Platform technology in pharmaceutical development refers to standardized methods, tools, and processes that accelerate drug discovery, formulation, and manufacturing for multiple products. For B.Pharm students, mastering platform approaches—such as biologics and small-molecule platforms, lipid nanoparticle (LNP) and mRNA platforms, modular manufacturing, continuous processing, process analytical technology (PAT), and Quality by Design (QbD)—is vital for effective drug development. Platform strategies enhance scalability, reproducibility, regulatory compliance, and cost-efficiency across preclinical and clinical stages.
