Psoriasis in mammals is relieved by topically administering naphthalenes of the formula:
wherein:
R' is alkoxy of one to twelve carbon atoms, of one to twelve carbon atoms, alkylthio of one to twelve carbon atoms, optionally substituted phenoxy or optionally substituted phenylthio;
R2 is hydrogen, lower alkyl, optionally substituted phenyl or optionally substituted phenylalkyl;
R3 is lower alkyl, lower alkoxy, or halo and m is 0, 1 or 2, or R3 is optionally substituted phenyl, optionally substituted phenyl lower alkyl, optionally substituted phenyl lower alkoxy, amino, lower alkylamino, lower dialkylamino, cyano, or S(O)nR wherein R is lower alkyl; optionally substituted phenyl; optionally substituted phenyl lower alkyl; or optionally substituted heterocyclic aryl of three to nine ring atoms containing one or two heteroatoms selected from the group consisting of nitrogen, oxygen and sulfur, and the pharmaceutically acceptable acid addition salts thereof; and m is 1 and n is 0, 1 or 2; and
W is alkyl of one to seven carbon atoms, optionally substituted phenyl or optionally substituted benzyl.
