Esomeprazole relieves upper gastrointestinal symptoms in high-risk and average-risk NSAID users in daily clinical practice: results from an open-label study

Gastrointestinal symptoms in NSAID users in an 'average risk population': results of a large population-based study in randomly selected Dutch inhabitants

AIM

Non-steroidal anti-inflammatory drug (NSAID) use is widespread and associated with gastrointestinal symptoms and complications. The aims of this study were to assess (i) gastrointestinal symptoms in users of prescribed and over-the-counter (OTC) NSAIDs and (ii) proton pump inhibitor (PPI) co-prescription rates in NSAID users at increased risk for gastrointestinal complications.

METHODS

Surveys were sent to a randomly selected sample of the adult Dutch general population in December 2008. Questions included demographics, gastrointestinal symptoms, medication use and comorbidity. Main outcome measure was presence of gastrointestinal symptoms.

RESULTS

A total of 18,317 surveys were returned (response rate 35%), of which 16,758 surveys were eligible for analysis. Of these, 3233 participants (19%) reported NSAID use. NSAID users more frequently reported gastrointestinal symptoms than persons not using NSAIDs (33% vs. 24%, p < 0.01). Respondents who specified on prescription NSAID use (n = 683) were older, reported more comorbidity, and experienced more gastrointestinal symptoms (41%) compared with OTC users (n = 894, 33%, p < 0.01). This difference was not statistically significant after adjustment for confounders (0.99, 95% CI 0.71-1.37). In respondents with an increased gastrointestinal risk profile, PPI co-prescription rates were 51% for on prescription users and 25% for OTC users.

CONCLUSIONS

Prevalence of gastrointestinal symptoms was high in both prescribed and OTC NSAID users, emphasising the side effects of both types of NSAIDs. PPI co-prescription rates in NSAID users at risk for gastrointestinal complication were low.
