🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking beta-adrenergic receptors in the ciliary epithelium of the eye. This action reduces the production of aqueous humor, the fluid that fills the front part of the eye. By decreasing the formation of this fluid, the pressure inside the eye is lowered. Unlike some other glaucoma medications, it does not affect the drainage of fluid out of the eye. The exact mechanism by which beta-blockers reduce aqueous humor production is not fully understood, but it is believed to involve inhibition of cyclic AMP production.
