Blockchain Solution for Drug Recall Management


Our client is a US-based multinational pharmaceutical company that manufactures and sells medicinal formulations and active ingredients across 40 countries.




Drug recalls affect hundreds of pharmaceutical companies every year impacting sales, customer relationships, and supply chain operations. The existing centralized models do not address issues surrounding traceability and recall. Products in the pharmaceutical supply chain move through multiple intermediaries before reaching the consumer, making the recall process complex and cumbersome. Emerging technologies, such as blockchain, offers pharmaceutical companies the opportunity to drive efficiency across the supply chain. In an effort to create a transparent environment for information access, a leading pharmaceutical company wanted to implement a blockchain solution to ensure accountability at the distributor level.

Business Requirement

Our client wanted a system that notifies distributors when a particular product or batch/lot number is slated for recall. With distributors spread across geographies, there was a need to augment the process with an effective recall strategy.

QBurst Solution

Our solution is a fully decoupled, microservices-based architecture on Ethereum blockchain involving smart contracts. The parties involved in the supply chain log their data into a common blockchain. The manufacturer logs the production date and time of each batch and unit. Every time a batch of drugs is added, it is written to the Ethereum blockchain. The blockchain emits events for predefined scenarios such as potential contamination, mislabeling, or manufacturing defects. This way, any client software on the distributor side, irrespective of technology, can listen to these events and take appropriate action.
