The invention relates to indole derivatives of the general formula (I) ##STR1## wherein Im represents an imidazolyl group of the formula: ##STR2## and R.sup.1 represents a hydrogen atom or a group selected from C.sub.1-6 alkyl, C.sub.3-6 alkenyl, C.sub.3-10 alkynyl, C.sub.3-7 cycloalkyl, C.sub.3-7 cycloalkylC.sub.1-4 alkyl, phenyl or phenylC.sub.1-3 alkyl; R.sup.2 represents a hydrogen atom or a group selected from C.sub.1-6 alkyl, C.sub.3-6 alkenyl, C.sub.3-7 cycloalkyl, phenyl or phenylC.sub.1-3 alkyl; X represents an oxygen atom or the group NR.sup.3 (where R.sup.3 represents a hydrogen atom or a C.sub.1-6 alkyl group); one of the groups represented by R.sup.4, R.sup.5 and R.sup.6 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; Q represents a hydrogen or a halogen atom, or a hydroxy, C.sub.1-4 alkoxy, phenylC.sub.1-3 alkoxy or C.sub.1-6 alkyl group or a group -NR.sup.7 R.sup.8 or -CONR.sup.7 R.sup.8 (wherein R.sup.7 and R.sup.8, which may be the same or different, each represents a hydrogen atom or a C.sub.1-4 alkyl or C.sub.3-4 alkenyl group, or together with the nitrogen atom to which they are attached form a saturated 5 to 7 membered ring); and physiologically acceptable salts and solvates thereof. The compounds are potent and selective antagonists of the effect of 5-HT at 5-HT.sub.3 receptors and are useful, for example, in the treatment of psychotic disorders, anxiety, and nausea and vomiting.
