Abstract

The invention relates to application of combination of an angiotensin converting enzyme inhibitor and an angiotensin receptor antagonist in preparation of medicine for treating osteoarthritis, and further relates to a corresponding medicine composition.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a pharmaceutical composition for treating bone joints and its application. Background technique [0002] Osteoarthritis (OA) is the degeneration of the articular cartilage surface due to aging or mechanical stress, followed by the proliferation of new cartilage at the edge of the joint, joint deformation, and loss of fitness, and then develops into joint synovial inflammation disease. Osteoarthritis (OA) is a common disease characterized by progressive articular cartilage degeneration. The morbidity, teratogenicity and disability rate of OA are high, but its pathogenesis is still unclear and there is no effective treatment. [0003] Osteoarthritis-related disease typically manifests as cartilage loss and structural changes in the bursa, joint, and periarticular bone (Altman 1987; Altman et al., 1990). The damage of articular cartilage is one of the important problems of ost...
