In the latest struggle over pharmaceutical costs, Pfizer has filed a lawsuit against a Texas state agency for releasing Medicaid rebate data to a pair of state lawmakers, claiming the move violated federal and state laws that protect its confidential information.

By releasing the data, Pfizer argued the Texas Health and Human Services Commission compromised “valuable and commercially sensitive trade secrets” that could hurt its ability to compete with rivals, according to the lawsuit, which was filed in federal court in Austin, Texas, on Thursday. “Small differences in pricing and rebates can make the difference between success and failure,” the lawsuit stated.


The drug maker also contended that disclosure can lead to “uniform pricing” that could harm Medicaid. How so? Pfizer maintained that, if other large purchasers were to know about — and then demand — the same prices offered to the Texas Medicaid program, the company “would not be able to provide such pricing and rebates to every entity due to their unique differences in size, market and particular needs.”
