• 世界保健機関（WHO）

  Azapropazone, which has anti-inflammatory, analgesic and antipyretic activity, was introduced in 1970 for the treatment of rheumatic disorders. Although sometimes classified as a pyrazolone derivative, the relationship with this group of compounds has been disputed and classification as a benzotriazine derivative might be preferable. Although, to date, it has not been associated with blood dyscrasias, some regulatory authorities have applied the same rigorous restrictions to its indications as they have applied to pyrazolone derivatives. The World Health Organization was informed that as of December 1987 azapropazone was available in some 27 countries.
