The invention relates to new sulphonamide derivatives of benzo-cyclic or benzo-heterocyclic acids and their derivatives of general formula I ##STR1## in which: R represents a straight-chain or branched lower alkyl radical having 1 to 9 C; a phenyl radical which is unsubstituted or substituted by one or more groups: straight-chain or branched lower alkyl having 1 to 4 C, halogeno, alkoxy, nitro, amino, dialkylamino or CF.sub.3 ; a substituted or unsubstituted naphthalene; a thiophenyl radical; R.sub.1 represents a hydrogen or a straight-chain or branched lower alkyl or a benzyl; R.sub.2 represents a hydrogen, a straight-chain or branched lower alkyl group, a substituted or unsubstituted phenyl group or an aralkyl group; R.sub.3 represents a hydrogen or a straight-chain or branched lower alkyl (1 to 6 C); --X-- represents a divalent functional radical chosen from the following: --CH.sub.2 --; ##STR2## where R.sub.4 =H or Me; A represents a benzo-cyclic or benzo-heterocyclic divalent radical chosen from the following (a) to (j): ##STR3## and n can assume the values 1 to 4 inclusive; and the therapeutically acceptable organic or inorganic salts (R.sub.3 =H), the pure isomers or diastereoisomers or their mixture and all the pharmaceutical compositions of formula I with other active principles. The invention relates to the application of I as a medicament and the preparation processes.
