Particulate drug delivery systems include solid formulation of nanometric & micron size range with modified release profiles. These are either reservoir type or matrix type. One of their most useful features is that they are easy to inject, either into tissue or intravenously. They are also easily adapted to other milieus, for inhalation as a dry powder, or topically in an appropriate vehicle. Salient features - Modulate release rate - Suitable for both soluble & insoluble drugs - Protect active from harsh biological environment - Targeted delivery through ligand-conjugation & modified size/surface properties
