I'm an ER doctor myself and was wondering whether the--onetime standard--therapy for intermittent claudication, the drug pentoxifylline (Trental®) was still on the market? It doesn't seem to be on any formulary I've checked and is NOT even listed anymore in the PDR. Also, if indeed it has been removed from the market, does anyone know--anecdotally--the reason for it's discontinuation?

Thanks for your time.
