CONCLUDING REMARKS:

CONCLUDING REMARKS The ultimate goal of penetration enhancer is to assure that the compounds are delivered preferably at specific rate to remain at topical site or to reach the systemic circulation. The customization drug vehicles and enhancers may be most promising future direction for transdermal enhancement and drug delivery. 28
