Pirenoxine is an agent with anti-cataractogenesis activity by interacting with calcium ions or selenite which could lead to the formation of lens cataract.

Small volumes of Pirenoxine, inhibitor vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
