The purpose of this course is to introduce pharmacy students to the fundamentals of principle, practices and technologies involved in pharmaceutical product developmentand its exploration from laboratory to global market. The course demonstrate theinterrelationships between laboratory scaling of pharmaceutical products, pilot plantsand commercial level manufacturing of the various dosage forms. The course exploresthe basic processes of energy transfer, mixing, drying, comminution, evaporation andcompaction.
