacy. While other ocular beta-blockers offer some benefits, none consistently outperform timolol.

Area of Science:

  • Ophthalmology
  • Pharmacology

Background:

  • Glaucoma management relies on ocular hypotensive agents.
  • Ocular beta-blockers are a cornerstone therapy for lowering intraocular pressure.
  • Comparing these agents is crucial for optimizing patient care.

Purpose of the Study:

  • To compare ocular beta-blockers regarding efficacy, safety, and cost.
  • To identify key differences in systemic adverse effects and local tolerability.

Main Methods:

  • A comprehensive MEDLINE search and review of English-language literature.
  • Analysis of clinical trials focusing on dosage, response, adverse effects, and cost.
  • Evaluation of data based on study design and therapeutic outcomes.

Main Results:

  • Timolol maleate, levobunolol, metipranolol, and carteolol demonstrate similar intraocular pressure-lowering effectiveness.
  • Levobunolol and timolol gel formulations may allow once-daily dosing.
  • Metipranolol is cost-effective but associated with more ocular irritation; betaxolol offers better systemic safety than timolol.

Conclusions:

  • Timolol maleate is the recommended formulary agent for glaucoma.
  • No other ocular beta-blocker consistently shows a significant advantage over timolol in terms of cost, efficacy, and safety.
