First Trial to Confirm Nexium (Esomeprazole) Provides Relief for Non-GERD Dyspeptic Patients The study provided evidence that a substantial proportion of this difficult-to-treat patient group will benefit from acid-suppression therapy MONTRÉAL, CANADA -- September 21, 2005 -- Results from a new study show that treatment with Nexium(R) (esomeprazole) is effective for relieving upper-abdominal symptoms in patients with non-gastroesophageal reflux disease (non-GERD) dyspepsia. These findings, being presented today at the World Congress of Gastroenterology (WCOG), are from the first trial of its kind, conducted to investigate the effect of proton pump inhibitor (PPI) therapy on patients with non-GERD dyspepsia, a notoriously difficult to treat group of patients.1 The trial, involving uninvestigated (no endoscopy performed) patients, found that at both 4 and 8 weeks, Nexium provided a significantly higher overall response rate than placebo (P <.001). 47.3% of patients responded at eight weeks of treatment with Nexium 40mg qd, compared to 33.7% on placebo (following the initial week of 40mg Nexium qd). Professor Sander Van Zanten, Dalhousie University, Canada said that the results of the study provide convincing evidence that a substantial proportion of non-GERD dyspepsia patients will respond to acid suppression therapy with Nexium(R). "Many primary care patients who present with upper-abdominal symptoms such as epigastric pain or burning are not referred for further investigation and there has been much uncertainty whether they will respond to treatment with a proton pump inhibitor. These results support the use of Nexium for managing patients with dyspepsia and provide physicians with the evidence for treating this difficult to treat patient population." Dyspepsia is a very common complaint, occupying about four% of all primary care consultations.2,3 It also represents a considerable economic burden, with one study estimating that dyspepsia may be costing society £1 billion each year in the UK.4 The data also show that 62.7% of uninvestigated non-GERD dyspepsia patients who had a positive response to a one-week AST of Nexium 40 mg qd (defined as no more than mild symptoms at the end of the 7 day treatment) experienced complete symptom resolution after a further seven weeks of Nexium 40 mg, compared to 47.2% on placebo (P <.05). This suggests that a one-week acid suppression trial will help to predict whether patients will respond after eight weeks. However a certain proportion of non-responders at one week will respond by eight weeks, indicating that it is worthwhile to give these patients a treatment trial for up to eight weeks. Information about Nexium Nexium works by deactivating the proton (acid) pumps that produce stomach acid, thus reducing the amount of acid that is in the stomach, helping to treat heartburn and other symptoms of GERD. Several comparative clinical trials with more than 15,000 patients with Nexium, including the EXPO, the EAZEE and Metropol studies, confirm that Nexium provides superior acid control which translates into clinical benefits.5,6,7,8,9,10 Nexium(R) is only available on prescription. The most common side-effects with Nexium are headache, diarrhoea, and abdominal pain, which occur in around one% of patients. REFERENCES: 1. Velhuyzen Van Zanten S et al.
