RESUMEN
Pharmaceutical development is a highly regulated industry through numerous worldwide guidance, laws, and regulations. Issues related to the safety of pharmaceutical products have been the most common cause of withdrawals from the market, as well as restrictions on distribution and limitations on labeling. Collaboration (hereafter referred to as partnership) between pharmaceutical companies in drug development has been recognized as critically significant to maximize the efficiency of drug development. In general, pharmaceutical companies might benefit from partnering in conducting pharmacovigilance (PV) activities, resulting in enhanced safety monitoring, improved clinical outcomes, and support of optimal benefit-risk assessment. However, some challenges exist. Differences between partners in strategy, culture, and processes can impact the harmonization of safety practices and decision-making processes, necessitating open communications and consensus-building to effectively address safety concerns. Both successful and unsuccessful partnership attempts within the pharmaceutical industry provide valuable business cases and lessons for the future. This paper sheds light on some of the critical aspects of PV in partnerships within the pharmaceutical industry. It addresses issues of the benefits and risks of partnerships, regulatory/legal expectations, and best practices for safety teams' integration.
