In the qui tam case brought by Behn & Wyetzner, Chartered on behalf of whistleblower Lisitza, Lisitza alleged that CVS switched the drugs because the United States and various individual states had imposed price limits for the amounts that Medicaid would pay for the tablet form of ranitidine. By substituting capsules for tablets, CVS received substantially higher reimbursement amounts from various state Medicaid programs. The complaint states that the switches resulted in the government paying CVS as much as four times more for ranitidine capsules than for tablets.
