Request

We understand that Merbentyl Syrup 10 mg/5 ml was initially granted marketing authorisation to Aventis Pharma Limited under PL No. PL 04425/0047. Subsequently, the ownership of the product appears to have been transferred to Winthrop Pharmaceuticals UK Limited under PL No. PL 17780/0564. As Merbentyl Syrup 10 mg/5 ml is currently not available on the UK market, we kindly request your confirmation of the current Marketing Authorisation Holder (MAH) for this product, along with the corresponding PL number.
