OPHTHALMIC COMPOSITIONS BASED ON POLYUNSATURATED OMEGA-3 AND OMEGA-6 FATTY ACIDS

摘要

The invention concerns topical compositions for the prevention and treatment of ocular pathologies, in particular inflammatory keratites and con- junctivites and dry eye syndrome, containing as active ingredients polyunsatu- rated fatty acids of the types omega-3 and omega-6, and specifically EPA (eicosapentaenoic acid ), DHA (docosahexaenoic acid) and GLA (?-linolenic acid), mixed with vitamin E acetate and formulated in a stable composition in hydrogel, i.e. in dispersed form in an aqueous vehicle containing one or more gelling polymers. The proposed compositions are particularly indicated for use as artificial tears.
