Metipranolol is a medication used to treat high intraocular pressure due to glaucoma. There are several synonyms for Metipranolol, including Betamannodex, Betimol, Istalol, OptiPranolol, and Timoptic-XE. Betamannodex and Betimol are both brand names for the medication, while Istalol, OptiPranolol, and Timoptic-XE are brand names for different formulations of Metipranolol. These medications work by reducing the amount of fluid produced within the eye, which lowers intraocular pressure.
