(Nexium) is mainly used to treat gastroesophageal reflux disease. Nexium should be swallowed whole with liquid and should not be chewed or crushed once daily for four weeks as a long-term maintenance treatment for patients with cured esophagitis to prevent recurrence. Pay attention when the patient experiences weight loss, repeated vomiting, dysphagia, vomiting blood or black stool. Malignancy needs to be ruled out when gastritis or gastric ulcer is suspected. Patients who use this medicine long-term need to be tested regularly.

In a clinical comparative study between Nexium and omeprazole in the treatment of reflux esophagitis, the total effective rate of Nexium was 97.18%, which was significantly higher than omeprazole's 84.51%, and there was no significant difference in the incidence of adverse reactions. Chen Caiming conducted a cost-effectiveness analysis on the treatment of duodenal ulcers with omeprazole and Nexium. The recovery rate of the esomeprazole group was 92.6%, which was higher than 78.6% for omeprazole. The results proved that esomeprazole has cost and effectiveness advantages. 

Nexium keeps the gastric pH >4 for longer. A study on the duration of gastric pH > 4 and the healing rate of reflux esophagitis showed that the longer the duration of pH > 4 within 24 hours, the greater the number of patients who healed after 8 weeks. After taking different drugs orally for 5 days, the duration of pH>4 in the stomach within 24 hours from longest to shortest is: Nexium 40 mg, omeprazole 40 mg, lansoprazole 30 mg, pantoprazole 40 mg and rabeprazole 20 mg. This shows that Nexium 40mg has a stronger acid-suppressing effect than other proton pump inhibitors. Clinical trials have also fully confirmed the excellent pH control capabilities of Nexium 40mg. In general, Nexium is very effective in treating early gastric cancer.
