The pharmacovigilance system master file (PSMF) is a detailed description of the pharmacovigilance system used by the marketing authorisation holder for their authorised medicinal products. The PSMF is intended to be a live, custom-made document that accurately reflects the pharmacovigilance system put in place for a given product. It is expected to contain meticulous detail so that the marketing authorisation holder's compliance with current good pharmacovigilance practices guidelines can be assessed. This article focuses on the feedback provided by the inspectors during their assessment of the PMSF with an emphasis on areas for improvement.
