Problems solved by technology

[0003] Existing eye drops have general effects during use, such as eye drops containing sodium hyaluronate. Sodium hyaluronate is unstable under light and heat and is easy to degrade. It is not suitable for long-term storage at room temperature. At the same time, hyaluronate Sodium is a kind of biological macromolecule mucopolysaccharide, which is easy to be polluted and grow bacteria, so that its stability and moisturizing effect are average, and it cannot relieve dry eyes. Therefore, we propose a olopatadine hydrochloride Eye drops and preparation method thereof
