The pharmaceutical supply chain is a complex network of entities involved in the manufacture, distribution, and dispensing of medications from raw materials to the end consumer. It involves various stakeholders, including manufacturers, wholesalers, distributors, pharmacies, and healthcare providers. The supply chain is critical to ensuring the quality and availability of medications, as well as maintaining patient safety and adherence to regulatory requirements. The process begins with the sourcing of raw materials from suppliers, followed by manufacturing and packaging of finished products, transportation to distribution centers, storage and inventory management, and finally delivery to pharmacies and hospitals. Throughout the supply chain, there are numerous opportunities for errors, adulteration, or counterfeiting, making it essential to implement robust quality control measures and real-time monitoring systems to ensure the integrity of the pharmaceutical products.
