Perrigo to buy Elan Corp.
ALLEGAN, Mich. — U.S.-based drug maker Perrigo Co. will buy Ireland's Elan Corp. for $8.6 billion, the companies said Monday.
Elan is best known for the multiple sclerosis treatment Tysabri (natalizumab), marketed and distributed by Biogen Idec. Perrigo manufactures various branded and generic prescription and OTC drugs. A previously announced deal, whereby New York-based Royalty Pharma would acquire the Dublin-based drug maker, fell apart last month after Elan shareholders voted in favor of a share-buyback plan.
