Abstract
A first alternative to a composition for preventing or retarding degradation of a functional coating on a medical device includes 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.
