  • Publication number: 20190231707
    Abstract: Systems and methods are provided herein for transdermal delivery of an opioid. The opioids can be delivered in a decreasing dose (dose-tapering) manner to minimize withdrawal symptoms and abuse. The systems are also designed to limit a person besides the patient from receiving the drug with the transdermal delivery device. The systems can also include abuse-deterrence features that limit the ability of a patient or unauthorized user from tampering with the device to receive the active ingredient. Novel transdermal drug delivery formulations are also provided that include an opioid agonist or partial agonist and opioid antagonist which prevent the abuse of formulation.

    Abstract: A method of purifying a plurality of metal oxide particles produced from a synthesis process is disclosed. The method comprises the step of washing a plurality of metal oxide particles in a first solvent composition comprising of at least one aliphatic ether, and at least one flocculant. In one embodiment, the plurality of metal oxide particles are iron oxide particles produced from a thermal decomposition synthesis process between an iron-oleate complex and oleic acid in 1-octadecene, wherein the first solvent composition comprises a 1:1 (vol/vol) ratio of an aliphatic ether in the form of diethyl ether and a flocculant in the form of methanol. The washed iron oxide particles are further washed in a second solvent composition comprising a 1:1 (vol/vol) ratio of hexane and ethanol, and then finally dispersed in hexane.

  • Patent number: 9134079
    Abstract: The invention provides apparatuses and techniques for controlling flow between a manifold and two or more connecting microchannels. Flow between plural connecting microchannels, that share a common manifold, can be made more uniform by the use of flow straighteners and distributors that equalize flow in connecting channels. Alternatively, flow can be made more uniform by sections of narrowed diameter within the channels. Methods of making apparatus and methods of conducting unit operations in connecting channels are also described.
