In 2007, Apotex acquired a Belgian generic drug maker, Topgen ESV, from Zambon Group SpA of Italy as a way for Apotex to expand its European footprint. That same year, Apotex acquired Lareq Pharma SL of Spain from Industria Quimica Y Farmaceutica to extend the company's presence in Western Europe. In 2010, Apotex launched a generic version of Pfizer Inc.'s cholesterol-lowering Lipitor drug in Canada, after four years of patent litigation with Pfizer. Apotex's generic version was launched under the name of Apo-Atorvastatin. This saved provincial health programs over $800 million per year.
