Key result
Topically instilled 0.25% betaxolol hydrochloride produced a significant 30% to 35% decrease in intraocular pressure below baseline over a one-year period.
Why the study?
Does topically instilled 0.25% betaxolol hydrochloride reduce intraocular pressure in patients with chronic open angle glaucoma or ocular hypertension?
Does topically instilled 0.25% betaxolol hydrochloride reduce intraocular pressure in patients with chronic open angle glaucoma or ocular hypertension?
Topical 0.25% betaxolol significantly lowers intraocular pressure without adverse systemic cardiovascular effects, suggesting clinical potential for glaucoma treatment.
May support topical betaxolol for IOP reduction in glaucoma; hypothesis-generating case report requiring RCT validation.
The intraocular pressure response to topically instilled 0.25% betaxolol hydrochloride was evaluated in 12 patients with chronic open angle glaucoma or ocular hypertension. The drug produced a significant lowering of IOP in all 12 of the patients under study. A 30% to 35% decrease below baseline IOP was observed and was maintained during the one-year observation period. Visual acuity was stable in all subjects throughout the study and corneal anesthesia was not encountered. Tear secretion was not adversely effected by betaxolol, nor did topical administration of the drug produce any systemic cardiovascular response of consequence. Blood pressure and pulse rate remained stable throughout the year. These data suggest that an ophthalmic formulation of betaxolol may have substantial clinical potential for the treatment of glaucoma.

Amado R. Berrospi (1982) studied chronic open angle glaucoma or ocular hypertension (n=12). betaxolol hydrochloride was evaluated on intraocular pressure (IOP) response (30% to 35% decrease below baseline). Topically instilled 0.25% betaxolol hydrochloride produced a significant 30% to 35% decrease in intraocular pressure below baseline over a one-year period.
