From the standpoint of evidence - based medicine, the ability of various drugs to induce the development of gastroesophageal reflux disease and esophagitis is considered. Thus, all known drugs can be divided into 3 groups: drugs that have the ability to reduce pressure in the lower esophageal sphincter, for example, β-adrenoreceptor agonists, α-adrenoreceptor antagonists, anticholinergics, calcium channel blockers, nitrates, benzodiazepines (diazepam), estrogen, progesterone, aminophylline (theophylline), tricyclic antidepressants, selective serotonin reuptake inhibitors, glucocorticosteroids; means providing a direct damaging effect on the esophageal mucosa, as well as lowering its resistance reflyuktatu, e.g., bisphosphonates, acetylsalicylic acid / non - steroidal anti - inflammatory agents, anticoagulants, antiplatelet drugs, iron preparations, ascorbic acid, potassium chloride, quinidine, phenytoin, calcium dobesilate, 131I sodium iodide, antibiotics (tetracycline, doxycycline, clindamycin, ciprofloxacin, ornidazole, clindamycin, rifampicin), antitumor agents; drugs that impede gastric emptying: calcium channel blockers, anticholinergics. These data can be used in practice in the choice of treatment tactics, especially in individuals with a diagnosis of gastroesophageal reflux disease or heartburn.
