Reflux esophagitis is a common clinical disease ; pPI or potassium competitive acid blocker ( P-CAB ) is the first choice for the treatment of reflux esophagitis. However, patients with recurrent symptoms and severe esophagitis ( Los Angeles grade C and D ) after long-term use of PPI or P-CAB usually need long-term maintenance treatment. Attention should be paid to the possible adverse reactions of long-term acid suppression therapy and the interaction between drugs. The main efficacy of Jinghua Weikang capsules is regulating qi and dispersing cold, clearing heat and removing blood stasis. Applicable to cold and heat syndrome, qi stagnation and blood stasis caused by epigastric distension, pain, belching, acid reflux, noisy, bitter taste ; duodenal ulcer see the above syndrome. In the early stage, a series of studies were carried out on Jinghua Weikang Capsule, which confirmed that Jinghua Weikang Capsule showed the effect of acid inhibition and symptom relief in the treatment of reflux esophagitis, and had a synergistic effect when combined with western medicine. However, Jinghua Weikang Capsule still lacks sufficient evidence to support the reduction of the recurrence rate of reflux esophagitis. Therefore, we carried out this experiment to explore the clinical efficacy of Jinghua Weikang Capsule in the maintenance treatment of reflux esophagitis, so as to reduce the recurrence rate of reflux esophagitis and relieve symptoms.
