I. Introduction
Modern day healthcare systems are complex networks consisting of several independent entities. That includes the origin point as manufacturer companies and the end user as the drug consumer who is the best priority. In this process, many organizations, transportation modes, and stakeholders such as distributors, producers, wholesalers, drivers, and pharmacists are actively involved in the pharmaceutical supply chain under various situations. While doing this delivery process it has been identified that in public health, the safety of the pharmaceuticals throughout the supply chain is one of the major concerns, which is a collective process. When it is considered deeper on the safety approach, the security threat is the most significant safety violation that is happening in the current drug supply chain. Prevention of counterfeit pharmaceuticals and managing the access privileges to the stakeholders are identified as the major precautions needed for the advanced security approach in the supply chain. The next main safety related violation that can ordinarily happen in the pharmaceutical supply chain is cold chain management with parameter monitoring in the stored environments. Once the drug is purchased a proper mechanism should be there to share the customer feedback with the audience. In the current supply chain, there is no existing customer satisfaction monitoring.
