Abstract
Paroxetine salt compositions having improved stability are formed by controlling the pH to 6.5 or less. The compositions can be made with the aide of water without significant coloration problems. The paroxetine salts include paroxetine hydrochloride salts but preferably use paroxetine sulfonate salts such as paroxetine methane sulfonate.
