Rilastat eye drops can be used to treat dry eye. Rituxan is a novel small molecule integrin antagonist that inhibits T-cell mediated inflammation by blocking the binding of two important cell surface proteins, thereby reducing the overall inflammatory response. This reduces the inflammatory response in the eye and protects the tear-producing glands of the eye from damage and atrophy due to inflammation, thus preventing dry eye. Ritalin eye drops belongs to a new drug for the treatment of dry eye, the use of which may cause allergies and other adverse reactions, and is not recommended for self-medication. Patients need to go to the ophthalmology department of the hospital in time for examination to determine the type and severity of dry eye, and use the medication reasonably under the guidance of the doctor.
