Top ten considerations in the development of parenteral emulsions.

The development of parenteral emulsions continues to play an important role in the formulation and delivery of many drugs. In addition to solubilization and stabilization applications, appropriately designed parenteral emulsions are effective delivery systems for sustained release and targeting of drugs. Control of the strict requirements of globule size and surface charge is important in the design and ultimate stability of the formulation. This review highlights the important issues and suggests strategies to assist the scientist in the development, manufacture and stability of this essential dosage form.
