ALLEGAN, Mich. – Perrigo Co. has begun rolling out minoxidil 5% foam to its retail and wholesale customers. The company said Thursday that the product, marketed under store brands or own-label brands, is comparable to Rogaine 5% Foam Hair Regrowth Treatment. Perrigo had announced in May that it received final approval from the Food and Drug Administration for its abbreviated new drug application for the over-the-counter minoxidil foam. Rogaine 5% Foam is a treatment for the regrowth of hair on the top of the scalp, and the product's estimated annual sales are about $60 million, according to Perrigo. Just over a year ago, Perrigo announced that it successfully settled its Hatch-Waxman litigation relating to minoxidil 5% foam brought by Stiefel Research Australia Pty. Ltd., a GlaxoSmithKline company. Perrigo said that since it was the first party to challenge the brand patent, it's entitled to 180 days of generic marketing exclusivity.
