Pharmaceutical supply chain is a complex network of interconnected organizations and processes involved in the discovery, development, manufacturing, distribution, and dispensing of pharmaceutical products. As a distinct field of academic inquiry and management practice, it investigates the strategic and operational management of material, information, and financial flows across this network, from raw material sourcing to delivery to the final patient or healthcare provider. Key characteristics include stringent regulatory compliance, specialized logistics such as cold chain requirements, critical public health implications, and inherent risks related to product quality, security, and accessibility. Its significance lies in ensuring the efficient, safe, and equitable delivery of essential medicines globally, impacting public health outcomes and economic stability through optimized operations and risk mitigation.
