Abstract
The storage stability of a polymeric article susceptible to hydrolytic degradation, e.g., an absorbable suture manufactured from a polymer of glycolic acid, glycolide, lactic acid, lactide or combination thereof, is improved by applying a storage stabilizing amount of at least one water soluble hygroscopic polyhydroxy compound and/or ester thereof, e.g., glycerol, monoacetin, diacetin, and the like, to the article as storage stabilizing agent, said agent being retained by the article prior to sealing of the enclosure in which the suture is packaged.
