The five antihistaminics: Antergan, Antistine, Benadryl, Neoantergan and Pyribenzamine were effective in non-toxic doses in preventing a histamine-induced spasm of the ileum in dogs with Thiry-Vella Loops. Since the drugs proved additive in their actions, it is presumed that they act by the same or very similar mechanisms.
