Randomized Controlled Trial Clinical TrialEffect of naproxen on gastroesophageal reflux and esophageal function: a randomized, double-blind, placebo-controlled study.
Gastrointestinal symptoms, particularly pyrosis, complicate nonsteroidal anti-inflammatory drug (NSAID) use. NSAIDs cause esophageal injury, and H2 blockers are often prescribed for, and successfully control, NSAID-related symptoms. To determine whether NSAIDs can induce gastroesophageal reflux, we studied the effect of a commonly used NSAID, naproxen, on reflux parameters and esophageal function. ⋯ Naproxen did not induce reflux in normal subjects, although reflux did increase in some subjects. Naproxen had no significant effect on motility parameters. Our data suggest that NSAIDs do not impair the anti-reflux barrier or induce reflux. Pyrosis experienced during NSAID use may not arise from the esophagus or may reflect altered esophageal sensitivity. A single subject with decreased LESP and asymptomatic increased acid exposure in the basal state had a marked increase in reflux on naproxen. This person subsequently developed symptomatic gastroesophageal reflux. The effect of NSAIDs on individuals with a propensity to reflux deserves further study.
