Pirenoxine

Pirenoxine (abbreviated PRX, trade name Catalin) is a medication used in the possible treatment and prevention of cataracts. A report in the journal of Inorganic Chemistry showed that in liquid solutions pirenoxine could cause decreased cloudiness of a crystallin solution produced to mimic the environment of the eye. Pirenoxine interacts with selenite or calcium ions that have been proven as factors leading to the formation of lens cataract.
