BACKGROUND OF THE INVENTION Betahistine mesylate is used as a therapeutic and prophylactic drug for Meniere's syndrome and is currently orally administered mainly for the treatment of dizziness attacks and for the prevention of these attacks. To prevent seizures, this drug is administered three times a day after meals, but in order to relieve the patient from the annoyance of such frequent administration and to give the patient peace of mind. It is desired to develop a dosage form whose application will be effective once a day for a long time. In recent years, the skin has attracted attention as an administration site capable of sustaining the action of a drug once a day for a long period of time, and the present inventor has found that transdermal absorption of betahistine mesylate using the skin as an administration route. Intended to develop a formulation.

However, since the skin is also a protective film for protecting the living body from the external environment, it is generally not easy to absorb the drug from the skin, and application of betahistine mesylate to a sufficient amount by applying it to a small skin area is difficult. In order to obtain various therapeutic effects, it is necessary to prepare a percutaneous absorption preparation using a base that promotes skin permeability of betahistine mesylate.
