Pilot Study of On-Demand Therapy with Pantoprazole 20mg for Long-Term Treatment in Patients with??Mild Gastro-Oesophageal Reflux Disease

Approaches to Deprescribing Proton Pump Inhibitors in Clinical Practice: A Systematic Review

Background: Proton pump inhibitors (PPIs) are some of the most frequently prescribed medications, but they are often used inappropriately, either being prescribed without a clear indication or continued for longer than necessary. In such cases, deprescribing is recommended. However, despite its proven effectiveness, the implementation of deprescribing in clinical practice remains inconsistent and varied, making it challenging to identify the most effective strategies. The goal is to provide a comprehensive outline of deprescribing interventions for PPI therapy implemented across various settings and by different healthcare professionals. Methods: The study is designed to be a systematic review of the published literature. PubMed, Embase, and Web of Science databases were searched from 1 January 1989 (the first PPI on the market) to 30 September 2024 for articles assessing PPI deprescribing in adult patients, focusing on the implementation rate (primary outcome) or effects on symptoms (secondary outcome). Results: After screening, 66 studies were included, predominantly pragmatic trials (N = 32) or randomized controlled trials (N = 25). We found a variety of interventions promoting PPI deprescription. Collaborative efforts involving multiple healthcare professionals, the use of algorithms for clinical decision-making, and patient involvement have proven to be key elements in the most effective strategies. Discontinuing therapy may not be advisable in cases of recurrent symptoms, suggesting that on-demand therapy could be a recommended approach. Deprescribing is particularly relevant for individuals with mild illnesses and symptoms, where tapering can effectively mitigate the rebound symptoms often associated with abrupt discontinuation. Conclusions: Given the current prevalence of inappropriate PPI prescribing, it is imperative to raise awareness among both physicians and patients about the importance of the deprescribing process, which should be tailored to the specific needs of each patient, considering his/her medical history, current health status, and personal preferences.

Pantoprazole on-demand effectively treats symptoms in patients with gastro-oesophageal reflux disease

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.

CONCLUSION

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.
