Abstract

The present application relates to the use of fused heteroaromatic pyrrolidones for treatment and/or prophylaxis of allergic and/or inflammatory diseases in animals and to the use thereof for production of medicaments for treatment and/or prophylaxis of allergic and/or inflammatory diseases in animals, especially of atopic dermatitis and/or Flea Allergy Dermatitis, and especially in domestic animals, particularly in dogs.
