Counterfeit drugs pose a significant risk to patient safety. By implementing blockchain, each pharmaceutical product can be assigned a unique identifier that is recorded on the blockchain. Patients, healthcare providers, and regulators can verify the authenticity and origin of drugs instantly, reducing the chances of counterfeit products entering the market.
Enhanced Transparency
Blockchain provides end-to-end transparency in the drug supply chain. Each transaction, from manufacturing to distribution, is recorded on the blockchain, making it easier to track and trace the movement of drugs. This transparency can help identify inefficiencies, reduce wastage, and improve the overall supply chain management.
Regulatory Compliance
Pharmaceutical companies are subject to strict regulatory requirements. Blockchain can streamline compliance by providing a tamper-proof record of every step in the drug production and distribution process. This ensures that companies can easily demonstrate adherence to regulations, saving time and resources during audits.
