A free-flowing, amorphous paroxetine hydrochloride composition suitable as a therapeutic agent for premature ejaculation can be prepared by dissolving paroxetine free base in a hydrochloric acid-ethanol solution followed by drying. The present compositions comprise amorphous paroxetine hydrochloride and at least one hydroxyl-bearing compound. In one preferred embodiment, the hydroxyl-bearing compound is ethanol and the amount of ethanol present in the amorphous product is in the range of 1 to 4 weight percent based on paroxetine hydrochloride. The amorphous product is stable and substantially non-hygroscopic. |
