A first alternative to a composition for preventing or retarding degradation of a functional coating on a medical device comprising an antioxidant selected from gallic acid or a derivative thereof. A second alternative to a composition for preventing or retarding degradation of a functional coating on a medical device includes carboxymethyl cellulose or a derivative or salt thereof. The use of the compositions for preventing or retarding degradation of a functional coating on a medical device from reactive species generated during exposure of radiation, and a wetting agent comprising the compositions, are also provided. The wetting agent prevents or retards the hydrolytic degradation of the coating during the intended shelf-life of the wetted coated product.

Biocompatible compositions, in particular for the preparation of a biodegradable coating for medical articles, include a biocompatible thickening polymer and a chitosan derivative comprising D-glucosamine units of the following formula (I):

##STR00001##

wherein X is an alditolic or aldonic polyol residue of the following formula (II):

##STR00002##

wherein: R is CH.sub.2 or CO; R1 is hydrogen, a monosaccharide moiety or an oligosaccharide moiety; R2 is OH or NHCOCH.sub.3.

The present invention also relates to uses of the disclosed compositions, to a kit of parts including a composition in powder form and to a method for the preparation of a biocompatible composition in gel form.
