Medication list and doses

Hi,
We are building an application that generates dynamic forms for ordering
various tests in a medical application. We want to have the ability to
also
choose medications and appropriate doses from the thousands of
medications
that are available. Does anyone know of a library or module that has
been
built using Rails to order medications and their appropriate doses,
rather
than us creating one.

Thanks
