Scientists have confirmed the feasibility of using a new drug delivery system - the basis for a battery-powered skin patch - to administer medication that shows promise for treating peripheral artery disease (PAD) and healing stubborn skin ulcers and burns. The needle-free delivery of the medication, which cannot be given by mouth and can have side effects when injected, is reported in the ACS journal, Molecular Pharmaceutics. Yogeshvar Kalia and colleagues explain that the medication consists of fibroblast growth factors (FGFs), proteins that have shown promise for treating skin conditions and PAD, which causes pain in the legs, buttocks, and feet due to blocked arteries in the legs.
