The pharmaceutical supply chain is critical to ensuring the availability of life-saving medications and healthcare products. However, it is highly vulnerable to disruptions, including natural disasters, economic and political instabilities, supply chain vulnerabilities, and technological failures. This review explores strategies for enhancing resilience within the pharmaceutical supply chain, focusing on risk management, supplier diversification, inventory management, and the integration of advanced technologies such as IoT, AI, and block chain. Case studies, including the impact of the COVID-19 pandemic, natural disasters like Hurricane Maria, and geopolitical challenges like the US-China trade war, are analyzed to extract valuable lessons and strategies that proved effective in maintaining supply chain continuity. The review also looks ahead to future trends, emphasizing the importance of digital transformation, sustainability, and ethical sourcing in building a more robust and adaptable pharmaceutical supply chain. The findings underscore the need for proactive disruption management, strategic diversification, and sustainable practices to ensure the uninterrupted delivery of essential healthcare products.
