There is disclosed a pharmaceutical composition for providing antiinflammatory, antipyretic, analgesic, antiallergic, immunosuppressing or immunomodulating activity which comprises a pyridine derivative of the formula (I):
wherein R is an optionally substituted pyridine ring, X is a oxygen atom or -S(O)n-, wherein n is 0, 1 or 2, A is a bivalent C₁₋₁₅ hydrocarbon residue whose branched moiety may have a substituent, Y is an oxygen or sulfur atom, R₃ is a hydrogen atom or an optionally substituted hydrocarbon residue, R₄ is an optionally substituted hydrocarbon residue or an optionally substituted monocyclic or bicyclic heterocyclic group, R₃ and R₄ may be joined together with the carbamoyl group or the thiocarbamoyl group to which they are attached to form an optionally substituted heterocyclic group, or R₃ or R₄ may be independently attached to A to form a ring, or a pharmaceutically acceptable salt or solvate thereof, and a pharmaceutically acceptable carrier or diluent.
