These Regulations amend the Branded Health Service Medicines (Costs) Regulations 2018 (S.I. 2018/345) (the “Statutory Scheme Regulations”). The Statutory Scheme Regulations, amongst other matters, make a scheme for the purpose of requiring specific manufacturers and suppliers of branded medicines for health service use to pay certain amounts to the Secretary of State. These amounts are calculated by reference to the net sales income or estimated net sales income from supplies of such medicines.
