Abstract
The invention provides an ophthalmic product containing rebamipide, which has a transparency enough to be agreeable feeling on using it and has neutral to weakly acidic pH not to injury of the keratoconjunctiva of a patient suffering from dry eye. An aqueous suspension of crystalline rebamipide which has an improved transparency is provided by adding an aqueous solution of rebamipide dissolved by a base such as sodium hydroxide or an aqueous solution of a salt of rebamipide to an aqueous acidic solution such as hydrochloric acid containing at least one of the compounds selected from water-soluble polymers and surfactants, and mixing them.
