Course Name : PHARMACEUTICAL FORMULATION DEVELOPMENT

Code(Credit) : CUTM2001(4-0-0)

Course Objectives

To impart knowledge and skills necessary to train the students on par with the routine of Industrial activities in R&D and F&D

Learning Outcomes

On completion of this course it is expected that students will be able to understand-

  • The scheduled activities in a Pharmaceutical firm.
  • The pre formulation studies of pilot batches of pharmaceutical industry.
  • The significance of dissolution and product stability.
  • How to apply the knowledge and skills on drug development

Course Syllabus

Module-1: 

Preformulation Studies: Molecular optimization of APIs (drug substances), crystal morphology and variations, powder flow, structure modification, drug-excipient compatibility studies, methods of determination.

Module-2:

Formulation Additives: Study of different formulation additives, factors influencing their incorporation, role of formulation development and processing, new developments in excipient science. Design of experiments – factorial design for product and process development.

Module-3:

Solubility: Importance, experimental determination, phase- solubility analysis, pH-solubility profile, solubility techniques to improve solubility and utilization of analytical methods – cosolvency, salt formation, complexation, solid dispersion, micellar solubilization and hydrotropy.

Module-4:

Dissolution: Theories, mechanisms of dissolution, in-vitro dissolution testing models– sink and non-sink. Factors influencing dissolution and intrinsic dissolution studies. Dissolution test apparatus – designs, dissolution testing for conventional and controlled release products. Data handling and correction factor. Biorelevant media, in-vitro and in-vivo correlations, levels of correlations.

Module-5:

Product Stability: Degradation kinetics, mechanisms, stability testing of drugs and pharmaceuticals, factors influencing-media effects and pH effects, accelerated stability studies, interpretation of kinetic data (API & tablets). Solid state stability and shelf life assignment. Stability protocols, reports and ICH guidelines.
