Abstract: The present invention is directed to compounds of the formula (I): ##STR1## (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.9a, R.sup.9b, m and n are as defined herein) which are tachykinin antagonists and which are particularly useful in the treatment of pain, inflammation, migraine, emesis and postherpetic neuralgia.

Abstract: The present invention relates to compounds of formula (I) and salts and prodrugs thereof, wherein Q.sup.1 represents a phenyl group substituted by one or more halo optionally substituted naphthyl, optionally substituted indolyl, optionally substituted benzthiophenyl, optionally substituted benzofuranyl, optionally substituted benzyl or optionally substituted fluorenyl; R.sup.1 represents H or C.sub.1-6 alkyl; R.sup.2 represents H, C.sub.1-6 alkyl or C.sub.2-6 alkenyl; Z.sup.1 represents a group selected from (a) or (b). The compounds are tachykinin antagonists useful for treating pain or inflammation, migraine or emesis.
