Abstract

The invention relates to a drug composition for treating local inflammation, which uses methylprednisolone palmitate as an active composition. The drug composition consists of the methylprednisolone palmitate as the active composition and an inactive composition suitable for local injection, and is used for treating local inflammation of people or mammal through local injection.

Description

Technical field: [0001] The invention relates to the technical field of medicine, and relates to the application of methylprednisolone palmitate in the preparation of medicines for treating local inflammation Background technique: [0002] Rheumatoid arthritis (RA) and osteoarthritis (OA) are common chronic inflammatory joint diseases. At present, the drugs for treating such diseases are mainly steroids and non-steroids. Due to the definite curative effect of steroids, they are necessary for the treatment of severe patients, and their role is irreplaceable by non-steroids. At present, the dosage forms of steroid drugs on the market are mainly divided into two categories, one is solution type (including freeze-dried powder injection) injection, and the other is suspension injection. The former can be "intravenously injected", "intramuscularly injected" and "joint cavity injected", but the elimination speed is fast, and the effective concentration cannot be maintained in the ...
