The present invention relates to trans-epithelial membrane delivery systems, methods and kits that include an agent to penetrate the basement membrane, a membrane of the skin and mucosa previously known to be difficult to penetrate. In particular, the formulation includes a basement membrane disruptor that reversibly denatures or cleaves molecules of the basement membrane of the epithelial membrane. The formulation of the present invention further includes having at least one penetration agent, at least one vaso-modulator, and at least one active ingredient. In an embodiment, the penetration agent includes a solvent, a lipophilic agent, a hydrophilic agent, wherein the basement membrane disruptor, the vaso-modulator, and the active ingredient pass through the outer layers of the epithelial membrane. The basement membrane disruptor allows the vaso-modulator and the active ingredient pass through the basement membrane to smooth muscle. The active ingredient, once at the smooth muscle, is delivered locally to the tissue or systemically to the blood stream.

Trans-epithelial membrane drug delivery system

The present invention relates to transdermal delivery systems, methods and kits that include an agent to penetrate the basement membrane, a membrane of the skin previously known to be difficult to penetrate. In particular, the formulation includes a basement membrane disruptor that reversibly denatures the basement membrane of the skin. The formulation of the present invention further includes having at least one penetration agent, at least one vaso-modulator, and at least one active ingredient. In an embodiment, the penetration agent includes a solvent, a lipophilic agent, a hydrophilic agent, wherein the basement membrane disruptor, the vaso-modulator, and the active ingredient pass through the stratum corneum and epidermis. The basement membrane disruptor allows the vaso-modulator and the active ingredient pass through the basement membrane to dermis. The active ingredient, once at the dermis, is delivered locally to the tissue or systemically to the blood stream.

Transdermal drug delivery system

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.

Transdermal drug delivery using an osmolyte and vasoactive agent

The invention provides a topical formulation for treating pain comprising a nonsteroidal anti-inflammatory agent or a Cox-2 inhibitor and a gabapentin family member.

Transdermally-delivered combination drug therapy for pain

Methods and formulations for removing a tattoo by using a cell disrupter in combination with a vasodilator, and optionally one or more of an osmotic modifying agent, a chelation agent, and an occlusive modifying agent. Embodiments optionally further include using one or more of an antibiotic, anesthetic, penetration enhancer, excipient, carrier and vehicle.

Methods and compositions for tattoo removal

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.

Ibuprofen for topical administration

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.

Compositions for topical treatment of medical conditions including wounds and inflammation

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.

Control of blood vessel physiology to treat skin disorders

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.
