The current use of high speed machinery in the pharmaceutical industry dictates that the pharmaceutical scientist must be cognizant of the physical and chemical properties of drugs and other adjuvants used in pharmaceutical dosage forms. Our research has focused on controlled release technologies and polymeric drug delivery systems. Our current research emphasis is concerned with the microencapsulation of peptides and proteins, aqueous film coating of beads, tablets and soft gelatin capsules, hot-melt extrusion, and compaction properties of tablets and extruded beads. Analytical techniques including HPLC, GPC, DSC and X-ray diffraction are routinely used in our investigations to characterize stability and other important properties of raw materials and the finished dosage form.
