Certain benzodipyrones, e.g., 4,10-dioxo-2,8-dicarboxy-5methoxy-4H,10H-benzo(1,2-b:3,4-b'') dipyran disodium salt and many others which are disclosed, inhibit the release and/or action of toxic products which arise from the combination of certain types of antibody and specific antigen; and are useful in the treatment of conditions - such as asthma, hay fever, etc. - in which antigen reactions are responsible for said conditions. |
