Problems solved by technology

In the production process of etoricoxib tablets, the fluidity of the material before compression is a key indicator that affects the operability of large-scale production and the difference in tablet weight. All have been investigated, and the fluidity of the material before tableting has not been studied, so the tablet weight of etoricoxib tablets obtained varies greatly

Abstract

The invention relates to an optimization method of etoricoxib tablets, the steps are as follows: after uniformly mixing etoricoxib, calcium hydrogen phosphate anhydrous, internally added microcrystalline cellulose, disintegrant and internally added lubricant, dry granulation, Obtain granule products; mix granule products, external microcrystalline cellulose and external lubricant to obtain a mixture; take a small amount of mixture for fluidity index test, if the test results meet the requirements, go to the next step, otherwise readjust the formula until the test results meet the requirements Requirements: Tablets are obtained by compressing the mixture, and etoricoxib tablets are obtained after coating with coating materials; the in vitro dissolution performance test is performed on the tablets before coating. This optimization method effectively controls the fluidity of the material before tablet compression, so that the tablet weight variance is lower.

Description

technical field [0001] The invention relates to a medicine for treating arthritis, in particular to an etoricoxib tablet and an optimization method thereof. Background technique [0002] Etoricoxib (etoricoxib) is a highly selective cyclooxygenase 2 (COX-2) inhibitor, chemical name: 5-chloro-2-(6-methylpyridin-3-yl)–3-(4 -methylsulfonylphenyl)pyridine. It went on the market in Mexico in March 2002, and in the UK in April 2002. The dosage form on the market is a film-coated tablet. It is clinically used for the treatment of osteoarthritis, rheumatoid arthritis, acute gouty arthritis, dental surgery related to acute pain, primary dysmenorrhea and chronic musculoskeletal pain, and chronic low back pain. In the production process of etoricoxib tablets, the fluidity of the material before compression is a key indicator that affects the operability of large-scale production and the difference in tablet weight. All have been investigated, and the fluidity of the material before ...
