Abstract
The invention provides amide derivatives of the general formula (I) ##STR1## wherein R.sup.1 is a hydrogen atom or a C.sub.1-6 alkyl group; Y represents a group --(CH.sub.2).sub.m --, where m represents 2, 3 or 4 or a group --X(CH.sub.2).sub.p, where p represents 2 or 3, X represents an oxygen or a sulphur atom or a group NR.sup.5, where R.sup.5 is a C.sub.1-6 alkyl group, and X is attached to the benzene ring moiety of the molecule; and Im represents an imidazolyl group of the formula: ##STR2## wherein one of the groups represented by R.sup.2, R.sup.3 and R.sup.4 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, C.sub.3-6 alkenyl, phenyl or phenylC.sub.1-3 alkyl group, and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C.sub.1-6 alkyl group; and physiologically acceptable salts and solvates thereof. The compounds of formula (I) are potent and selective antagonists of 5-hydroxytryptamine at 5-HT.sub.3 receptors and are useful, for example, in the treatment of psychotic disorders, anxiety and nausea and vomiting.
