  • Publication number: 20150182745
    Abstract: A device based on iontophoresis and intended for transdermal dosing of an active agent, said device comprising a pair of electrodes (11,12), which can be connected to a direct-current source, and two chambers (13, 14), separated from each other, the first chamber (13) containing the active agent, each chamber having a porous membrane (15, 16) on the side facing the individual's skin, and the first chamber (13) being divided in two sections (13a, 13b) in such a manner that the first chamber section (13a) is in contact with the electrode (11) and the second chamber section (13b) is in contact with the membrane (15) coming into contact with an individual's skin, wherein between the chamber sections (13a and 13b) is a membrane (18) selectively permeable either to cations or to anions, the first chamber section (13a) containing an electrolyte and the second chamber section (13b) containing the ionic active agent, bound to a ion exchanger therein, which in turn preferably comprises fibres and ion exchanging grou

  • Publication number: 20120135081
    Abstract: In the field of drug or nutrient administration novel particles and formulations thereof are provided. Said particles each have a core comprising active agent and at least partial coating comprising proteins, selected from hydrophobins. Preferable hydrophobins belong to class I or class II. Said particles exhibit enhanced characteristics, for example dispersibility or solubility. Here is also disclosed two methods for producing said particles in nanoscale, of which one utilizes precipitating and another wet milling.

  • Publication number: 20080165354
    Abstract: The invention concerns a method and apparatus for monitoring physical and chemical properties of a solid sample during a dissolution process, the sample comprising at least one soluble component. In the method, the solid sample is brought into contact with dissolution medium for producing a solution and a solid residue of the solid sample, the solution is analyzed for determining the concentration of the soluble component during the dissolution process. Simultaneously with analyzing the solution, the atom- or molecule-scale physical or chemical composition of the solid residue is analyzed. The invention provides a new method for studying phenomena taking place in the solid residue during a dissolution process.
