  • Topical nanoparticulate spironolactone formulation
    Publication number: 20060067892
    Abstract: The invention relates to a topical nanoparticulate spironolactone formulation comprising nanoparticles having a mean diameter, measured by a photon correlation spectroscopy, in the range of from about 300 nm to about 900 nm. The nanoparticles are incorporated into a crystalline network system comprising a dispersion of solid crystals of polar lipids, said lipids exposing their hydrophilic side outwards and their hydrophobic side inwards towards the spironolactone nanoparticles.

  • Encapsulation of nanosuspensions in liposomes and microspheres
    Publication number: 20030096000
    Abstract: Sustained release of hydrophobic agents may be achieved by incorporation of the agents into liposomes and microspheres. This is achieved by use of a nanosuspension comprising the hydrophobic agent. The nanosuspension may be used as the aqueous solution in the formation of the liposomes and microspheres.
