[Effect of different course of omeprazole in the treatment of laryngopharyngeal reflux].

Objective

To compare the efficacy and safety of omeprazole in the treatment of laryngopharyngeal reflux. Method:One hundred and sixty patients with laryngopharyngeal reflux in our hospital from March 2015 to January 2017 (diagnosis treatment for 8 weeks) were selected and randomly divided into group A, B, C, D, with 40 cases in each group. Each group of patients were treated with omeprazole enteric-coated capsules (20mg, Bid) for 1, 2, 3 and 4 months, respectively. The reflux symptom index(RSI), reflux finding score(RFS) score, and 24h intraesophageal pH-metry , pepsin detection were compared between the four groups before treatment, at the end of treatment, at 1 month and 2 months after treatment. The efficacy and side effects were evaluated.Result:With the increase of treatment course, patient's RSI and RFS score, 24h pH-metry <4.0 percentage, pepsin positive rate decreased gradually, and there was a significant difference between before and after treatment. After treatment, there was a statistical significance in group B and group A, group C and group B. There was no significant difference between group D and group C. After the end of treatment and up to 2 months of follow-up, the RSI and RFS scores gradually increased and 24h Ph-metry <4.0 percentage, pepsin positive rate increased in group A and B,and those were not significantly different in group C and group D. With the increase of treatment duration, the effective rate of treatment increased, which was 67.5%, 80.0%, 90.0% and 95.0%, respectively. The difference was statistically significant, but the adverse effects did not increase (P>0.05).

Conclusion

Omeprazole is safe and effective in the treatment of laryngopharyngeal reflux. The symptoms and signs of the patients are obviously improved during the 5 months of the course, and the condition is relatively stable and the recurrence rate is low.
