The present invention provides a Fentanyl-containing percutaneously absorbable adhesive preparation, which is obtained from economic starting materials, has a constitution simpler than that of conventional ones, has sufficient skin permeability, and which permits control of skin permeability by changing the mixing ratio of two kinds of polyisobutylene having different molecular weights, a tackifier and an organic liquid. Specifically, the present invention provides a percutaneously absorbable adhesive preparation comprising a support and an adhesive layer laminated on one surface thereof, wherein the adhesive layer comprises Fentanyl, two kinds of polyisobutylene having different molecular weights, a tackifier and an organic liquid compatible with the aforementioned two kinds of polyisobutylene and the aforementioned tackifier.
摘要:
A composition for percutaneous administration containing a nicotinic ester represented by formula (I) ##STR1## or an isonicotinic ester represented by formula (II) ##STR2## wherein R and R' each represents an alkyl group having 5 or more carbon atoms,with or without a specific polar compound. The composition improves percutaneous absorption of an active ingredient.
摘要:
The present invention relates to a patch containing a substrate, a non-crosslinked adhesive layer (A) containing a drug laminated on one surface of the substrate and a crosslinked adhesive layer (B) laminated on the adhesive layer (A). According to the present invention, the percutaneous absorbability of the drug can be improved, and a patch free of problems such as adhesive residue and adhesive bleed can be provided.
摘要:
The present invention relates to a patch containing a substrate, a non-crosslinked adhesive layer (A) containing DMAE or a pharmacologically acceptable salt thereof laminated on one surface of the substrate and a crosslinked adhesive layer (B) laminated on the adhesive layer (A). According to the present invention, the percutaneous absorbability of DMAE or a pharmacologically acceptable salt thereof can be improved, and a patch free of problems such as adhesive residue and adhesive bleed can be provided.
摘要:
The present invention provides a percutaneous absorption preparation which comprises a skin contact base containing therein at least one active ingredient selected from the group consisting of biperiden, trihexyphenidyl and pharmacologically acceptable salts thereof in an amount of from 0.5 to 60% by weight. The percutaneous absorption preparation makes it possible to permit the percutaneous absorption of biperiden, trihexyphenidyl or pharmacologically acceptable salt thereof as an active ingredient so that the medicament can be used effectively and at the same time, pharmacological effects can be sustained long and administration can be carried out conveniently. In addition, the active ingredient contained in it can be maintained stably.
摘要:
A percutaneous absorption type preparation comprising a support and a plaster layer laminated thereon, which composes tulobuterol in a proportion of not less than 5 wt % in a dissolution state and an adhesive. The preparation of the present invention retains the active ingredient, tulobuterol, at a high concentration in a complete dissolution state in the plaster layer. Therefore, it is free of time-course changes in drug releasing property and adhesive property caused by precipitation of drug crystals with the lapse of time. The inventive preparation is superior in percutaneous absorption of the drug, particularly percutaneous absorption rate at the initial stage of the administration; shows superior duration of efficacy by maintaining effective blood concentration for a long time; and is associated with less changes with the lapse of time in adhesive property such as adhesion to the skin.
摘要:
The present invention relates to a composition for percutaneous administration which can enhance percutaneous absorption of a physiologically active ingredient and a method of enhancing percutaneous absorption of a physiologically active ingredient employing the same.
