The Food and Drugs Authority (FDA) has sanctioned Samos Pharma's export partner, Aveo Pharmaceuticals, following a BBC Africa Eye investigation that exposed the company's alleged role in the illegal distribution of opioid-based medications across West Africa.

The sanction involved the revocation of the Good Manufacturing Practices (GMP) certification of the company.

It has further directed Samos Pharma, a Ghanaian importer, to terminate all transactions with Aveo Pharmaceuticals and Westfin International.

The FDA has also suspended the registration process for six products from Masters Pharmaceutical Limited, which planned to use Aveo Pharmaceuticals as a contract manufacturer.
