HC Deb 18 March 1985 vol 75 c379W
Mr. Dykes

asked the Secretary of State for Social Services if he will list the medicines which currently contain the intense sweetener Aspartame.

Mr. Kenneth Clarke

Information about formulations of individual products is of commercial value and is given to the licensing authority in confidence. There are in fact no medicinal products containing aspartame currently being marketed in the United Kingdom.
