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.
