What is Azopt (Brinzolamide)?

Azopt is a prescription medication that consists of a 1% liquid solution of Brinzolamide that comes in either 10mL or 15mL dropper bottle. This means that each mL of solution contains 10mg of the active, generic drug Brinzolamide. This is the only strength available. It is approved by the FDA to treat ocular hypertension and open-angle glaucoma by reducing the pressure inside the eye.

How does it work?

It works by inhibiting carbonic anhydrase, an enzyme that increases secretion by the aqueous humor of the eye. By preventing this enzyme from working, it reduces the amount of fluid produced by the eye and this then reduces the pressure inside the eye. Increased pressure in the eye can cause pain and if left untreated can permanently damage vision.

How to use Azopt

Eye drops can be administered alone or with the help of someone else.

Remove any contact lenses before applying eye drops. A preservative in this medicine can cause staining of soft contact lenses. Any contact lenses can be replaced 15 minutes after administration of medication.

Shake the bottle before use.

  1. Wash your hands and dry thoroughly.
  2. Remove the cap and place in a clean area.
  3. Tilt your head back and gently pull down on the lower lid of the affected eye.
  4. Using your other hand, apply one drop to the space created by pulling down on the lower lid.
  5. Do not touch the eye or the skin with the tip of the dropper. A contaminated dropper could result in an infection of the eye.
  6. Repeat with the other eye if advised to do so by your doctor.
