But as I said, these will be recognised as a different formulation, so
any generic version of the original will not be equivalent. This can
be used to extend the life of a product - one notable example was
Glaxo's Zantac, for gastric ulcers and similar, which was due to go
off-patent in the late 1990s. At this point it became legal for anyone
to manufacture and sell generic versions of it, which would, of
course, dramatically hit sales.

By that time, however, Glaxo had, developed a new coating which both
significantly increased its tolerability - an important aspect for
stomach problems - and allowed lower doses to be as effective. They
were then able to extend the patent life by having the new formulation
licensed as a new drug.

The old version did still go generic though didn't it? And, I'd imagine
that has still hit sales.

AFAIK generic Ranitidine (Zantac) is pretty much the default thing NHS
doctors prescribe for that type of thing these days.
