Oxyphenisatine (or oxyphenisatin) is a laxative. It is closely related to bisacodyl, sodium picosulfate, and phenolphthalein. Long term use is associated with liver damage, and as a result, it was withdrawn in most countries in the early 1970s. The acetate derivative oxyphenisatine acetate was also once used as a laxative.
