Benzalkonium Chloride + Brimonidine + Brinzolamide
Uses of Benzalkonium Chloride + Brimonidine + Brinzolamide
The primary use of Benzalkonium Chloride + Brimonidine + Brinzolamide is to manage intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. This combination medicine belongs to a group of eye medications known as antiglaucoma agents.
In addition to its primary use, this medication may also be used in conjunction with other IOP-lowering medications when single medicines do not sufficiently control IOP.

How Benzalkonium Chloride + Brimonidine + Brinzolamide works
Benzalkonium Chloride + Brimonidine + Brinzolamide belongs to the category of ophthalmic medications.
Benzalkonium chloride acts as a preservative, maintaining the sterility of the solution. It also assists with the penetration of the other ingredients into the eye due to its cationic surfactant properties.
Brimonidine, an alpha-2 adrenergic receptor agonist, works on two fronts. It reduces the production of aqueous humour, fluid in the eye, and enhances its outflow through a pathway known as uveoscleral outflow.
Brinzolamide reduces IOP by inhibiting carbonic anhydrase II, an enzyme found in the eyes. This action slows down the production of aqueous humour. This unique combination of actions from each component results in effective IOP reduction, helping to manage open-angle glaucoma and ocular hypertension effectively.
