Effectiveness of Additional Administration of a <italic>Banha-sasim-tang</italic> Formulation to Patients with Gastrointestinal Symptoms (KCD K-code) Not Improved by Western Medicines: A Retrospective Chart Review

Abstract

Objectives: The aim of this study was to evaluate the effectiveness of additional administration of Banha-sasim-tang formulation to patients with gastrointestinal symptoms that did not improve with Western medicines.Methods: The patients who met the inclusion and exclusion criteria were analyzed retrospectively. A paired t-test was performed on the Nepean Dyspepsia Index-Korean version (NDI-K) scores before and after administering the Banha-sasim-tang formulation.Results: A total of 27 subjects were included. The mean duration of taking the Banha-sasim-tang formulation was 15.6±3.1 days. The most commonly used Western medicine before taking the Banha-sasim-tang formulation was rebamipide. The means of the NDI-K score were 57.4±21.8 before administering Banha-sasim-tang formulation and 34.9±16.5 after administration, and the difference was statistically significant (p&lt;0.0001). No serious side effects were encountered while taking the Banha-sasim-tang formulation.Conclusions: For patients whose gastrointestinal symptoms do not improve with Western medicines, additional administration of Banha-sasim-tang formulation may be an option. However, as this study is a retrospective chart review, prospective, large-scale, double-blind studies are needed in the future.
