Abstract
Particles of a substantially water insoluble biologically active substance, such as Cyclosporin, are loaded with a charged glyceryl ester as an electrostatic stabilizer which imparts to the particles a zeta potential and having an active substance:stabilizer weight ratio of 1:1 to 400:1 and an average particle diameter of 1 nanometer to 10 micrometers. Compositions having such particles are found to be useful delivery systems.
