    摘要: A process for preparing microspheres using very cold temperatures to freeze polymer-biologically active agent mixtures into polymeric microspheres with very high retention of biological activity and material. Polymer is dissolved in a solvent together with an active agent that can be either dissolved in the solvent or dispersed in the solvent in the form of microparticles. The polymer/active agent mixture is atomized into a vessel containing a liquid non-solvent, alone or frozen and overlayed with a liquified gas, at a temperature below the freezing point of the polymer/active agent solution. The cold liquified gas or liquid immediately freezes the polymer droplets. As the droplets and non-solvent for the polymer is warmed, the solvent in the droplets thaws and is extracted into the non-solvent, resulting in hardened microspheres.

    摘要: Pharmaceutical proton pump inhibitor (PPI) medications and methods are disclosed for preventing and/or treating gastrointestinal disorders characterized by abnormalities in gastric acid secretion at anytime of the day or night without the need for food effect or to be taken with food. The medications comprise a PPI and a cholinergic agonist for inducing rapid onset of PPI action, for increasing the duration of PPI efficacy and for optimizing clinical PPI effectiveness that may be administered at any time of the day or night without food or on an empty stomach, and possibly on an as-needed or on demand basis. In carrying out the methods, a PPI and cholinergic agonist may be administered together as a single unitary dose in the form of a liquid or solid, or administered together, but separately as either liquids or solids or a combination thereof. Preferably, an oral solid dosage form of the present invention allows for release of a proton pump inhibitor at a pH of about 5 or higher, e.g., pH about 5.5, 6, 6.5 or 7, followed by release of a cholinergic agonist within between about 10 minutes and about 60 minutes, preferably within about 15 minutes and about 30 minutes, after release of the proton pump inhibitor from the dosage form, so that it can be administered at any time of the day or night independent of food or food effect. It is believed that the methods and compositions of the present invention will increase the duration of PPI efficacy by between at least about 5 fold and about 10 fold or even about 20 fold, as compared to the duration of PPI efficacy derived from current PPI dosage forms administered alone and without food or a food effect. Kits comprising a PPI, a cholinergic agonist and optionally an antacid are disclosed, such as kits containing each drug in conventional and commercially available dry or liquid dosage forms for simultaneous or concomitant administration or in dry dosage forms to provide for the easy preparation of a liquid composition from the dry dosage forms. These new medications and methods will simplify the traditional continuous PPI regimen and improve patient compliance.

    摘要: Small diameter particles of biologically active molecules are produced by atomizing solutions of the molecules through a nozzle into very cold liquified gases, which immediately freeze the atomized droplets. The resulting frozen particles having diameters of approximately 10 to 90 micrometers are lyophilized to produce porous particles, suspended in a non-solvent for the molecules, and exposed to ultrasonic energy or homogenization to produce particles having diameters of 0.1 to 10 micrometers with greater than 70 to 95% of the initial biological activity of the molecules in solution.

    摘要: A method and apparatus for non-invasive extraction and/or detection of chemicals such as heavy metals, drugs such as cocaine and analytes such as blood glucose has been developed. A patch or hydrogel containing a reagent such as N-methyl pyrrole, or a similar compound, is used to extract the chemical or analyte to be measured through the skin or hair. This method is most useful for detecting analytes which are generally present in relatively constant blood concentrations. The method is particularly useful for the detection of heavy metals such as lead, lithium, copper, iron, and has been demonstrated to be useful with drugs such as cocaine and acetominaphen, and metabolic analytes like blood glucose. In the preferred embodiment, the method involves the use of the water miscible solvent N-methyl pyrrolidone (NMP) in an aqueous solution which is incorporated into an adsorbent pad or hydrogel. This adsorbent pad is placed on the skin for a defined time period, removed and then analyzed for the substance of interest. An analytical method can also be incorporated as part of the adsorbent pad in order to conduct both the extraction of the chemical of interest and the assay in situ. Examples demonstrating the very broad range of materials which can be extracted. Comparative examples demonstrate that the same results cannot be obtained using other reagents such as dimethylsulfoxide (DMSO).

    摘要: Compositions and methods for repelling an animal from an area or object are described. The compositions include an animal repellent dissolved or dispersed in a polymer where the repellent is released from the polymer over a period of time in an amount effective to repel an animal from the area. Capture of the repellent in the polymeric matrix allows for concentration of the repellent in an easily movable or removable device. Moreover, the repellent is not diluted by contact with water. The composition is provided in a usable form as a film, a sheet, a shaped article, pellets, or microparticles. The method for repelling an animal from an area or object includes preparing a device incorporating the above compositions and placing the device in an area or near or on an object desired to be protected. The devices can be manufactured by solvent evaporation, solvent removal, coextrusion, spray drying, and hot melt encapsulation. In a preferred embodiment the polymer is ethylene vinyl acetate copolymer and the repellent is methyl nonyl ketone or animal predator urine.
