Preparing regulatory documents for a new drug application (herbal) is a critical skill for B. Pharm students. This introduction explains the structure and content of herbal NDA dossiers, including phytochemical characterization, quality control, Good Manufacturing Practice (GMP) documentation, preclinical safety data, clinical trial protocols, stability studies, efficacy and safety evidence, labeling, and pharmacovigilance plans. Understanding regulatory guidelines such as CTD/ICH and WHO herbal dossier formats, submission checklists, and dossier modules helps students compile complete and compliant submissions. Emphasis on documentation standards, validation records, batch release criteria, and risk assessment prepares graduates for roles in regulatory affairs, quality assurance, and herbal drug development.
