  • Patent number: 10751309
    Abstract: A formulation and method for delivery of bioactive substances when applied to, or within, the skin or other exterior region of a mammal. for example, a patient, includes a vasoactive agent; an osmolyte; and an active ingredient. The formulation is sufficiently hygroscopic so as to create a condition of hypertonicity when absorbed by the skin. When the formulation is applied to the skin, the vasoactive agent can be delivered to the dermis so as to contact the vasculature of a patient.

  • Patent number: 9561174
    Abstract: Set forth herein is a preparation of ibuprofen (2-(4-isobutylphenyl) propionic acid) in the free acid form that is suitable for topical administration. The topical ibuprofen formulation is prepared by dissolving the free acid form of ibuprofen, or preparing a homogeneous suspension of the free acid form of ibuprofen, in the presence of a pharmaceutically acceptable solvent so as to produce a topical drug formulation compatible with the penetration of 2-(4-isobutylphenyl) propionic acid through the skin tissue. Topical formulations of ibuprofen can be based on a pharmaceutically acceptable solvent such as, e.g., a pyrrolidone solvent or dimethylacetamide.

  • Patent number: 8802085
    Abstract: A method for treating a patient suffering from a wound, ulcer, or inflammation includes providing a topical formulation comprising a carrier and a combination of active ingredients that includes at least one retinoid and at least one blood vessel dilator, and applying the topical formulation to the skin of the patient to cause healing, accelerated healing or prevention of the wound, ulcer or inflammation. Additional active ingredients may include a promoter of mitochondrial function or an antioxidant.

  • Publication number: 20130245538
    Abstract: In a method for treating an affected skin region of a patient having a skin disorder, a vasodilation composition is applied to an affected skin region of a patient, the affected skin region exhibiting a skin disorder characterized by at least one abnormal blood vessel, and the affected skin region is then treated so as to non-invasively disrupt tissue architecture, e.g., by inducing ischemia, of the at least one abnormal blood vessel. A vasoconstriction composition can then be applied to the skin region to cause vasoconstriction of the at least one blood vessel in order to promote healing.

  • Patent number: 8354116
    Abstract: The synthesis and use of bifunctional molecules to improve the topical and transdermal delivery efficiency of various types of therapeutic agents or agents designed to promote the transdermal delivery of those therapeutic agents either into the skin tissue or into the systemic circulation. Three major classes of molecules are covalently joined as bifunctional substances; chemical vasodilators, passive dermal penetration enhancers and therapeutic or diagnostic drugs. Chemical vasodilators may be delivered into the skin to increasing the blood flow in a tissue that has compromised circulation or they may be used as part of a delivery vehicle to promote the delivery of the drug. Passive dermal penetration enhancers are those chemicals that promote the passive penetration of drugs and other chemicals through the stratum corneum and epidermis of the skin tissue. Drugs and diagnostic agents are the third group of chemicals that are candidates for the linkage of molecules.

  • Patent number: 6635274
    Abstract: An efficient transdermal delivery system for delivering an active ingredient to the blood supply of a living body, comprising a vasodilator, an active ingredient, and a permeation enhancer for the active ingredient. The components of this mixture are combined in a manner that dissolves them into solution, eliminating the need for a polymeric binding agent and thus diminishing the total molecular weight of the mixture and increasing the penetration and delivery efficiency of the active drug molecules.
