| abstract |
An object of the present invention is to provide a composition for a non-aqueous patch preparation having excellent adhesiveness capable of sustaining drug release. The patch preparation of the present invention can improve the adhesiveness and drug release properties of the patch preparation by adding powder components (fillers, etc.). As a result, the long-term maintenance of the adhesiveness of the tape preparation makes it possible to enhance the transdermal absorption and sustained release of the drug. By using the composition for patch preparation containing this powder component, a drug, regardless of the type of drug, is dissolved in an organic solvent or an ionic liquid to prepare a drug solution containing an organic solvent, which is incorporated into the drug solution of the present invention. In non-aqueous patch formulations, and thus formulations with improved transdermal absorption and improved sustained release can be prepared. |
