What Is Dorzolamide/Timolol Used For?
The prescription eye drop dorzolamide/timolol is approved for the treatment of high eye pressure due to a specific type of glaucoma and ocular hypertension. This product is applied to the eye twice a day and helps reduce pressure by causing the eye to produce less fluid than normal. Children as young as two years old can use dorzolamide/timolol, and there is even one possible off-label use.
An Overview of Dorzolamide/Timolol UsesDorzolamide/timolol (Cosopt®) is a prescription eye drop used to lower the pressure in the eyes (intraocular pressure). Specifically, it is approved to lower eye pressure in people with the following conditions:
- Chronic open-angle glaucoma
- Ocular hypertension (high eye pressure that is not accompanied by changes in vision or damage to the optic nerve, as would happen with glaucoma).
As you might guess from the name, dorzolamide/timolol contains two separate active ingredients: dorzolamide (a carbonic anhydrase inhibitor) and timolol (a beta blocker). It is approved only for people who have not responded adequately to a beta blocker eye drop alone.
Not everyone with high eye pressure has glaucoma, although high eye pressure can lead to it. Effectively treating high eye pressure can help prevent glaucoma.
Glaucoma is not a single disease. It is actually a group of diseases sharing certain features, such as:
- High pressure within the eye (intraocular pressure)
- Damage to the optic nerve
- Loss of peripheral (side) vision
- Possible blindness.
Of all the different types, open-angle glaucoma is by far the most common (see Types of Glaucoma).
Although there is no cure for open-angle glaucoma, symptoms can usually be controlled and further damage may be prevented or reduced. The most common glaucoma treatments are:
- Traditional surgery (see Glaucoma Surgery)
- Medications (see Glaucoma Medications)
- Laser surgery (see Glaucoma Laser Surgery).
Dorzolamide/timolol can be taken by itself or, if necessary, combined with other types of medications or treatments.
