Counterfeit medications are currently one of the biggest issues in pharmacology. According to a research from the Health Research Funding organization, between 10–30% of pharmaceuticals in underdeveloped nations are counterfeit. The primary problem is not in counterfeiting per such, but rather in the fact that these pharmaceuticals have distinct adverse consequences on human health when compared to regular drugs. The WHO estimates that over 30% of all medications sold in Latin America, Asia, and Africa are fake. This is the main issue facing the entire world, and things become worse in underdeveloped nations where one in ten medications are either counterfeit or do not adhere to drug standards. It is becoming increasingly challenging to standardize drug safety due to the growth of online pharmacies. It is challenging to identify fakes. The safety of the pharmaceutical supply chain is becoming a serious public health concern, a process that affects all of us. In this work, we present a new approach to medication supply chain management that handles safe drug supply chain data using Hyperledger Fabric, a blockchain-based platform. By implementing drug record transactions on a blockchain, a drug supply chain and smart healthcare ecosystem may be constructed. The suggested method addresses this issue. To allow for time-limited access to patient health information and electronic prescription records, a smart contract has been introduced.
