Oxyphenisatine

Oxyphenisatine (or oxyphenisatin acetate) is a laxative. It is closely related to Bisacodyl (Brand name: Dulcolax), Sodium Picosulfate, and Phenolthalein. It has been suggested that it is the laxative component in prunes. Long term use is associated with liver damage, and as a result, it was banned by the United States Food and Drug Administration in the early 1970's. Most of the rest of the world follows the FDA lead, so it is no longer available in most of the world.
