A compound of formula (I) or a pharmaceutically acceptable salt thereof:
in which X represents a group
in which p represents an integer of 2 to 4; r represents an integer of 1 or 2; s represents 0 or 1; and A represents a 3-membered divalent residue completing a 5-membered aromatic ring and comprises one or two heteroatoms selected from oxygen, nitrogen and sulphur, any amino nitrogen optionally substituted by a C 1-4 alkyl group, and when (p,r,s) is (2,2,0) or (2,2,1) any A comprising 2 heteroatoms is optionally C-substituted by a methyl group, and when (p,r,s) is (2,1,0), (2,1,1) or (3,1,0) any A comprising 2 heteroatoms is optionally C-substituted by C 1-2 alkyl and any A comprising one heteroatom is optionally C-substituted by a methyl group, and wherein compounds of formula (I) having two assymetric centres have the stereo-chemical configuration in which the group X and the (CH₂) r bridge are on the same side of the plane of the molecule which contains both bridgehead atoms and the ring carbon atom bonded to the group X.
