A method of administering a pharmaceutical agent to the circulatory system through the skin of a mammal may include the steps of loading a pharmaceutical agent in a transdermal patch, applying the transdermal patch to the skin of the mammal and releasing the pharmaceutical agent into the circulatory system at a rate of at least 0.001 micrograms per hour up to 50.0 micrograms per hour per kilogram of bodyweight of the mammal. The drug delivery system may comprise a transdermal patch loaded with the pharmaceutical agent. The patch may include a porous membrane and an outer impermeable cover defining a cavity therebetween. A plurality of drug delivery layers may be disposed between the porous membrane and the impermeable cover. A lipophilic/hydrophilic suspension may be disposed between the drug delivery layers.

The present invention relates to a method for producing a drug delivery system. The method comprises the steps of screen-printing a base paste, and curing the base paste. Furthermore, the method comprises the steps of screen-printing a first paste separate to the base paste, and curing the first paste.

A composition comprising an oxidoreductase enzyme and a substrate for the enzyme for use in treating or preventing biofilm formation by a population of pathogenic bacteria. The composition can be incorporated into a wound dressing for use in promoting wound healing.

The present invention relates to a drug delivery system, in particular for a controlled administration of one or more active pharmaceutical ingredients to a body, and further in particular for oral administration of one or more active pharmaceutical ingredients to a body. The system thereby comprises a base component soluble in body fluids and a separate first component soluble in body fluids. The first component thereby comprises a therapeutically effective amount of a first active pharmaceutical ingredient.

The present invention relates to large scale manufacture of nanoscale microsheets for use in applications such as wound healing or modification of a biological or medical surface.

Methods for producing systems for the transdermal or permucosal administration of active substances and particularly transdermal therapeutic systems (TTS), wherein the active substance depots thereof have a shape that deviates from a rectangular design.

The invention relates to a method of treating pain in a patient by applying a transdermal therapeutic system for the transdermal administration of buprenorphine for 7 days on the skin of a patient, said transdermal therapeutic system comprising a buprenorphine-containing self-adhesive layer structure comprising A) a buprenorphine-impermeable backing layer, and B) a buprenorphine-containing matrix layer on said buprenorphine-impermeable backing layer, the matrix layer comprising a) a polymer base, b) buprenorphine, and c) a carboxylic acid selected from the group consisting of oleic acid, linoleic acid, linolenic acid, levulinic acid and mixtures thereof, in an amount sufficient so that said buprenorphine is solubilized therein to form a mixture, and the carboxylic acid buprenorphine mixture forms dispersed deposits in the polymer base, and C) a skin contact layer on said buprenorphine-containing matrix layer comprising a polymer-based pressure-sensitive adhesive, and optionally wherein the buprenorphine-containing self-adhesive layer structure contains said buprenorphine in an amount of less than 0.8 mg/cm2 buprenorphine base or an equimolar amount of a pharmaceutically acceptable salt thereof.

The invention relates to a transdermal therapeutic system on the basis of polysiloxane which contains microreservoirs filled with an active substance and one ambiphilic solvent.

Transdermal therapeutic system and method of using the same for safely treating hypocholinergic disorders of the central nervous system such as Alzheimer type dementia. The transdermal therapeutic system comprises oxybutynin in combination with a cholinergic receptor agonist (CRA) such as xanomeline.

The present invention provides a microneedle patch which can solve the problem that microneedle production is difficult and requires high accuracy, the problem that time and mental burdens on a health professional and a patient are large, and the problem caused by compounding a plurality of drugs. The microneedle patch comprises a large number of drug-carrying microprojections 4 erected on one support sheet, each microprojection 4 having a drug layer 5 soluble in vivo at its top part and having an intermediate layer 6 under the drug layer 5, the intermediate layer 6 containing a polymeric substance for adhesion of the drug layer 5 to the support sheet, the drug layer 5 at the top part of the microprojection 4 containing a single drug, the microprojections 4 holding difference types of drugs being arranged together on the support sheet 2.
