Effects of ranitidine and pantoprazole on ventilator-associated pneumonia: a randomized double-blind clinical trial.

Background: Acid suppressive medications are used to prevent stress ulcers in critically ill patients. Few studies have been done to evaluate the effect of ranitidine and pantoprazole on stress ulcers. We aimed to compare the effects of ranitidine and pantoprazole on Ventilator Associated Pneumonia (VAP).
