The effects of pentoxifylline on oxygenation, diffusion of carbon monoxide, and exercise tolerance in patients with COPD.


Pentoxifylline has been reported previously in an unblinded study to improve oxygen saturation, treadmill walk time, and resting diffusion of carbon monoxide (Dco) in patients with COPD. We recruited 12 patients with moderate to severe COPD whose exercise capacity was limited by ventilation or who developed hypoxemia with exercise. Patients were randomized… (More)
