  • Patent number: 8741848
    Abstract: The present invention relates to a pharmaceutical composition that comprises polymeric microspheres containing epidermal growth factor (EGF) for the application, by the parenteral route, into the lower limbs of diabetic patients with cutaneous chronic ischemic ulcerative wounds. The pharmaceutical composition described herein, in contrast with the state of the art, is useful because reduce the administration frequency during the treatment and allows for the healing of the ulcerative wounds in a shorter time interval with respect to the injection of equivalent quantities of non-encapsulated EGF.

  • Publication number: 20090082537
    Abstract: A polymeric dendrimer-like structure with four branches of monomethoxy-polyethylene glycol that can be represented as: The carboxylic group of the previous structure can be functionalized for the production of conjugates of pharmaceutical interest. The binding of this dendrimer-like polyethylene glycol to therapeutic proteins improves their in vitro and in vivo stability.

  • Publication number: 20090074850
    Abstract: The present invention is related to the use of topical formulations that contain epidermal growth factor encapsulated in or associated to deformable or conventional liposomes to be applied on the surface of and around chronic ischemic skin lesions. The formulations of the present invention, in contrast with the previous art, are useful because they provide a high bioavailability of EGF in the tissue deep below the lesions and for preventing diabetic foot amputation.
