Abstract: The use of an anti-MS quinoline-3-carboxamide compound comprising the structure of formula (I), optionally with substituents for the H.sup.1-9 hydrogen, or a salt of said compound where (a) ------------- represents that there are two conjugated double bonds between atoms comprised by the dashed line (only formula I), (b) the hydrogens H.sup.7 and H.sup.8 are attached to different atoms selected from X.sub.1, X.sub.2 and the nitrogen atom in the quinoline ring, (c) X.sub.1 and X.sub.2 are independently selected from an oxygen atom or an NH.sup.9 group, said X.sub.1 and X.sub.2 being bound by a single bond to the ring when carrying H.sub.7 or H.sub.8 and by a double bond when not carrying H.sup.7 or H.sup.8, for the manufacture of a composition intended for the treatment of conditions associated with MS. Also described are treatment regimens for MS patients. The particularly preferred compound is roquinimex or a salt thereof.
