The present invention relates to compounds of formula (I): ##STR1## wherein m is zero, 1 or 2; and n is zero or 1, with the proviso that the sum total of m+n is 1 or 2; R.sup.1 represents phenyl; naphthyl; benzhydryl; or benzyl, where the naphthyl group or any phenyl moiety may be substituted; R.sup.2 represents hydrogen; phenyl; heteroaryl selected from indazolyl, thienyl, furanyl, pyridyl, thiazolyl, tetrazolyl and quinolinyl; naphthyl; benzhydryl; or benzyl; wherein each heteroaryl, the naphthyl group and any phenyl moiety may be substituted; R.sup.3 and R.sup.4 each independently represents hydrogen or C.sub.1-6 alkyl or R.sup.3 and R.sup.4 together are linked so as to form a C.sub.1-3 alkylene chain; Q represents CR.sup.5 R.sup.6 or NR.sup.5 ; X and Y each independently represents hydrogen, or together form a group .dbd.O; and Z represents a bond, O, S, SO, SO.sub.2, NR.sup.c or --(CR.sup.c R.sup.d)--, where R.sup.c and R.sup.d each independently represent hydrogen or C.sub.1-6 alkyl; or a pharmaceutically acceptable salt thereof. The compounds are of particular use in the treatment or prevention of pain, inflammation, migraine, emesis and postherpetic neuralgia.
