Abstract

See full text

The present invention provides a biodegradable microdepot delivery system for topical delivery of active ingredients through the skin surface of a subject. The configuration, dimension, and chemical composition of the microdepots allow a relatively short dissolution time of less than 5 minutes while insertion ratio of the microdepots can reach more than 60%, some of which can even reach about 97%, under exertion of a relatively low pressing force. The present invention also provides a method for fabricating the biodegradable microdepot delivery system and a polymeric solution for forming the same.
