Even as large as WebMD is, it would surprise me if they weren't using a third-party drug database to drive their public database. When I worked at a similar site, we used First DataBank [0], but there may be others too. The world of pharmaceuticals changes so rapidly that you need a small army of pharmacists and doctors scouring medical journals and materials from big pharma companies to keep your information up-to-date and it's just a lot easier to pay one of the dedicated companies that focus on that to do that work for you. However it wouldn't surprise me if the NHS took on that task itself. Unlike WebMD, the NHS is also responsible for prescribing medications and would need to give their doctors and pharmacists up-to-date information, software and guidance for prescribing. Their scale and scope would allow them to take on this task in a way that makes less sense in the US system, where insurance providers, doctors, pharmacies and online health information are all separate entities with separate budgets/funding.
