title: Pantoprazole on-demand effectively treats symptoms in patients with gastro-oesophageal reflux disease.
abstract: OBJECTIVE
  The efficacy of pantoprazole as on-demand therapy for the long-term management of patients with mild gastro-oesophageal reflux disease (GORD) has been demonstrated in clinical studies. In this study, the efficacy of pantoprazole 20mg and esomeprazole 20mg as on-demand therapy for relief of symptoms of mild GORD was compared.
  
  
  METHODS
  Patients with reflux oesophagitis grade A or B (Los Angeles classification) or endoscopy-negative reflux disease (enGORD) were treated with pantoprazole 20mg once daily for 28 days during the acute phase (AP, n = 236). Patients without heartburn during the final 3 days of the AP entered the long-term phase (LTP, n = 199) and were randomised to either pantoprazole 20mg or esomeprazole 20mg as on-demand treatment for 6 months. Antacids were provided as rescue medication during this phase. The mean intensities of the symptoms of heartburn, acid eructation and pain on swallowing, both separately and as a combined symptom score, together with the mean duration of these symptoms during on-demand treatment, were compared between the two treatment groups. The number of tablets taken was also compared.
  
  
  RESULTS
  After 4 weeks of treatment with pantoprazole, 87.3% of patients had relief from heartburn, 74.1% from epigastric pain and 80.8% from acid eructation, according to the investigator assessment. A total of 236 patients were eligible for the on-demand phase. Based on patient diary data, on-demand treatment with pantoprazole resulted in significantly lower mean intensity of heartburn compared with that in the esomeprazole group (1.12 for pantoprazole and 1.32 for esomeprazole, respectively [p = 0.012], in the intention-to-treat [ITT] population). The mean symptom intensities of acid eructation and pain on swallowing, together with the duration of these symptoms, were comparable in the two treatment groups. The combined symptom score of the three symptoms heartburn, acid eructation and pain on swallowing was numerically lower in the pantoprazole group compared with the esomeprazole group (1.72 vs 1.99, respectively, in the ITT population). Tablet intake was comparable in both groups. Relief of symptoms in Helicobacter pylori-positive and -negative patients was also similar in both treatment groups. Both treatments were well tolerated with a good safety profile.
  
  
  CONCLUSIONS
  On-demand therapy with either pantoprazole 20mg or esomeprazole 20mg is a comparably effective treatment strategy for the long-term treatment of non-erosive and mild GORD. However, the mean intensity of heartburn was significantly lower with pantoprazole treatment.
