<UnorderedLists id="ula01" listStyle="none"><ListItem>R represents a 5 or 6 membered heterocyclic ring selected among pyridine, pyrimidine, pyrazine, pyridazine, thiophene, furan, thiazole which optionally may be substituted with one or more groups selected among alkyl, alkoxy, halogen, amide, hydroxy, methylthio, trifluoromethyl, cyano, carboxy and the corresponding alkyl esters and salts with alkali metals;</ListItem><ListItem>n is an integer such as 2 or 3;</ListItem><ListItem>X and X' represent each a hydrogen atom or hydroxy group with the exception of both being hydrogen atom, and X' may be also a substituted hydroxy group;</ListItem><ListItem>m is 0 or 1,</ListItem></UnorderedLists>and the corresponding non-toxic pharmaceutically acceptable acid addition salts. The compounds of the formula I are endowed with an interesting antitussive activity and, at their active dose, practically they are free of undesired side effects.
