ReplyThe NHS Business Services Authority (NHS BSA) produces official statistics on Prescription Cost Analysis (PCA) which show the total volume and cost for drugs, dressings, appliances, and medical devices that have been dispensed in the community in England. These statistics cannot be specifically linked to the marketing authorisations, but they can be linked to pharmaceutical product suppliers using the NHS Dictionary of Medicines and Devices. Suppliers may be distributors, manufacturers, or wholesalers.

In cases where the NHS BSA has no supplier information, these items are classified as ‘Generic Supplier’.As set out in the answer I gave on 23 July 2025 to Question 68960, we do not hold prescribing data that specifically differentiates inhalers based on whether they have dosage counters. We note, however, that most dry powder inhalers have dosage counters, whilst most pressurised inhalers do not. In June 2025 the proportion of salbutamol and terbutaline sulphate inhalers that were dry powder inhalers was 9.3%.
