Extended-release ophthalmic formulations are described, containing the active principles in the form of high-viscosity solutions formed of a mixture of water and polyoxyethylene-polyoxypropylene copolymers (poloxamers) having approximately 70% of polyoxyethylene units and an average molecular weight of approximately 12,500, characterised in that they contain non-ionic surfactants as stabilisers. |
