potassium-bicarbonate and Gastroesophageal-Reflux

Alternative treatments are commonly used for various disorders and often taken on-demand. On-demand treatment of gastroesophageal reflux disease (GERD) with pharmaceutical products is an established, cost-effective strategy. Comparisons between alternative medicine and pharmaceutical products are rare. The aim of this trial was to compare on-demand treatment with a pectin-based, raft-forming, natural, anti-reflux agent (PRA) with that of esomeprazole 20 mg (Eso20) in patients with mild/moderate GERD.. Patients with mild/moderate GERD were randomised to a six weeks' on-demand treatment with PRA or Eso20 in a pragmatic, open, multicentre trial. Overall satisfaction with treatment, satisfactory relief on a weekly basis, reflux symptoms, and treatment preferences were noted.. Seventy-seven patients were included in the analyses. Eso20 was significantly superior to PRA for proportion of overall satisfied patients (92% and 58% respectively; p = 0.001), reduction of symptoms (mean symptom scores at the end 5.9 and 8.0 respectively; p = 0.019), proportion of weeks of satisfactory relief (89% and 62% respectively; p = 0.008) and proportion preferring continuation with the same treatment (85% and 42% respectively; p < 0.001). Older patients were more satisfied than younger, and patients preferring on-demand treatment had lower symptom scores at inclusion than those preferring regular treatment.. On-demand treatment with esomeprazole 20 mg was clearly superior to the pectin-based raft-forming agent. Most patients preferred on-demand treatment to regular treatment. Those preferring regular therapy had significantly more symptoms at inclusion.

During a reflux event the oesophagus is exposed to a heterogeneous mixture of gastric juice components. The role of non-acid components of the refluxate in causing damage to the oesophagus is now well established but no therapeutic option exists to address this.. The role of Gaviscon Advance (GA), a raft-forming alginate suspension, in protecting the oesophagus from damage by pepsin and bile acids (aggressors) was investigated using a series of in-vitro models.. GA was able to dose-dependently inhibit pepsin activity over and above the neutralisation effect of the formulation. This was evident against both protein and collagen substrates using two distinct colorimetric assays. GA was able to retard the diffusion of pepsin and multiple bile acids using a Franz cell model. Using the raft-forming mode of action GA was able to remove both pepsin and multiple bile acids from a simulated reflux event. There was capacity in the GA raft to accommodate aggressors from multiple reflux events.. GA can specifically remove both pepsin and bile acids from the refluxate, limit their diffusion and affect enzymatic activity of pepsin. There is a role for GA to reduce the damaging potential of the refluxate and thus protect the oesophagus.
