Aplicación de Blockchain a la cadena de suministros de medicamentos:  una revisión bibliométrica

The drug supply chain is a critical process that involves multiple stakeholders, including pharmaceutical laboratories, logistics companies, pharmacies and patients. Distributed ledger technology such as blockchain can improve security and transparency in the drug supply chain, providing a decentralized and secure record of all transactions made in the process. Also, it allows defining mechanisms that help mitigate the falsification and manipulation of medicines, facilitating public health surveillance and providing a reliable environment for the acquisition and consumption of medicines. On the other hand, the implementation of blockchain tends to guarantee the security and privacy of the data associated with the actors in the supply chain, but one of its greatest challenges faces the limitations of interoperability, that is, the ability for different Blockchains can communicate with each other and share information. Finally, this article presents a bibliometric review of indexed publications in the period of time between 2018 and 2023, characterizing the line of publications in this area, with indicators associated with authors, publication sources and trends in keywords and topics associated.
