It can be treated with procaine solution and nitroglycerin tablets. The main function of the cardia is to prevent reflux of food in the stomach. The main function of the cardia is to prevent the reflux of food from the stomach. When the cardia is dysflaccid, the stomach acid will pass through the cardia more easily and cause damage to the esophageal mucosa, triggering the onset of esophagitis. Procaine solution is a local anesthetic that can help improve the symptoms of cardia and reduce the likelihood of acid reflux. Nitroglycerin tablets are mainly used for the treatment of angina pectoris and can be considered for sublingual administration when cardia is present due to the drug’s effect of relaxing smooth muscle. Patients with severe cardia flaccid symptoms and ineffective medication can consider surgical treatment with endoscopic placement of a relaxing dilator.
