Carboxamides

Abstract

The invention relates especially to pharmaceutical preparations containing N-(piperidinyl-alkyl)-carboxamides of the general formula ##STR1## in which R represents hydroxy, hydroxy etherified by an aliphatic alcohol, or halogen, Ar.sub.1 represents a monocyclic arylene or heteroarylene radical, alk represents an alkylene group that separates the two N atoms by at least two carbon atoms, X represents a free or ketalized carbonyl group, free hydroxymethylene or hydroxymethylene esterified by an organic carboxylic acid, or methylene, and Ar.sub.2 represents a monocyclic aryl or heteroaryl radical, and salts thereof, the use of these compounds of the formula I and salts thereof, novel compounds of the formula I and salts thereof in which R, Ar.sub.1, alk, X and Ar.sub.2 have the meanings given, with the proviso that the grouping R--Ar.sub.1 is other than a radical of the formula ##STR2## in which R.sub.1 is selected from the group consisting of lower alkyl, trifluoromethyl, halogen, lower alkoxy, nitro and cyano and at least one of the radicals R.sub.1 represents halogen or lower alkoxy, n represents an integer from 1 to 3, and Z represents nitro, amino, lower alkylamino, arylamino, aryl-lower alkylamino, (thio-)formylamino, (thio-)lower alkanoylamino, (thio-)aroylamino or aryl-(thio-)lower alkanoylamino, if alk and X have the meanings given and Ar.sub.2 represents unsubstituted phenyl, thienyl or pyridyl or substituted phenyl having one, two or three substituents selected from the group consisting of halogen, lower alkyl, lower alkoxy, trifluoromethyl and amino, and to processes for the manufacture thereof.
