Abstract: Described herein are methods for quantitatively determining the amount of the amphetamine-related compound identified herein as amphetamine carbamate (amphetammonium-amphetacarbamate) present in a drug-containing polymer matrix comprising amphetamine, and for assessing a drug-containing polymer matrix comprising amphetamine. The methods may comprise converting any amphetacarbamate present into reaction products comprising carbonate, quantifying the amount of carbonate, and quantifying the amphetacarbamate originally present from the quantified amount of carbonate.
Abstract: Described herein are the amphetamine-related compounds amphetamine carbamate (amphetammonium-amphetacarbamate) and amphetacarbamate, methods of making them, methods for detecting or quantitatively determining the amount of amphetacarbamate or amphetamine carbamate in a compositions, and ion chromatography columns useful in such methods.
Abstract: Described are methods for reducing the formation of amphetamine carbamate and amphetacarbamate in transdermal amphetamine compositions, compositions with low levels of amphetacarbamate, and methods using such compositions for transdermal delivery of amphetamine.

Abstract: Described are transdermal drug delivery compositions comprising amphetamine, methods of making them and therapeutic methods using them. The compositions are provided in a flexible, finite form (e.g. “patch”-type systems) and comprise a polymer matrix that includes amphetamine and an acrylic block copolymer.
Abstract: Stretchable, occlusive backing layers for transdermal drug delivery systems are disclosed, that maintain occlusivity after stretching. The backing layers are comprised of a stretchable backing material provided with an occlusive coating comprising a styrene-isoprene-styrene block copolymer and tackifier. Also described are transdermal drug delivery systems having such backing layers, including transdermal drug delivery systems for non-steroidal anti-inflammatory drugs (NSAIDs), and methods of making and using such backing layers and transdermal drug delivery systems.
Abstract: Described are microneedle devices comprising an electron beam crosslinked or photocrosslinked polymer material, and methods of making and using them, such as for drug delivery or sampling biological fluids.
Abstract: Described are transdermal drug delivery systems for the transdermal administration of tertiary amine drugs, such as rivastigmine, fentanyl or rotigotine, comprising a polymer matrix comprising a free base form of the drug and at least one carboxyl group-containing compound. In some embodiments, the systems include a rate-controlling membrane and a skin-contacting face adhesive apart from the polymer matrix.
