94 - Formulation Challenges for Biologics & Injectables (S7E4)

This episode tackles the unique challenges encountered when formulating biologics and injectables, particularly regarding sterility and stability. It compares and contrasts the formulation challenges of small molecule drugs versus biologics, highlighting the complexities associated with larger, more fragile biomolecules. The discussion explores the stringent manufacturing processes required for injectables to ensure sterility and prevent contamination. Real-world examples from OPR&D and other sources illustrate these challenges and the innovative solutions employed to overcome them.

Beyond simply dissolving a drug in a solution, formulating injectables requires meticulous attention to detail to ensure patient safety. The episode emphasizes the importance of maintaining stability in biologics, which are prone to degradation and aggregation due to their complex structures. The discussion also delves into the role of buffer salts in maintaining stability and influencing drug solubility. Furthermore, the episode explores the challenges associated with drug delivery, including how to get these large molecules to the right place in the body and how to control their release profile. Finally, the episode touches upon real-world examples of formulation challenges encountered with specific drugs, highlighting the importance of problem-solving and innovation in this field.
