Abstract
The present invention concerns diesters of polyethylene glycols (with n ranging between 4 approximately and 100 approximately) with 2-arylpropionic acids (known as anti-inflammatory agents). These 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 bio-availability markedly better.
