The present invention provides substituted dibenzoxazepine compounds of Formula I: ##STR1## which are useful as analgesic agents for the treatment of pain, pharmaceutical compositions comprising a therapeutically-effective amount of a compound of Formula I in combination with a pharmaceutically-acceptable carrier, and a method for eliminating or ameliorating pain in an animal comprising administering a therapeutically-effective amount of a compound of Formula I to the animal.
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
wherein X is oxy, thio, sulphinyl, sulphonyl, amino, (1-4C)alkylamino or methylene;
Y is carbonyl or methylene;
each R¹ includes hydrogen and halogeno;
each of m and n is 1 or 2;
each of A¹ and A² 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-SO₂R²
wherein R² is (1-4C)alkyl, benzyl or phenyl;
or a pharmaceutically-acceptable salt thereof.
