The discontinuation data is the most under-discussed part of this entire class
Everyone quotes the efficacy numbers. Almost nobody quotes what happens after stopping.
The published withdrawal and extension data across this class shows substantial regain following discontinuation — a large fraction of what was lost, over a timeframe of about a year.
This isn't a criticism of the drugs. It's arguably what you'd expect if the mechanism addresses an ongoing regulatory process rather than producing a permanent change. Stopping an antihypertensive returns blood pressure too, and nobody considers that a failure of the drug.
But it does reframe what these are. They look like ongoing management rather than a course of treatment, and that has consequences for cost, adherence, supply and how people plan.
Evidence tier: randomised withdrawal and extension phases of registered trials. Human data, reasonably strong.
I think the reason this gets skipped is that it makes the story less exciting. Which is exactly why it's worth saying.
