A Glasgow pharmaceutical company is challenging a decision made by the DEA to suspend its registration.
Richie Pharmaceutical say they have done nothing wrong and are taking legal action to reverse the suspension.
The Drug Enforcement Agency suspended the federal controlled substance registration of the company last week.
The DEA said the Glasgow company was selling large amounts of controlled substances to internet pharmacies.
They say the investigation showed several of the company’s largest buyers of hydrocodone were distributing the drug to illigitimate prescriptions.
Richie Pharmaceutical will be given an opportunity for an administrative hearing.
After the hearing a final decision will be made on whether the company’s registration should be permanently revoked.
