ANTI-IMFLAMMATORY POLYMORPHIC MONOETHANOLAMINE SALT OF N-(2-PYRIDYL)-2-METHYL-4-HYDROXY-2H-1,2-BENZOTHIAZINE-3-CARBOXAMIDE 1,1-DIOXIDE COMPOUND; COMPOSITION AND METHOD OF USE THEREFOR

摘要

A novel crystalline form of the monoethanolamine salt of N-(2-pyridyl)-2-methyl-4-hydroxy-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide has been prepared. This novel crystalline form is designated as polymorph I and is useful in therapy as a non-steroidal anti-arthritic agent. Methods for preparing this polymorph from readily available materials are provided.
