Pharmacotherapy of acute respiratory distress syndrome

To date, the only therapeutic option that has convincingly been shown to decrease mortality in acute respiratory distress syndrome (ARDS) has been to use a lung-protective strategy that minimises the iatrogenic consequences of providing adequate life support through the use of mechanical ventilation. In terms of the pharmacological options for ARDS, no single drug or treatment has been shown to be the magic bullet in this disease. The search for novel therapies and pharmacological agents is active and relentless. Important pathophysiological areas of focus are preventative therapy, supportive care and treatment of the underlying inflammatory process. In this paper we will review current and experimental approaches to the management of ARDS. In addition, the pathophysiological basis for their putative modes of action, the current state of the literature and the potential for future clinical development will be discussed.
