> Everyone has heard of "mission creep." In the pharmaceutical world, approval creep means getting the FDA to approve a drug for one thing and pushing a lot of other drug approvals through on the coattails of the first one.
This is more accurately referred to as "drug repurposing," and it's hardly the unalloyed evil that it's characterized as here. It's true that drug companies love to repurpose existing FDA-approved drugs, both because it saves them money and because it typically permits them to patent the compound again in a new context, but there are nonetheless real benefits to the public at large when a drug whose side effects are comparatively well-characterized over the long term is put into service to treat a different malady.
