ESTERS OF ARYLPROPIONIC ACIDS ENDOWED WITH AN ANTI- INFLAMMATORY ACTIVITY, PROCESS FOR THEIR PREPARATION, AND RELATED PHARMACEUTICAL COMPOSITIONS

摘要

ESTERS OF ARYLPROPIONIC ACIDS ENDOWED WITH AN ANTI-INFLAMMATORY ACTIVITY, PROCESS FOR THEIR PREPARATION, AND RELATED PHARMACEUTICAL COMPOSITIONS. The present invention concerns diesters of polyethylene glycols (with n ranging between 4 approximately and 100 approximately) with 2-arylpropionic acids (known as antiinflammatory agents). Said esters, while possessing all the characteristics of low toxicity and gastric injuring effects shown by the related acids, differ advantageously from the latter because their anti-inflammatory activity is much more prolonged, and their bioavailability markedly better.
