摘要:
Disclosed is a percutaneous absorption preparation for treatment of dementia that comprises rivastigmine or its pharmaceutically acceptable salt as an active ingredient, a styrene-isoprene-styrene block copolymer, a tackifier resin, and a plasticizer, which preparation contains a small amount of rivastigmine but allows a sufficient amount of the active ingredient penetrated into the skin to achieve an effective treatment of dementia.

A dual drug containing adhesive transdermal drug delivery system comprising: a support layer, a first drug containing adhesive layer and a second drug containing adhesive layer each of said layers having a proximal and distal surface wherein each layer is positioned adjacent to the other with each layer having its distal surface laminated to said support layer, and a peelable backing layer positioned over and laminated to the proximal surface of said first and second adhesive layers is disclosed.
摘要:
The patch for tooth whitening of the present invention includes a tooth-adhering layer (1) containing erodible polymer complexes formed by hydrogen bonding of a polymer with a carboxyl group (—COOH) and a polymer with a carbonyl group (—C═O) or ether group (—O—) and a tooth whitening agent; and an erosion rate-controlling layer (2) containing a mixture of a hydrophilic polymer and a film-forming polymer, wherein the patch is in a film form and is characterized by being eroded until extinguished after releasing the tooth whitening agent. When applied to the teeth, the patch releases a peroxide tooth-whitening agent while being hydrated by water in the mouth during a prescribed period, and thereafter, eroded until extinguished, thereby not requiring an additional detaching work from the teeth. Therefore, the patch is convenient in use and greatly reduces an obstruction sensation. Moreover, the patch has an excellent whitening effect.
