Aim of publication. To present the latest data on adequate diagnostic methods, treatment approaches and features of rational pharmacotherapy of gastroesophageal reflux disease (GERD) based on the principles of evidence­based medicine to general practitioners. Summary. The prevalence of GERD occupies the first place of other gastroenterological diseases. The heartburn that is a leading GERD symptom is present at 20-40% of the population of developed countries. The prevalence of GERD in Russia ranges 18­46%. Diagnosis of GERD early stages is based on the primary appealability and clinical presentation evaluation. Esophagogastroduodenoscopy (EGDS) gives the chance to define the presence of reflux esophagitis, to estimate severity grade, to reveal development of esophageal epithelium columnar metaplasia. At the refractory course (lack of conclusive clinical and endoscopic remission within 4-8 wks of treatment by standard dose of proton pump inhibitor - PPI), and development of complications (strictures, Barret's esophagus) examination within specialized hospital or gastroenterological clinic is required, including their out­patient departments. Under certain indications the patient should undergo EGDS with esophageal biopsy and histological examination of biopsy specimens to rule out the Barret's esophagus, esophageal adenocarcinoma and/or eosinophilic esophagitis; intraesophageal 24­hour pH­metry or pH­impedance measurement; high resolution esophageal manometry; X­ray study of the esophagus and stomach. The treatment of GERD has to be individualized according to the pattern and severity of clinical symptoms. The goal of treatment is symptom relief, at erosive esophagitis - healing of erosions and complication prevention, at Barret's esophagus - prophylaxis of disease progression and dysplasia and adenocarcinoma development. Nowadays PPIs are considered as the most effective and safe agents for GERD treatment. PPIs are applied for the long­term baseline treatment (no less than 4-8 wks) and maintenance therapy (6-12 months). Intake of alginates is pathogenically reasonable therapeutic approach for reduction of «acid pocket» and acid neutralization in the area of gastro­esophageal junction in GERD patients by formation of mechanical barrier raft which prevents reflux of the stomach content into the esophagus. Antacid monotherapy is recommended for the cases of rare heartburn which is not accompanied by esophagitis and in complex modes of GERD treatment for achievement of rapid symptom relief. Adsorbents are applied as monotherapy at non­ erosive reflux disease, and as a component of comprehensive GERD treatment, especially of the cases of mixed (acid + biliary) refluxes. Prokinetic drugs promote recovery of a normal physiological state of the esophagus, controlling the pathogenic mechanisms of GERD, reducing the number of transient lower esophageal sphincter relaxations and improving esophageal clearance due to stimulation of the lower gastrointestinal motor function. Prokinetics can be applied as a component of comprehensive treatment of GERD along with PPI. Anti­reflux surgery is indicated in complicated cases (recurrent bleeding, peptic esophageal strictures, development of Barret's esophagus with high­grade epithelial dysplasia, frequent aspiration pneumonias). Surgical treatment of GERD is more effective in patients was typical manifestations and positive treatment response to PPIs. Conclusion. Implementation of clinical guidelines can promote improvement of healthcare quality for GERD patients and prevent complications, in particular if terms of treatment will be observed, at active outpatient follow­up for certain groups of patients.
