Solubility principles and practices for parenteral drug dosage form development.

Solubilization of poorly water soluble or water insoluble drugs for use in intravenously administered dosage forms is a very formidable task for the parenteral formulation scientist. We have briefly reviewed pertinent literature for parenteral drug solubilization and provided tabular information to assist parenteral formulation scientists in tackling and solving their solubility problems. However, until we can better understand and predict solubility behavior in interactive solvent systems, the why's and how's for parenteral drug solubilization using acceptable (safe and regulatory compliant) approaches will largely remain an empirical effort, leaving great opportunities for scientists to get more involved in this field.
