Prometheon Pharma says it has developed a breakthrough transdermal drug delivery system that can passively deliver large molecules like human growth hormone (which has a size of 2,200 daltons) across the skin. It just announced that it is preparing to launch a cosmetic hair growth gel for transdermal delivery of IGF-1 in the second half of the year. Prometheon is exploring other uses of its transdermal delivery system, especially in diabetes care. The company told FierceDrugDelivery that is actively seeking a Big Pharma partner to deploy its clinical-stage patch for transdermal delivery of insulin. Release
