The production, distribution, and dispensing of pharmaceuticals—from raw materials to the final patient—are handled by a complicated web of organizations known as the pharmaceutical supply chain. Numerous parties are involved, including as pharmacies, healthcare professionals, wholesalers, distributors, and manufacturers. Maintaining patient safety, regulatory compliance, and the availability and quality of pharmaceuticals are all dependent on the supply chain. Purchasing raw materials from vendors is the first step in the process. Next are the stages of product manufacture and packing, delivery to pharmacies and hospitals, transportation to distribution centers, storage, and inventory management. Since there are many chances for mistakes, adulteration, or counterfeiting along the supply chain, it is crucial to have strong quality control procedures and real-time monitoring systems in place to guarantee the integrity of the pharmaceutical goods.
