very true. As far as I'm aware, current plans are for MHRA & VMD to fast-track newly approved EU humans and veterinary medicines if an application applies for a UK license. Whether its worth a company doing this will depend on the potential market share, negotiated reimbursement price and cost of setting up / maintaining a UK specific operation. All the mutual recognition scheme for products licensed in the rest of EU will all dry up as we become a third party country
I imagine what will happen is MAHs will drop their UK licences. That way they won't have public or product liability, won't have UK pharmacovigilance responsibilities and will be unshackled from UK price constraints. What that means for the availability and prices of Certan and other bee husbandry products lord only knows.
