How the Medication Works:
Lowers the pressure within the eye by reducing the amount of fluid (aqueous humor) secreted into the eye. The pressure within the eye is decreased as a result of less fluid production.
Directions for Taking the Medication:
One eye-drop, twice a day (morning and evening). In certain cases the medication is given 3 times a day.
Advantages of this Medication:
It has replaced the need, for most patients, to take pills such as Diamox, Uramox, or Neptazane. This medication, administered as eye-drops, has much fewer side-effects than do the pills mentioned above.
Family of Medication:
Carbonic anhydrase inhibitors.
Eye-drops which belong to the group of carbonic anhydrase inhibitors have limited systemic effects. The most common side-effects of these drops are a bitter (metallic) taste in the mouth, changes in the sense of taste, and local irritation and redness of the eye.
This group of medications (albeit in pill form) has been in use for the treatment of glaucoma for decades. However, eye-drops that belong to this group (Trusopt) have only been available for the past few years. When instilling these drops, the patient will likely feel a strong burning sensation that may last 10 seconds or slightly more. This is a normal phenomenon and not a side-effect.
