Smart contracts as a tool for increasing efficiency in the pharmaceutical supply chain

The pharmaceutical industry is one of the key sectors of the economy. It is estimated that in 2022, its global value exceeded 1.3 trillion dollars. In Poland, the pharmaceutical market is worth approximately 37 billion zloty.

The efficient operation of supply chains is a crucial element in the pharmaceutical sector. These chains encompass various components: from sourcing raw materials, through production, storage, distribution, to the delivery of medicines to pharmacies and hospitals. A failure at any stage can have serious consequences for patients.

Discover how blockchain technology can improve supply chains in the pharmaceutical industry.

What are smart contracts and how do they work?

Imagine blockchain as a virtual ledger or accounting book, in which the details of all transactions between entities - such as a company or a customer - are recorded. Importantly, it is impossible to change or delete records in this ledger without the knowledge and consent of both parties. Any change is immediately detected, making the records transparent and indisputable.

This means that there is no possibility to reverse a transaction or change its content or parameters. Once recorded, the information remains unchangeable and accessible to all authorized persons.

Meanwhile, smart contracts are scripts operating on blockchain technology that automatically execute the terms of a contract encoded in them.

Imagine you are the owner of a fruit store and want to add apples to your offer. The customer, on the other hand, wants to be sure that the apples are fresh, organic, and come from natural farms. What would this whole process look like if smart contracts were used?

  1. When the orchardist harvests the apples, information about the date and place of harvest is recorded in the blockchain. This way, you and your customers know where the fruits come from and when they were picked.
  2. The transporter, who takes the apples to the store, scans a code and information about the transport appears in the blockchain. Every stage of the journey is recorded, so you know how long the transport took and what conditions prevailed during it.
  3. When the apples arrive at the store, the seller scans them again, adding information about the receipt of goods to the blockchain. This provides a complete history of the apples - from picking to reaching the store shelf.

Smart contracts automatically execute specified actions when predetermined conditions are met. For example, if apples do not reach the store within a specified time, the blockchain will execute a refund to the store.

Compared to traditional contracts, smart contracts are characterized by:

  • Speed - transactions are executed automatically, without delays associated with the process of accepting terms or human verification of data;
  • Security - thanks to cryptographic confirmation of transactions in the blockchain, third-party interference becomes virtually impossible;
  • Transparency - each party has insight into the contract code and can verify its operation;
  • Lower costs - the transaction does not require any intermediaries, thereby saving on commissions and additional fees.

Smart contracts can have a wide range of applications in the pharmaceutical industry: from orders and logistics to automatic payments upon the fulfilment of contract conditions.

Challenges in pharmaceutical supply chains

Pharmaceutical supply chains are highly complex. Their success is crucial for people's health and lives, hence they must be safe and reliable. However, the sector faces numerous problems.

One of the main threats is the counterfeiting of drugs. According to estimates by the World Health Organization, up to a million people die each year from taking counterfeit drugs. The lack of transparency and the inability to fully verify the origin of medications facilitate this type of criminal activity.

Another issue is quality management and compliance with legal standards. With complicated supply chains involving multiple entities, there is a risk associated with the interruption of continuity in appropriate storage conditions.

Logistical challenges are also significant, such as global shortages of key substances or supply disruptions related to transportation problems.

Cybersecurity is another concern - hacker attacks or breaches of confidentiality can disrupt the operation of IT systems that support the supply chain.

All this demonstrates how complex the pharmaceutical supply chains are and the challenges they face. Modern technologies, such as smart contracts, can help in addressing these challenges.

Application of smart contracts in the pharmaceutical industry

Smart contracts have numerous applications that can bring tangible benefits to pharmaceutical companies.

Firstly, they streamline processes and increase operational efficiency. For example, executing orders for raw materials or packaging through contracts can completely eliminate paperwork. Payments are triggered automatically upon the delivery of goods. The distribution of drugs to wholesalers or pharmacies can also be carried out without involving administrative departments.

Contracts also make it easier to monitor the circulation of products in the supply chain. Data about transport and storage conditions recorded in the blockchain allow for checking the history of each batch of drugs: from the production stage to delivery to the patient. This enables quick responses to any irregularities.

Smart contracts also facilitate compliance with regulations, for example, by automatically blocking the distribution of drug batches that have not passed quality tests. As a result, processes are transparent, making it easier to obtain certification.


Smart contracts in practice - case studies from the pharmaceutical industry
