Nanocrystals / nanosuspensions of drugs are sub-micron colloidal dispersions of pure drug crystal particles in nanometer size, which are stabilized by surfactants.
High mass to volume drug loading
Reduced administration volume which is crucial for low-volume intramuscular and ophthalmic applications
Improved drug stability due to increased resistance to hydrolysis and oxidation by solid state drug crystal form
Drug depot for prolonged release profile thereby to achieve long-acting therapeutic effect
