Method for treating infectious respiratory diseases

A method of treating pneumonia in a human, susceptible to or suffering from pneumonia caused by respiratory syncytial virus or parainfluenza virus type 3, comprising administering directly into the lower respiratory tract of the human an anti-inflammatory agent selected from a corticosteroid, indomethacin, ibuprofen, and acetylsalicylic acid at a dosage of from 0.1 .mu.g to 1000 mg/kg body weight of the host to reduce inflammation and an human immunoglobulin G at a dosage of from 0.1 .mu.g to 100 mg/kg body weight of the host to reduce the concentration of the respiratory syncytial virus or parainfluenza virus type 3, the anti-inflammatory agent and the anti-infectious agent being administered in the form of a small particle aerosol having a size less than 10 microns.

A method of treating pneumonia in a host, susceptible to or suffering from pneumonia caused by parainfluenza virus type 3, adenovirus type 5, or respiratory syncytial virus, comprising administering directly into the lower respiratory tract of the host an anti-inflammatory agent selected from a corticosteroid, indomethacin, ibuprofen, and acetylsalicylic acid at a dosage of from 0.1 .mu.g to 1000 mg/kg body weight of the host to reduce inflammation and an anti-infectious agent with activity against said virus at a dosage of from 0.1 .mu.g to 1000 mg/kg body weight of the host to reduce the concentration of said virus, the anti-inflammatory agent and the anti-infectious agent being administered in the form of a small particle aerosol having a size less than 10 microns.

A medication that comprises aerosol particles having a size of less than 10 microns comprising an anti-infectious agent with activity against an infectious agent at a dosage of from 0.1 .mu.g to 1000 mg/kg body weight of a host to reduce the concentration of said infectious agent and an anti-inflammatory agent selected from a corticosteroid, indomethacin, ibuprofen, and acetylsalicylic acid at a dosage of from 0.1 .mu.g to 1000 mg/kg body weight of the host to reduce inflammation.

A method of treating pneumonia in a host, susceptible to or suffering from pneumonia caused by a microorganism selected from a virus, a bacterium, a fungus, and Pneumocystis carinii, comprising topically administering directly into the lower respiratory tract of the host an anti-inflammatory agent selected from a corticosteroid, indomethacin, ibuprofen, and acetylsalicylic acid at a dosage of from 0.1 82 g to 1000 mg/kg body weight of the host to reduce inflammation and an human immunoglobulin G at a dosage of from 0.1 .mu.g to 100 mg/kg body weight of the host to reduce the concentration of said microorganism, the anti-inflammatory agent and the human immunoglobulin G being administered in the form of a small particle aerosol having a size less than 10 microns.
