Abstract

The invention provides an ear drop which comprises voriconazole and one or more than one of its pharmaceutical salts, ambroxol and one or more than one of its pharmaceutical salts, and pharmaceutical adjuvants. The ear drop of the invention can effectively improve patient feeling of earache and ear fullness; the ear drop is prepared by the combination of ambroxol hydrochloride and voriconazole, and thus the application of the ear drop has significantly better effect than single application of a voriconazole ear drop or ambroxol hydrochloride, and has higher patient compliance than single application of a voriconazole ear drop, has a shorter treatment course; and it is concluded that the combination of a voriconazole ear drop and ambroxol hydrochloride for the ear drop has synergistic effect on disease cause elimination and function recovery.
