  • Publication number: 20230122491
    Abstract: The present invention provides a composition for a non-aqueous patch preparation having an excellent adhesibility which can sustainedly release a drug. The patch preparation of the present invention can improve the adhesibility thereof as well as the release property of a drug by the addition of powder ingredient (e.g. a filler). As a result, the long-time sustention of the adhesibility of patch preparations can achieve the improvement of the transdermal absorbability and the sustained release of a drug. By the use of a composition for a patch preparation comprising this powder ingredient, a drug, regardless of the type of a drug is dissolved in an organic solvent or an ionic liquid to prepare a drug solution comprising the organic solvent, the drug solution is incorporated into the non-aqueous patch preparation of the present invention, and thereby a preparation with the improved transdermal-absorbability and sustained release can prepared.

  • Patent number: 8568746
    Abstract: Disclosed is a transdermal composition, which uses high-purity phosphatidylcholine that is most susceptible to oxidation and the like, and which exhibits high stability and high migration into the skin. Specifically, a transdermal composition having good stability and migration into the skin is able to be obtained by preparing a transdermal composition (a colloidal dispersion liquid of phosphatidylcholine) that contains high-purity phosphatidylcholine, carnitine, a polyhydric alcohol and water. Since the transdermal composition does not contain an oleaginous base (an oil component), the transdermal composition has skin compatibility and is thus useful as a therapeutic agent or a cosmetic preparation. In addition, phosphatidylcholine and carnitine have an effect of achieving good migration into the skin and are capable of promoting systemic or local lipid metabolism in subcutaneous adipose tissues.
