The invention relates to tricyclic heterocycles, or pharmaceutically-acceptable salts thereof, which possess anti-hyperalgesic properties. The invention also relates to processes for the manufacture of said tricyclic heterocycles; and to novel pharmaceutical compositions containing them. The invention provides a tricyclic heterocycle of the formula I ##STR1## wherein X is oxy, thio, sulphinyl, sulphonyl, amino, (1-4C)alkylamino or methylene; Y is carbonyl or methylene; each R.sup.1 includes hydrogen and halogeno; each of m and n is 1 or 2; each of A.sup.1 and A.sup.2 is a direct link, alkylene, alkenylene or alkynylene; Ar is phenylene which may optionally bear one or two substituents; and G is carboxy, 1H-tetrazol-5-yl or a group of the formula: --CONH--SO.sub.2 R.sup.2 wherein R.sup.2 is (1-4C)alkyl, benzyl or phenyl; or a pharmaceutically-acceptable salt thereof.
