The medicine is a cardioselective blocker of beta-1-adrenergic receptors. A major risk index for glaucomatous scotoma is an increased tension. When its rate is soaring, the eyes are more damaged. As a consequence, a visual field narrows. Betoptic reduces both increased and usual pressure, regardless of if it occurs with glaucoma, or not; the structure of its activity is connected with a decline in the performance of intraocular fluid. Betaxolol acts after half-an-hour, and the expected result is normally achieved after 2 hours after application.

Betoptic is a pharmaceutical product with beta-blocking properties used to reduce an elevated ocular pressure. It is applied in treatments of open-angle glaucomas and other disorders associated with abnormal pressure in the eye.
This ophthalmic preparation may be prescribed along with other eye treatments. Refrain from using ophthalmic action products on your own initiative unless those pharmaceuticals were prescribed for you by a qualified doctor. If you want to combine betaxolol with various eye drops, maintain a minimum spacing of 10 minutes between the applications. Such medications should not be co-administered simultaneously.
Betopic may cause blurred or unclear vision. Consider this in case you are going to drive or perform a task requiring you to see well. This drug does not combine with contact lenses. Its composition can include preservatives able to be absorbed by the soft structure of the lenses. Do not put your lenses on sooner than 15 minutes following the application of Betoptic.
Directions for use
One drop of the ophthalmic suspension of Betoptic in a concentration of 0.5% should be instilled in the problematic eye two times a day.
For correct application of the eye drops:
- Lean your head back a bit and carefully pull down the bottom eyelid. Turn the dispenser down right above the eye so that drops may be instilled. Squeeze out a single drop, then shut your eyes.
- Apply gentle pressure on the eye’s inside corner with your index finger for approx. 1 minute to keep the fluid from flowing out. You cannot instill another drop (if you need to) until 5 minutes after the first one.
- Protect the dropper tip from touching anything to exclude the risk of infectious particles getting in and development of further eye infection.
