Integrating Blockchain Technology in Pharmaceutical Supply Chains

Abstract

This paper presents a transformative approach to enhancing transparency, security, and traceability. By utilizing a decentralized ledger system, stakeholders can access real-time data about drug provenance and distribution, thereby increasing consumer confidence and improving regulatory compliance. Existing pharmaceutical supply chains face significant challenges, including counterfeit drugs, lack of visibility, and inefficiencies in tracking products through complex logistics networks. These issues lead to financial losses, compromised patient safety, and regulatory penalties. This study proposes a novel framework, the Pharmaceutical Supply Chain using Blockchain Technology (PSC-BCT), designed to address these existing challenges. The PSC-BCT framework leverages smart contracts, distributed ledgers, and IoT integration to create a secure, transparent, and efficient supply chain ecosystem. This framework enables all participants, from manufacturers to pharmacists, to share and verify transaction data, thereby enhancing accountability and reducing the risk of fraud. The proposed method is utilized to streamline operations, reduce delays, and enhance data integrity within the pharmaceutical supply chain. By ensuring that every transaction is recorded immutably, stakeholders can verify product authenticity and track the drug's journey from production to the end consumer. The findings indicate that the PSC-BCT framework significantly improves supply chain transparency and efficiency while reducing instances of counterfeit drugs. Furthermore, the implementation of blockchain technology fosters trust among stakeholders and enhances compliance with regulatory standards, ultimately leading to improved patient outcomes and safety.
