This invention discloses the application of lomestatide and its compositions in the preparation of drugs for treating liver fibrosis. The Jin Zhengjun Q-value method is a classic synergistic discriminant model. Cell experiments based on this model show that lomestatide and obeticholic acid exhibit significant synergistic anti-liver fibrosis effects in a molar ratio of 1:2.5 to 1:10, achieving a synergistic effect greater than the sum of its parts (1+1>2). Therefore, compositions of lomestatide and obeticholic acid in a molar ratio of 1:2.5 to 1:10 show promise for development into drugs for treating liver fibrosis. Furthermore, prior art has not disclosed any therapeutic effect of lomestatide on liver fibrosis; therefore, lomestatide also shows promise for development into a drug for treating liver fibrosis.
