Efficacy of esomeprazole for resolution of symptoms of heartburn and acid regurgitation in continuous users of non-steroidal anti-inflammatory drugs.
BACKGROUND
The use of non-steroidal anti-inflammatory drugs (NSAIDs) is often associated with upper gastrointestinal symptoms such as heartburn and acid regurgitation.


OBJECTIVE
To assess the efficacy of esomeprazole 20 and 40 mg for resolution of heartburn and acid regurgitation in continuous NSAIDs.


METHODS
A post hoc analysis of five clinical trials was performed. Two identically designed, placebo-controlled, 4-week studies (NASA1, SPACE1) enrolled non-ulcer, NSAIDs-treated patients with upper abdominal pain, discomfort or burning. PLUTO and VENUS were identically designed, placebo-controlled, 6-month studies that enrolled patients at risk of NSAIDs-induced ulcers. Study 285 was an 8-week comparative study with ranitidine (300 mg/day) in patients with NSAIDs-induced gastric ulcers. Resolution of investigator-assessed heartburn and acid regurgitation was defined as symptom severity of 'none' in the last 7 days.


RESULTS
In NASA1/SPACE1, heartburn resolved in 61% and 62% of patients taking esomeprazole 20 and 40 mg, respectively (vs. 36% on placebo, P < 0.001), and acid regurgitation resolved in 65% and 67% (vs. 48%, P < 0.001). Resolution of both symptoms was greater with esomeprazole than with placebo in PLUTO/VENUS (P <or= 0.001), and than with ranitidine in study 285 (P < 0.05 for esomeprazole 20 mg).


CONCLUSIONS
Heartburn and regurgitation are common in patients taking NSAIDs and esomeprazole is efficacious for resolution of these symptoms.
