Levobunolol for the long-term treatment of glaucoma.

Systemically, levobunolol is as effective as propranolol for cardiovascular indications, with a greater potency and greater duration of action. Ocularly, levobunolol is as effective and as safe as topical timolol for the long-term treatment of elevated IOP. The utility of topical levobunolol as an additional, effective beta-blocker for the treatment of glaucoma will be determined by additional research and use by ophthalmologists in countries where levobunolol is approved.
