The primary focus of this research is to develop an in vitro method that uses an appropriate formulation:blood ratio and contact time to evaluate the degree of hemolysis occurring after an intravenous injection. The effects of both the formulation composition and the formulation:blood contact time on hemolysis are given in Chapters I-IV. Since hemolysis is shown to increase as either the formulation:blood ratio and/or the contact time increases for various pharmaceutical vehicles, a small formulation:blood ratio and short contact time must be selected to determine the degree of hemolysis occurring as the formulation is rapidly diluted by the blood after an intravenous injection. Using a formulation:blood ratio of 0.1 and a contact time of 1 second, a dynamic method has been developed to evaluate intravascular hemolysis. The ability of this method to accurately evaluate hemolysis occurring after an injection is determined by comparing hemolysis data generated with this dynamic method to in vivo hemolysis data obtained from the literature. The results of this comparison are given in chapter V. The in vitro hemolysis data are shown to be in agreement with in vivo hemolysis data.
