Traditional pharmaceutical supply chains suffer from inefficiencies, limited transparency, and fragmented data management, which create significant opportunities for the entry of counterfeit and substandard drugs. These challenges compromise patient safety, regulatory compliance, and trust among stakeholders. To address these issues, this paper proposes a blockchain-enabled secure data sharing framework that ensures end-to-end traceability and integrity across the drug supply chain and delivery lifecycle. The proposed solution leverages a decentralized distributed ledger (DLT) combined with smart contracts to securely record, verify, and automate transactions among manufacturers, distributors, pharmacies, and healthcare providers. The framework is implemented using Hyperledger Fabric, which is well suited for private, permissioned enterprise environments requiring controlled access and high throughput. Smart contracts enforce automated compliance checks, ownership transfer, and delivery validation in real time. The proposed approach enhances supply chain security, enables real-time tracking of pharmaceutical products, reduces counterfeit drug circulation, and improves operational transparency. Overall, the framework strengthens trust, accountability, and efficiency in modern drug supply chain and delivery systems.
