The present invention relates to a pharmaceutical preparation for transdermal administration, in which clonidine and/or its hydrochloride is administered into the body through the skin. The present invention relates to a pharmaceutical preparation for transdermal administration for absorbing clonidine and/or its hydrochloride through the skin. In recent years, instead of oral administration or injection administration of drugs, transdermal administration has been attracting attention for the purpose of prolonging pharmacological effects and reducing side effects, and drug types have also changed from topical drugs to systemic drugs. However, it has been difficult to prevent the content of medicinal ingredients from decreasing due to oral changes in the drug in the formulation and to stably contain the drug for a long period of time. Transdermal absorption preparations using clonidine and/or its hydrochloride, which are transdermal absorbable systemic drugs, are disclosed in JP-A-54-20129 and JP-A-57-
150614, which control the release rate
・Although the drug sufficiently satisfies its purpose in terms of its role and pharmacological effects, it is still insufficient in terms of long-term stability of the drug (J). In order to solve the above problems (11), as a result of repeated research, clonidine and/or
We have discovered that by incorporating at least one selected from polyphosphoric acid and its salts together with its hydrochloride, the stability of the drug is improved and the content of the medicinal ingredient is prevented from decreasing over a long period of time. This led to the present invention. That is, the present invention provides a drug for transdermal administration, in which clonidine and/or its hydrochloride is stably incorporated in a preparation to suppress decomposition reactions, and the drug is administered transdermally into the body. It is a preparation with a glass transition temperature of 170°C to 11°C.
