Texas attorney general **Ken Paxton** has reached a $41.5 million settlement with Pfizer and Tris Pharma after accusing the companies of providing adulterated ADHD medication to children enrolled in the state’s Medicaid program. The agreement resolves a [lawsuit](https://www.texasattorneygeneral.gov/news/releases/attorney-general-ken-paxton-sues-pfizer-and-tris-pharma-defrauding-texas-medicaid-and-providing?ref=fdaweb.com) Paxton filed 11/2023, alleging that the companies knowingly distributed Quillivant XR — an extended-release methylphenidate formulation — to Medicaid patients despite repeated failures in quality-control testing. The complaint claimed that from 2012 to 2018, Pfizer and Tris altered laboratory testing methods to mask manufacturing issues and keep the drug on the market, in violation of both federal and state law, including the Texas Health Care Program Fraud Prevention Act.

Paxton said the settlement demonstrates his office’s willingness to pursue large pharmaceutical manufacturers for misconduct affecting vulnerable populations. “Pfizer and Tris Pharma provided adulterated drugs to children for years and changed test results in order to obtain the benefit of taxpayer-funded Medicaid reimbursement,” he said. “Under my watch, Big Pharma will not escape justice for lying about the effectiveness of its drugs.”

As part of the settlement, Pfizer and Tris have agreed to comply with all relevant state and federal drug manufacturing and distribution regulations. The companies did not admit wrongdoing under the terms of the agreement.
