Risperdal Pharma Company Sued for Obfuscating Negative Studies

A large pharmaceutical company was litigated against after they allegedly covered up the potential harmful side effects of the antidepressant Risperdal. The case claimed that the company had obscured evidence that the risperidone in Risperdal increased prolactin and caused gynecomastia in many of its patients. The case hinged on an early version of a company-run study that traced a link between increased prolactin levels and the onset of gynecomastia. These findings were allegedly obscured from the final paper, and an expert in statistics was needed to review the original report and re-analyze the data to determine whether or not the company should retract its research paper.
