Provided are compositions and methods for treating
lung or respiratory disorders or conditions characterized by
airflow obstruction or limitation, or a symptom thereof (e.g.,
asthma, rhinitis, allergic rhinitis, 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 altered fluid (gas-enriched (e.g.,
oxygen-enriched) electrokinetic fluids) comprising an ionic
aqueous solution of charge-stabilized
oxygen-containing nanostructures as disclosed herein. In certain aspects, the methods comprise regulating
intracellular signal transduction by modulation of at least one of cellular membranes,
membrane potential and / or conductance, membrane proteins (e.g., membrane receptors, (e.g., to
G protein coupled receptors, and intercellular junctions)). Additional aspects include therapeutic compositions, and combination therapies comprising administration of the electrokinetically generated fluids with at least one additional therapeutic agent.
