DOW JONES NEWSWIRES Valeant Pharmaceuticals International Inc.'s (VRX) buying spree continued Monday with the planned $180 million purchase of Natur Produkt International JSC, a Russian company which markets over-the-counter pharmaceuticals such as cough and cold remedies under the Natur Prodkt brand. Mississagua, Ont.-based Valeant said Natur Product generated about $65 million in revenue last year and is expected to deliver double-digit growth this year. It sees the purchase adding immediately to Valeant's earnings. The price may include an additional $5 million in potential future milestones. Earlier this month Valeant said it was acquiring, from Austria's Gerot Lannach, certain branded generics assets that generate the bulk of their sales in Russia. Monday, it said the acquisitions will bring Valeant's pro forma revenue in Russia to about $175 million by the end of 2012. -By Carolyn King, Dow Jones Newswires; 416-306-2100; carolyn.m.king@dowjones.com
