Unlocking the potential of remdesivir: innovative approaches to drug delivery.

Given the recurrent waves of COVID-19 and the emergence of new viral infections, optimizing the potential of remdesivir as an antiviral agent is critical. While several reviews have explored the efficacy of remdesivir, few have comprehensively addressed its challenges, such as the necessity for intravenous infusion, suboptimal lung accumulation, and safety concerns related to its formulation. This review critically examines these challenges while proposing innovative solutions and effective combinations with other antiviral agents and repurposed drugs. By highlighting the role of complex generics, we aim to enhance therapeutic efficacy in ways not previously discussed in existing literature. Furthermore, we address the development of novel drug delivery systems which specifically aim to improve remdesivir's pharmacological profile. By analyzing recent findings, we assess both the successes and limitations of current approaches, providing insights into ongoing challenges and strategies for further optimization. This review uniquely focuses on targeted drug delivery systems and innovative formulations, thereby maximizing remdesivir's therapeutic benefits and broadening its application in combating emerging viral threats. In doing so, we fill a critical gap in literature, offering a comprehensive overview that informs future research and clinical strategies.
