Executive Summary

Perrigo ships its generic of Novartis Pharmaceuticals' Zaditor, a ketotifen fumarate ophthalmic solution, .025 percent, the Allegan, Mich.-based private labeler says in a March 15 release. Perrigo CEO Joseph Papa said the firm is "excited to launch into a new adjacent OTC category, ophthalmics." Zaditor is a solution used to temporarily prevent allergic conjunctivitis. Wolters Kluwer data estimates the annual sales of Zaditor in the last 12 months reached $15 million, Perrigo said.
