The invention relates to medicine, and aimed at the creation of pharmaceutical aerosols with active substances of protein nature and propellant ejection systems for the treatment of a wide range of human diseases. Invention describes a quantitative ratio of the components and their mixing procedure for the preparation of an aerosol composition allowing generating the aerosol of an active protein substance from the group of protease inhibitors. The developed pharmaceutical aerosol formulation of protease inhibitors will be widely used in medicine, since the disturbance of proteolytic balance, requiring correction with protease inhibitors, develops in many human and animal diseases, such as respiratory infections, including influenza, herpetic lesions of skin and mucous membranes, chronic obstructive bronchial pneumonia, asthma and others.
