ABSTRACT
The successful development and manufacture of pharmaceutical dispersions for parenteral administration relies on accurate analysis and characterization of these products. Applications of injectable emulsions, liposomes, and suspensions share one common problem: a few oversize particles in any of these submicron colloidal systems could cost the loss of hundreds of thousands of dollars and, even more importantly, more loss of life in the case of intravenous (i.v) delivery (1). It is imperative that high-quality injectable dispersed systems be developed and maintained, and that adequate,
consistent, and comprehensive tests are available to ensure product quality and safety.
