The MHRA publishes FOI responses almost every week — what that reveals about medicines regulation requests

Medicines & Regulation is the largest single topic in our health tracker: 161 releases, the great majority from the Medicines and Healthcare products Regulatory Agency (MHRA) — the UK's regulator for medicines and medical devices.

A weekly rhythm, not a monthly one

Most publishers in our dataset disclose in monthly or quarterly batches. The MHRA is unusual: its releases are titled "Freedom of Information responses from the MHRA — week commencing [date]", one per week, going back years. That cadence alone tells you something about the volume of FOI traffic a medicines regulator receives — it's high and steady enough to justify a weekly, rather than monthly, publishing rhythm, which is rare in this dataset.

It also produces an artefact worth flagging honestly: batches of these weekly releases sometimes get published to GOV.UK on the same day, in bulk, well after the "week commencing" date in the title. That's a publisher clearing a backlog of write-ups, not a real-time feed — the same caution about reading gaps and spikes literally applies here too (our companion Policing & Justice tracker has a good example of this in its piece on a nine-month publishing gap).

What's actually being asked

Medicines regulation FOI requests, going by the pattern in titles and descriptions we can see, cluster around a few recurring themes: licensing and approval status of specific drugs, adverse event and safety reporting, clinical trial authorisations, and — more recently — vaccination programme logistics. It's a technical, specialist-heavy topic area: a meaningful share of requesters asking the MHRA appear to be industry, legal, or research-affiliated rather than general public interest, based on the specificity of what's asked (particular product licence numbers, particular trial identifiers).

Why the MHRA and not "the NHS"

Worth repeating here what we say on our about page: the MHRA is a regulator, not a care provider — it doesn't run hospitals or treat patients. It's the single largest source in our health dataset precisely because GOV.UK's FOI feed is a central-government channel, and medicines regulation is a central-government function in a way that day-to-day hospital care isn't. See our companion piece on why most NHS trusts aren't in this dataset at all for the rest of that picture.
