Provided are compositions and methods for treating or preventing lung or respiratory disorders or conditions characterized by airflow obstruction or limitation, or a symptom thereof (e.g., asthma, rhinitis, allergic rhinitis (e.g. nose respiratory tract), and chronic obstructive pulmonary disease (COPD) and COPD-associated conditions (e.g., bronchitis, emphysema, asthma), emphysema, pneumonia, bronchitis, influenza, SARS, tuberculosis, and whooping cough (pertussis), and the like) in a subject in need thereof by administering a therapeutic composition comprising at least one electrokinetically generated fluid (including gas-enriched electrokinetically generated fluids) as disclosed herein, the electrokinetically altered aqueous fluid suitable to alter cellular membrane structure or function sufficient to provide for modulation of intracellular signal transduction, wherein treating a lung disorder or a symptom thereof is thereby afforded. Additional aspects relate to therapeutic compositions, and combination treatment methods comprising administration of at least one electrokinetically generated fluid in combination with at least one additional therapeutic agent.
