The monoethanolamine salt of N- (2-pyridyl) -2-methyl-4-hydroxy-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide in the particular crystalline form
The monoethanolamine salt of N- (2-pyridyl) -2-methyl-4-hydroxy-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide in the particular crystalline form
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.
