摘要:
The present invention relates to salts of azelastine having improved solubility in water. The salts of the present invention are prepared by reacting azelastine with acetic acid, gluconic acid, lactic acid or malic acid. A pharmaceutical composition may be prepared containing an azelastine salt and a pharmaceutically-acceptable carrier or diluent therefor. The pharmaceutical composition is useful in the treatment of allergies, asthma, inflammatory and psoriasis disorders and provides a cytoprotective effect.
