Abstract:
A transdermal preparation is provided to promote the drug absorption by the skin hydration through a hydrophobic adhesive layer, show continuous and high effect of a drug by maintaining the thermodynamic activity of the hydrophobic drug in an adhesive caused by moisture discharged from skin and be able to reduce the cost and the time due to a very simple preparing process. A transdermal preparation for a hydrophobic drug comprises a supportive layer(1) which is the uppermost portion of a layered structure and has the elasticity; a hydrophobic adhesive layer(2) which is layered under the supportive layer and prevents the loss of moisture absorbed from skin and the reverse conversion of the drug; and a drug containing adhesive layer(3) which is layered under the hydrophobic adhesive layer, includes a drug and attaches the transdermal preparation to the skin and is characterized in that the drug adhesive layer includes a hydrophobic drug such as a non-steroidal antiphlogistics and an absorption promoting agent, where a hydrophobic adhesive of the hydrophobic adhesive layer is selected from the group consisting of polyisobutylene adhesive, styrene-isoprene-styrene adhesive, and styrene-butadiene-styrene adhesive, the drug containing adhesive layer is an acrylate polymer made from acrylate, hydroxypropyl acrylate, acrylamide, acrylamide vinyl acetate, vinyl derivative, methacrylate, hydroxypropyl methacrylate and methacrylamide. The preparation further comprises a release layer(4) which is layered under the drug adhesive layer and protects the drug adhesive layer before use.
Abstract:
A transdermal preparation is provided to continuously allow a highly concentrated hydrophobic drug to be absorbed into skin until a patch is detached from the skin with minimized skin side effects and provide the enough adhesive capability during the time of exhibiting the medical efficacy by being attached to the skin. A transdermal preparation for a hydrophobic drug comprises a supportive layer(1) which is the uppermost portion of a layered structure and has the elasticity; a hydrophobic adhesive layer(2) which is layered under the supportive layer and prevents the loss of moisture absorbed from skin and the reverse conversion of the drug; and a drug adhesive layer(3) which is layered under the hydrophobic adhesive layer, includes a drug and attaches the transdermal preparation to the skin and is characterized in that the drug adhesive layer includes a hydrophobic drug such as a non-steroidal antiphlogistics and an acryl adhesive agent and the acryl adhesive agent includes a hydrophilic monomer promoting the skin absorption from the skin and is selected from the group consisting of acrylic acid, methyl methacrylate, ethyl acrylate, hydroxyethyl acrylate, butyl acrylate, octyl acrylate, 2-ethylhexyl acrylate, and hexyl acrylate. The preparation further comprises a release layer(4) which is layered under the drug adhesive layer and protects the drug adhesive layer before use.
Abstract:
A composition for transdermal absorption is provided to increase solubility of non-steroidal anti-inflammatory drug as an effective ingredient by using a small amount of solubilizer, thereby containing high concentration of effective ingredient without skin irritation. A formulation comprising a polymeric matrix is also provided to maximize skin absorption of the effective ingredient. A composition for transdermal absorption comprises 0.1-50 wt.% of a non-steroidal anti-inflammatory drug, 0.01-10 wt.% of alkali metal-containing alcohol derivatives represented by the formula(1): M-O-R in which M is a Group I metal, O is oxygen and R is C1-5 alkyl as a solubilizer, 40-98 wt.% of a polymer adhesive and a volatile solvent. A formulation for transdermal absorption comprises a release paper, a polymeric matrix(2) prepared by coating the release paper(3) with the composition for transdermal absorption, and a support(1), sequentially, and has the thickness of 10-120 mum.

Abstract:
PURPOSE: A method for preparing a water-insoluble gel composition is provided to minimize molecular weight reduction of polysaccharides using a small amount of a crosslinking agent and to ensure excellent strength and stability. CONSTITUTION: A method for preparing a water-insoluble gel composition comprises: a step of mixing water-soluble polysaccharides, an epoxy crosslinking agent, a basic compound, and a solvent; and a step of drying the mixture under vacuum at 1-30 deg. C to remove the solvent. The vacuum pressure is 1-30 mmHg. The solvent is removed by concentrating the water soluble polysaccharides in a concentration of 50-99 wt%. The molecular weight of the water soluble polysaccharides is 500-5,000 kDa. [Reference numerals] (AA) Volume of gel(%); (BB) Example 11
