METHOD FOR PREPARING ALKALINE SALTS OF 4- HYDROXY- 2- METHYL- N- (2- PYRIDYL)- 2H- 1, 2- BENZOTHIAZINE- 3- CARBOXAMIDE

摘要

A process has been developed for preparing the sodium, the monoethanolamine and the diethanolamine salts of piroxicam, in which the salt is deposited on a pharmaceutically-acceptable carrier. The compositions so obtained are useful for preparing pharmaceutical dosage forms of piroxicam, from which piroxicam is rapidly absorbed from the gastrointestinal tract after oral administration to mammals. These latter dosage forms are particularly suitable when it is desired to use piroxicam as an analgesic agent, where rapid onset of action is necessary.
