In theory of course a use patent is available for new ideas for an old drug. But that is often a very slender reed to base a business on - there have been few successful examples I can think of where a use patent was the only protection for a new use of an existing marketed drug.

One was CollaGenex with low-dose doxycycline - but there they had some added protection for a while because there was no generic with the approved dose. But some generic eventually launched against them anyhow.

Nitrobid is another example of a failure, although there it is unclear whether doctors are in fact prescribing the generic components separately.
