    Alphagan P (Brimonidine) Product information

    Alphagan P is similar to Alphagan in that it is prescribed to patients suffering from open angle glaucoma, or ocular hypertension. The medications are different however, as Alphagan P contains the preservative Purite, rather than the most common preservative found in eye drop medications: benzalkonium chloride.

    Also known as Brimonidine, is a treatment for increased eye pressure, and it's function is to lower the amount of fluid in the eye. This medication is usually placed in a group of drugs called adrenergic agonists or alpha agonists.

    Alpha agonists attach to and activate alpha receptors inside the eye, in result, the aqueous humor (eye fluid) reduces and the rate of drainage increases, lowering the pressure in eyes.
