Abstract: The present invention relates to the use of the compounds of formula: ##STR1## in which R.sub.1 is a linear, branched or cyclized C.sub.1 -C.sub.5 alkyl radical andR.sub.2 represents a hydrogen atom, a linear or branched C.sub.1 -C.sub.5 alkyl radical, a hydroxyl radical, a C.sub.1 -C.sub.5 alkoxy radicalor a C.sub.1 -C.sub.2 hydroxyalkyl radical, andR.sub.3 represents a hydrogen atomor R.sub.2 and R.sub.3 both represent a C.sub.1 -C.sub.5 alkyl radical,these compounds being 2R in configuration, as well as of the racemates comprising these compounds, and of their pharmaceutically acceptable salts, for the manufacture of a medicament intended for the treatment of pain of visceral origin.

Abstract: Novel N-cyclohexylbenzamide derivatives of formula: ##STR1## where R.sub.1 represents an alkoxy radical capable of cyclizing with the aromatic ring;R.sub.2, R.sub.3 and R.sub.4 each independently represent hydrogen, a halogen or an alkoxy, amino, alkylamino or alkyl-carbonylamino group, andZ represents a differently substituted piperidinyl group; and their addition salts with pharmaceutically acceptable acids.The compounds of formula I are powerful gastrointestinal motility stimulants.
