Micropores created in the skin by MNs reseal because of normal healing processes of the skin, thus limiting the duration of the drug delivery window. Pore lifetime enhancement strategies can increase effectiveness of MNs as a drug delivery mechanism by prolonging the delivery window. Fluvastatin (FLU) was used to enhance pore lifetime by inhibiting the synthesis of cholesterol, a major component of the stratum corneum lipids. The skin recovered within a 30-45-min time period following the removal of occlusion, and there was no significant irritation observed due to the treatment compared to the control sites. Thus, it can be concluded that localized skin treatment with FLU can be used to extend micropore lifetime and deliver drugs for up to 7 days across MN-treated skin.
专利号:US-8470932-B2 优先权日:2010-04-08 标题 :Scalable process for synthesis of a curable wax 发明人:ROBINSON SARAH J P; ENRIGHT THOMAS E; BELELIE JENNIFER L 权利人:ROBINSON SARAH J P; ENRIGHT THOMAS E; BELELIE JENNIFER L; XEROX CORP 摘要:The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH 3 —(CH 2 ) n —CH 2 OH, where n=22-24, are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the presence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than 85° C., and solidifying the acrylate. The methods may thereby provide safe and cost effective methods for curable wax production at large scale.

The methods may include reacting a wax having a transformable functional group and a curable compound in the absence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than about 85° C., solidifying the acrylate, removing the acrylate, and removing a fouled material in the reactor by emulsification.
