CLEVELAND (AP) — Federal authorities say two Ohio doctors prescribed a drug to patients who didn’t need it as part of a kickback scheme involving two drug company employees.

The U.S. Attorney’s Office in Cleveland says the physicians along with representatives from California-based Avanir Pharmaceuticals engaged in a conspiracy that saw the doctors prescribing Nuedexta to patients not suffering from pseudobulbar affect, a condition marked by involuntary and frequent episodes of laughing or crying.

Prosecutors said Thursday that one of the physicians earned more than $330,000 between 2011 and 2016 giving presentations at high-end restaurants and doctors’ offices while writing 10,000 Nuedexta prescriptions, highest in the country.

Prosecutors say the other physician received free firearms training, office equipment and other things of value.

Avanir says the representatives no longer work for the company.
