Possibly, although it would have absolutely no prokinetic effects on making the gut move again. The primary problem in "stasis" is that the gut is static and not moving, the prokinetic actions of metaclopramide, Zantac and Cisapride (and I am sure there are others...) are what kick start the gut into moving again. It may reduce nausea if the rabbit was feeling nauseus (are they capable of nausea??) but would not help the gut to move. My vet is an exotic specialist and had never heard of it being used, but thats not to say that it hasn't. She has recently taken her certificate exam though so is pretty up to date with things.
I would definitely speak to the vet about it. It would be interesting to hear what he/she says about it. If it is indeed a useful drug for bunnies then it would be good to know, also where they got the info from so I can point my vet in the direction so she can have a read too.
