Abstract: This invention relates to imidazolylphenyl amidines, the preparation thereof, and pharmaceutical compositions containing them. More particularly, this invention relates to compounds of the general formula ##STR1## in which R, R.sub.1, and R.sub.3, which may be the same or different, each represent a hydrogen atom or a lower alkyl group, and R.sub.2 represents a linear or branched alkyl, alkenyl, or alkynyl group, a cyano group, a hydroxyl group, a substituted or unsubstituted cycloalkyl or cycloaliphatic alkyl group, a bicyclic group, an aralkyl or aryl group optionally substituted by halogen, methyl, methoxy, or methylenedioxy groups, or a substituted or unsubstituted heterocyclylalkyl or heterocyclic group which may also contain a further hetero atom, or a non-toxic, pharmacologically acceptable acid addition salt thereof. These compounds are useful in treating disorders of the gastrointestinal tract.
