An iontophoretic patch for transdermal delivery of biologically active agents includes at least two electrodes in contact with at least two hydrogel reservoirs. At least one of the hydrogel reservoirs carries at least one active agent and, in use of the iontophoretic patch, is disposed on a user's skin and delivers at least one active agent into the skin. The patch includes a control unit to generate a stimulation pattern having stimulation parameters delivered to stimuli locations on the skin. A stimulation unit generates a time sequence of pulses from the stimulation parameters generated by the control unit. The patch further includes a demultiplexing unit configured to perform independent spatio-temporal distribution of the electrical pulses in the time sequence of pulses to at least one electrode; at least one optical sensing system, for continuously measuring an amount of the active agent in the hydrogel reservoir; and a feedback unit.

The invention relates to a medical product for a fastening duration of at least 7 days having good skin compatibility. The medical product includes a central adhesive compartment (3) and an over-patch. The over-patch is free of active ingredients and is formed from a water-vapor-permeable back layer (1) and an adhesive polymer layer (2) that is free of active ingredients. The invention further relates to a method for the production of the foregoing medical product, and to kits of parts containing laminates of layers 1 and 2.

The present invention relates to transdermal devices comprising prodrugs of anti-pyretic, analgesic, or anti-inflammatory molecules, methods of making such devices, and methods of use thereof for treating, preventing, minimizing, and/or diminishing fever or pain.

A method for creating a consolidated compound for delivering an immunomodulatory and imiquimod to a patient, comprising diluting immunomodulator extract to a desired dilution by transferring a desired quantity of the concentrated immunomodulator to an associated sterile container, the associated sterile container having a defined volume of diluted immunomodulator after dilution thereof, providing a viscous encapsulation material, selecting a prescribed amount of concentrated immunomodulator, the prescribed amount defined as that amount of the diluted immunomodulator extract required to provide a number of doses equal to the number of dispensable increments from the container containing the viscous encapsulation material, introducing the selected amount of each of the diluted immunomodulator extract into the viscous encapsulation material, introducing an amount of imiquimod into the viscous encapsulation material, and mixing the introduced amount of each of the diluted immunomodulator extracts and the introduced amount of imiquimod with the viscous encapsulating material.

Molecular hydrogen has been shown to have cosmetic and medicinal benefits. However, delivery methods have been ineffective in aiding the body in receiving and absorbing the hydrogen. This device has a dry chemical separated from a solution. Both the dry chemical and the solution are housed in a container. The container has a hydrogen impermeable top outer layer and a hydrogen permeable bottom layer. Once initiated, a determined and controlled chemical reaction generates molecular hydrogen within the container. The hydrogen then exits the device through the hydrogen permeable side of the device that is facing the skin. The device carries a low risk of toxicity while providing cosmetic and medicinal advantages.

The invention relates to a transdermal therapeutic system for the controlled release of water-soluble pharmaceutical active ingredients from an aqueous phase, comprising an occlusive back layer, a central device facing the skin for releasing the agent, an adhesive layer concentrically surrounding the dispensing device and a removable protective film. Said device is made from a stationary solid phase and a liquid phase containing the active ingredient in aqueous solution, the solid phase being formed from a solid with a fleecy or spongy structure.

The present disclosure provides a transdermal delivery systems for delivering donepezil free base to patients suffering from central nervous system disorders including dementia and Alzheimer's. The transdermal delivery systems can have a separating layer having at least one surface with a surface energy of at least 40 Dynes, sodium bicarbonate particles in the drug matrix layer where the sodium bicarbonate particles have a D90 particle size of from 0.1 μm to 1000 μm, or a combination thereof.

There is provided a plastic material comprising at least one cannabinoid embedded within a structural polymer, wherein the plastic material is formulated to exude the at least one cannabinoid through an outer surface of the plastic material at a therapeutically effective rate for a period of at least a week or at least a month. The plastic material may comprise a liquid-absorbent material embedded within the structural polymer and a carrier oil absorbed into the liquid-absorbent material, wherein at least one cannabinoid is dissolved in the carrier oil.

A method for delivering a therapeutic agent to a subject from a transdermal delivery system is described, where the therapeutic agent (i) has a half-life in the blood when delivered orally of greater than about 48 hours and (ii) is for the treatment of a chronic condition. The transdermal delivery system achieves transdermal delivery of the therapeutic agent at steady state that is bioequivalent to administration of the therapeutic agent orally, wherein bioequivalency is established by (a) a 90% confidence interval of the relative mean Cmax and AUC of the therapeutic agent administered from the transdermal delivery system and via oral delivery between 0.70 and 1.43 or between 0.80 and 1.25, or (b) a 90% confidence interval of the ratios for AUC and Cmax of the therapeutic agent administered from the transdermal delivery system and via oral delivery between 0.70 and 1.43 or between 0.80 and 1.25.

The present invention provides compositions of GHK-Cu/copper tripeptide to avoid first pass metabolism including transdermal patch compositions. The GHK-Cu/copper tripeptide is preferably in the form of a gel reservoir having polymer and one or more penetration enhancers. The transdermal compositions release GHK-Cu/copper tripeptide in various release patterns to allow 1-7 times delivery of GHK-Cu/copper tripeptide in a week. The transdermal compositions instantly achieve steady state in rats and the concentration is sustained over at least 12 hrs, preferably over 24 hrs.
