As you probably already know, it seems to have dropped out of sight.
The newest reference in the U.S. National Library of Medicine (PubMed)
dates back to 1995.  Even searching Google gave no recent references.
Searching the Aventis site produced nothing and it is not listed under
the pharmaceuticals they produce.

Perhaps it turned out to be too expensive, with too many side effects,
and not more effective than other treatments and so was dropped.
