[The preliminary application of vonoprazan fumarate on laryngopharyngeal reflux disease].

Objective: To evaluate the clinical effect of vonoprazan fumarate on laryngopharyngeal reflux disease (LPRD). Methods: The clinical data of 89 patients from June 2020 to January 2022, including 45 males and 44 females, aged 18-77 (45.54±13.53) years old, were retrospectively analyzed. All the patients were diagnosed as suspected LPRD according to reflux symptom index (RSI) and reflux finding score (RFS). Patients of the Vonoprazan Fumarate group were prescribed Vonoprazan Fumarate orally (20 mg, qd) for 8 weeks.Patients of the Esomeprazole group were prescribed Esomeprazole orally (20 mg, bid) for 8 weeks. RSI and RFS of all the patients before and after treatment were compared. SPSS 18.0 was used for statistics analysis. Results: Before treatment, gender, age, RSI and RFS of the two groups had no obvious differences. After treatment, RSI and RFS in both groups were alleviated significantly. In the vonorazan fumarate group, the RSI before treatment was 12.62±7.18, and after treatment was 4.74±3.87( t =6.91, P <0.001), the RFS was 10.78±2.29 before treatment and 8.24±2.45 after treatment ( t =7.06, P <0.001). While in the esomeprazole group, the RSI was 13.27±6.95 before treatment and 6.02±4.28 after treatment ( t =7.50, P <0.001), the RFS was 10.59±3.14 before treatment and 8.14±3.30 after treatment ( t =5.41, P <0.001). There was no significant difference in the effective rate between the two groups (86.7% in the vonoprazan fumarate group and 77.3% in the esomeprazole group, χ ² =1.443, P =0.486). Conclusion: Vonoprazan fumarate could effectively alleviate the symptoms and signs of LPRD patients. The effect of vonoprazan fumarate on LPRD is not inferior to Esomeprazole. It can be used as a supplement to PPI.
