How Does Xalatan Work?

Xalatan belongs to a group of medications known as prostaglandins. Medications to lower eye pressure usually work by either decreasing the amount of fluid produced in the eye or by increasing the fluid drainage out of the eye. Either way, the result is the same -- lower eye pressure.
Xalatan works by opening the channels that drain fluid from the eye. By reducing eye pressure, the medication can help prevent damage to the optic nerve (and the vision loss that accompanies such damage) caused by high eye pressure.
