An active transdermal medicament patch includes a planar substrate with a therapeutic face releasably retainable against the skin of a patient. A return electrode and a medicament matrix susceptible to permeation by medicament are secured at separated locations on the therapeutic face. Each electrically conductively engages the skin, when the substrate is retained thereon. A power source carried on the substrate is electrically coupled between the medicament matrix and a programmed microprocessor also carried on the substrate. A substantially invariant voltage presented at an output contact of the microprocessor is applied during a predetermined therapy period across the skin between the medicament matrix and the return electrode, inducing transcutaneous migration of medicament into the skin at a substantially constant rate. A light-emitting diode carried on the substrate and coupled to the microprocessor communicates that the patch is operating.

The transdermal pharmaceutical composition may be topically administered to prevent magnesium deficiency or imbalances caused by magnesium deficiency.

A monolithic device for transdermal administration of an active pharmaceutical ingredient which is selected from propargylamines and rivastigmine and is liquid at 25° C., has an adhesive matrix layer which includes the active ingredient in an acrylic polymer pressure sensitive adhesive without cross-linker agent containing a metal atom, the adhesive having a shear value of between 1.5 and 15 hours, and further includes a non-volatile coadjuvant selected from squalene and triethylcitrate present in the layer in an amount of 1 to 15 wt %. The combination provides good release of the drug in use, reduces loss of the drug during a drying step in manufacture, reduces chemical interaction of the layer with the drug and achieves low level of skin irritation.

The invention herein relates to a transdermal drug delivery systern for anti-Inflammatory analgesic. agent comprising diclofenac diethylammonium salt, wherein a backing film (1), a matrix layer (2) containing active ingredients, a release liner (3) which is removed before application onto the skin are laminated therein. Mome particularly, the invention herein relates to a transdermal drug delivery system for anti-inflammatory analgesic agent comprising diclofenac diethylammonum salt, wherein the transdermal penetration and adhesion of the patch to the body are enhanced by means of a matrix layer which comprises a diclofenac diethylammonum salt as active ingredient in addition to acrylic polymer as adhesive constituent, non-ionic surfacant as absorption enhancer, terpene and dissolution assistant, and the volatile and non-volatile constituents of the composition arc separately applied therein for significantly reducing the manufacturing time thereof.

The present invention relates to the field of transdermal drug delivery. More specifically, the present invention relates to drug reservoir materials for use in transdermal drug delivery devices. The drug reservoirs of the present invention comprise a polyurethane polymer which can be processed at temperatures below those which cause degradation of temperature sensitive drugs and/or excipients. The present invention is also directed to tailoring the release characteristics of the polyurethane material to accommodate a range of suitable drugs to be delivered from the transdermal drug delivery device and/or provide a range of delivery rates for a particular drug.

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.

The present invention describes a system and method for reducing the abuse potential of drugs, particularly or especially narcotic agents, in transdermal drug delivery systems. This is achieved by designing the transdermal drug delivery system such that when the active drug is extracted out of the transdermal delivery system, a deterrent agent is also timely co-extracted upon introduction of the system to an extraction solution where abuse may normally be allowed take place. Preferably, the deterrent agent of the present invention is capable of inducing or causing one or more intensely repugnant effects within the abusing person, thus reducing the potential for abuse of the active drug formulation.

Described herein are silicone-containing acrylic polymers useful, for example, in transdermal drug delivery compositions, to methods of making and using them, to transdermal drug delivery compositions comprising them, and to methods of making and using such transdermal drug delivery compositions. The polymers are particular suitable for formulating amine drugs, such as amphetamine, methylphenidate, rivastigmine, paroxetine and clonidine.

A transdermal drug delivery patch and a method of controlling the drug release of the transdermal drug delivery patch by near-IR are disclosed. The transdermal drug delivery patch comprises a substrate, carriers and drugs. The drugs are encapsulated in the carriers, and the carriers having the drugs are disposed on a surface of the substrate. The carriers are formed of biodegradable polymers, and nano-particles with a photothermal conversion effect are loaded in the carrier. When the carriers are punctured into the skin and the nano-particles in the carrier absorb the near-IR, the near-IR is converted into heat by the nano-particles to melt the carrier and thus releasing the drugs encapsulated in the carrier into the skin. Accordingly, the speed of releasing the drugs encapsulated in the carrier can be controlled accurately by the near-IR.

Botanically derived anti-irritants for prophylactic and therapeutic treatment of adverse skin reactions from application of transdermal or topical drug delivery system, permits the effective administration of a drug from a delivery system in which the drug, of a component of the delivery system comprises a skin irritant; and the delivery systems formed thereby.

Nasal dilators and strips, methods of their manufacture, and methods for improving the breathing of individuals are provided. The strips and dilators include an elongated substrate, with or without a dilating component or portion, having top and bottom surfaces and a pressure-sensitive adhesive disposed on the bottom surface. The dilator is designed to provide a gentle expanding force to the nasal wall tissue when the dilator is adhesively attached to the nose. This invention further includes a cosmetic fragrance, an aromatic medication and/or transdermal medication disposed on the strips or dilators. In order to improve the shelf-life and in-use olfactory effectiveness of such products, fragrance delivery mechanisms are used. Separation of volatile oils and adhesives are also provided to minimize adhesive residue.

Topical drug delivery formulations with optical amounts of vasodilator. Vasodilator chemicals applied topically dilate the blood vessels in the skin tissue, which have been shown to facilitate or inhibit systemic or skin tissue deposition of drug substances. The level of stimulation and/or inhibition has been found to be dependent on the concentration and the identity of the specific vasodilator chemical(s) used as well as the drug molecule(s) to be delivered. This work teaches the need to consider specific formulation requirements when dealing with vasodilator chemicals for the creation of successful delivery vehicles in the transdermal drug delivery system. These requirements for very low concentrations of vasodilators were an unexpected and a surprise finding, in contrast to the concentrations of the vasodilators typically used to elicit an increase in skin blood flow.
