Agent for treatment of dry eye characterized by combining P2Y₂ receptor agonist and hyaluronic acid or salt thereof, method for treating dry eye, and use of the P2Y₂ receptor agonist and hyaluronic acid or salt thereof

摘要

An agent for treatment of dry eye comprising a combination of a P2Y₂ receptor agonist at a therapeutically effective concentration and hyaluronic acid or a salt thereof at a therapeutically effective concentration, which agent has a dosage form of an ophthalmic agent, can promote the secretion of tear remarkably and can improve corneal epithelial disorders remarkably, and is therefore expected to be a novel agent for treatment of dry eye.
