Definitions
- the present invention provides a method for stably presenting 6-amino-5-chloro-1- 1-isopropyl-12- (4-methyl-11-piperazinyl) benzimidazole or an acid addition salt thereof in a preparation, and transdermally in vivo.
- 6-Amino-5-chloro-1-monoisopropyl-1- (4-methyl-11-piperazinyl) benzimidazole or an acid addition salt thereof are excellent. It is known that it has a serotonin 3 receptor antagonistic action and is a useful compound as an antiemetic for vomiting associated with cancer chemotherapy with cisplatin or the like (Japanese Patent Application Laid-Open No. 5-174449).
- transdermal preparations containing the above-mentioned benzimidazole compound as an active ingredient are not yet sufficient in terms of the stability of the benzimidazole compound, which is the main drug, in the preparation.
- An object of the present invention is to provide a transdermal absorbability of a benzimidazole compound and a long-lasting effect.
- An object of the present invention is to provide a preparation for transdermal administration which is excellent in stability and has improved stability of a benzimidazole compound as an active ingredient in the preparation.
- the present invention is as follows.
- a transdermal preparation comprising a pressure-sensitive adhesive layer containing an acrylic copolymer, a benzimidazole compound, and 2-mercaptobenzimidazole formed on at least one surface of a support.
- the pressure-sensitive adhesive layer comprises an acrylic copolymer, a fatty acid ester compatible with the acrylic copolymer, a benzimidazole compound, and 2-mercaptobenzimidazole.
- the pressure-sensitive adhesive layer contains an acrylic copolymer and a fatty acid ester in a weight ratio of 1: 0.25 to 12 and the acryl-based copolymer is crosslinked. Dosage form.
- ⁇ The formulation for transdermal administration according to ⁇ , wherein the crosslinking is performed by at least one crosslinking agent selected from the group consisting of an alcoholate and a metal chelate containing titanium or aluminum, and a trifunctional isocyanate.
- the benzimidazole compound is absorbed transdermally and an excellent serotonin 3 receptor antagonist is obtained. It has a long-lasting effect, and its action lasts for a long time.
- the stress applied to the skin surface during release of the preparation can be reduced and dispersed, and skin adhesion and skin irritation The balance of properties is good.
