Treatment with senicapoc in a porcine model of acute respiratory distress syndrome.

In summary, senicapoc failed to improve the primary endpoint PaO2/FiO2 ratio, but reduced pulmonary hemorrhage and the influx of neutrophils into the lung. These findings open the perspective that blocking KCa3.1 channels is a potential treatment to reduce alveolar neutrophil accumulation and improve long-term outcome in ARDS.
