Perrigo gets OK for generic men’s Rogaine foam

ALLEGAN, Mich. — The Food and Drug Administration has approved a generic version of Rogaine made by Perrigo, the drug maker said.

Perrigo announced the FDA approval of over-the-counter minoxidil foam, a generic version of men’s Rogaine foam.

Stiefel Research Australia, part of GlaxoSmithKline, sued Perrigo for patent infringement when the latter submitted its regulatory approval application. Under a settlement between the companies reached in February, Perrigo can launch its generic version of men’s Rogaine foam in March 2012.

Rogaine foam has annual sales of about $60 million, according to SymphonyIRI Group.
