Thioalkanoyl-carnitines of general formula (I) <IMAGE> wherein R is a straight alkylene radical having from 2 to 6 carbon atoms, or is a branched alkylene radical having from 3-6 carbon atoms, or is a branched alkylene radical having from 3-6 carbon atoms, R1 is a straight or branched lower alkyl radical having from 1 to 4 carbon atoms, and X- is a halogen anion are prepared by reacting a thio-acid (II) of general formula R1COSH (a) if in (I) the thioalkanoyl radical R1COS- is in terminal position, with a compound of general formula (III) <IMAGE> wherein n is an integer comprised between 0 and 4 or (b) if in (I) the thioalkanoyl radical R1COS- is not in terminal position, with a compound of general formula (IV) <IMAGE> wherein m and m1 are integers comprised between 0 and 3, and R2 is a lower alkyl radical having from 1 to 4 carbon atoms. The pharmaceutical compositions containing the thioalkanoyl-carnitines (I) possess mucolytic and antitussive activity. |
