General Information on DuoTrav Eye Drops
DuoTrav Eye Drops are used in the treatment of open angle glaucoma. The generic name of this drug is Travoprost - Timolol Eye Drops. As it is a prescription drug, you can buy DuoTrav Eye Drops only if your doctor has prescribed the drug for your treatment.
DuoTrav Eye Drops includes two active ingredients, timolol maleate and travoprost. Both these active ingredients reduce abnormally high pressure within the eye. The working mechanism of these two ingredients, however, is different, even though their combined strength is far more effective against open angle glaucoma.
Aqueous humour, a thick naturally-occurring liquid, maintains pressure within the eye. When the production of this liquid is above normal or when the flow of this liquid is curbed, the pressure within the eye increases. Prostaglandins, a naturally occurring chemical, plays an important role in draining aqueous humour from the eye. Travoprost is a prostaglandin analogue, that is, it mimics the action of Prostaglandins and helps remove excess aqueous humour from the eye. This, in turn, reduces the pressure within the eye.
Timolol, a beta-blocker, reduces the production of aqueous humour. It achieves this by blocking the activity of certain chemicals that play an important role in the production of aqueous humour.
In addition to the two aforementioned ingredients, DuoTrav Eye Drops also contain the following excipients: polyquaternium-1, polyoxyethylene hydrogenated castor oil 40, sodium chloride, boric acid, mannitol, purified water, propylene glycol, and hydrochloric acid and/or sodium hydroxide for maintaining pH.
