  • Manufacturing process of microcapsules for sustained release of water soluble peptides
    Patent number: 6534094
    Abstract: A process for the manufacturing of microcapsules for sustained release of water soluble peptides, with adjustable release periods of between 1 to 18 weeks. The microcapsule wall are made of a biodegradable polymer. The process is based on the formation of an intermediate complex water/oil/water emulsion. By evaporating the solvent in the emulsion by pressure reduction the microcapsules consolidate, retaining the active peptides in the polymeric matrix. The process produces the complex emulsion in a two mixer, continuous operation. In the first mixer a water/oil emulsion is formed and it is used to form the complex emulsion in the second mixer. By operating in a continuous manner, the process overcome the problems found in existing processes regarding particle size distribution, material losses and process control, among others.
