Clinical Effects of Unoprostone Ophthalmic Solution
Eye pressure is measured in millimeters of mercury (mmHg). In clinical studies, unoprostone ophthalmic solution was shown to reduce eye pressure by 3 to 4 mmHg in people with an average eye pressure of 23 mmHg. An eye pressure over 22 mmHg is considered higher than normal.
Medications used to lower eye pressure usually work by either decreasing the amount of fluid produced in the eye (known as the aqueous humor) or by increasing drainage of the aqueous humor from the eye. Unoprostone ophthalmic solution is thought to work by increasing fluid drainage from the eye.
More specifically, the drug may open certain channels in the trabecular network, a sponge-like tissue in the eye that is responsible for draining aqueous humor from the eye. However, the exact way in which unoprostone ophthalmic solution works to reduce intraocular pressure is unknown.
