摘要:
An embeddable micro-needle patch for transdermal drug delivery and method of manufacturing the same are disclosed. The embeddable micro-needle patch for transdermal drug delivery comprises a supporting substrate, on which the surface includes a plurality of extruded supporting shafts a biodegradable carrier, which is formed of biodegradable polymer material and disposed on the supporting shaft and drugs, which are encapsulated in the biodegradable carrier. When the embeddable micro-needle patch for transdermal drug delivery is attached to the skin for a predetermined time, the biodegradable carrier is separated from the supporting shafts and embedded into the skin, and the biodegradable carrier may swell and then degrade, so as to release the drugs, which are encapsulated in the biodegradable carrier, at a rate of 1%˜99% loaded drug per day into the skin. Accordingly, velocity of releasing the drugs may be regulated, so as to sustain the drug efficacy.
