Medco Health Solutions, another one of the big three prescription benefit managers, has announced that it will begin dispensing Apotex’s generic version of the anti-blood clotting drug Plavix tomorrow. According to Marketwatch.com, “Medco members account for 24% of Plavix’s U.S. market share, and more than half of Medco’s Plavix prescriptions are filled through the company’s mail-order pharmacies.” Apotex evidently is trying to flood the market with the generic drug before the brand name manufacturers can get to court under an earlier settlement agreement.
