Mechanism of action

This a beta-1 selective beta blocker that reduces the aqueous humor production, increases drainage, and alters the blood flow of the eye, thus lowering the pressure.

Treatment of open angle glaucoma and ocular hypertension.

Dosage

Instill 1 drop of the 0.25% solution into eye every 12 hours twice every day. Increase to 0.5% solution if needed. Decrease to 1 drop every day if condition is controlled. Consult your doctor for the correct dosage.
