Skin wound healing promoters

摘要

The present invention provides healing promoters for skin wounds such as rupture, abrasion, surgical incision, skin ulcer and burn. Coexistence of Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2 or Phe-Gly-Leu-Met-NH2 with insulin-like growth factor-I exhibits a remarkable promotive action on healing the skin wounds. Accordingly, combined administration of at least one of the substance P analogs and pharmaceutically acceptable salts thereof with the insulin-like growth factor exhibits a promotive effect on epidermal extension and a promotive effect on healing the skin wounds.
