Abstract: The present invention relates to pharmaceutical formulations for treating a respiratory tract infection or a pulmonary disease in an individual, comprising a calcium salt and a sodium salt, wherein the ratio of Ca+2 to Na+ is from about 4:1 (mole:mole) to about 16:1 (mole:mole). The invention also relates to methods of treating (including prophylactically treating) and reducing the spread of a respiratory tract infection, methods of treating (including prophylactically treating) a pulmonary disease or an acute exacerbation of a pulmonary disease, and methods of reducing the spread of an acute exacerbation of a pulmonary disease, comprising administering a pharmaceutical formulation that comprises a calcium salt and a sodium salt.

Abstract: The invention relates to pharmaceutical compositions that contain a calcium salt as an active ingredient and also comprise another anti-influenza agent, and to methods for treating or preventing influenza virus infection.

Abstract: The present invention is directed toward respirable dry particles for delivery of divalent metal cation salts and/or monovalent cation salts to the respiratory tract and methods for treating a subject having a respiratory disease and/or infection.

Abstract: The invention relates to methods for treating bacterial infection of the respiratory tract, including pneumonias, such as ventilator-associated pneumonia, and to methods for treating ventilator-associated tracheobronchitis, comprising administering an effective amount of a salt formulation as an aerosol to the respiratory tract of an individual in need thereof. The formulations can also be used to reduce transmission of pathogen which can infect the respiratory tract, cause pneumonia or cause ventilator-associated tracheobronchitis.
