  1. 1. Prolonged Drug Release from Gels, using Catanionic Mixtures

    Författare :Tobias Bramer; Katarina Edsman; Per Hansson; Stefan Ulvenlund; Uppsala universitet; []
    Nyckelord :Pharmaceutics; gel; catanionic; vesicle; micelle; controlled release; diffusion; surfactant; drug delivery; Galenisk farmaci;

    Sammanfattning : The use of catanionic drug-surfactant mixtures was proven to be an efficient novel method of obtaining prolonged drug release from gels. It was shown that various commonly used drug compounds are able to form catanionic mixtures together with oppositely charged surfactants. LÄS MER

    Sammanfattning : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.
