Heres a link with a lot of info on ferret drugs:

Also, if you haven't read the information below about insulinoma,
it's VITAL that you do so. It is a serious disease that you need to
understand fully in order to manage it:

Your best place to start for info is this article by Dr. Bruce
Williams:

And then here, from Mike Janke's site:

And here is a quote from a study by Dr. Williams and others that
concludes that the most effective treatment is surgery to get rid
of visible nodules AND part of the pancreas:

Insulinoma in the ferret: clinical findings and treatment
comparison of 66 cases.

Weiss CA,
Williams BH,

Potomac Animal Hospital, Maryland 20854, USA.

The clinical signs and surgical findings were reported for 66 ferrets
with insulinomas confirmed histologically. All of the ferrets were
treated with one of three modalities, and disease-free intervals and
survival times were gathered to determine the most effective treatment.
The three treatment groups included 10 ferrets treated medically, 27
ferrets treated with pancreatic nodulectomy, and 29 ferrets treated
with pancreatic nodulectomy combined with a partial pancreatectomy. The
mean disease-free intervals for each group were 22, 234, and 365 days,
respectively. The mean survival times for each group were 186, 456, and
668 days, respectively. Based upon the data, recommendations were made
for treating insulinoma in the ferret.

There is also much other info online, but these were, in my opinion,
the best places to start.
