The function of the Responsible Person (RP) in the context of pharmaceutical wholesale distribution, as outlined by Good Distribution Practice (GDP) plays a crucial role in preventing falsified medicines from entering the legitimate pharmaceutical supply chain. Falsified medicines are counterfeit or substandard drugs that can pose serious risks to patient health. Here’s how GDP contributes to preventing the distribution of falsified medicines:

  1. Traceability and Documentation: GDP emphasises the importance of accurate record-keeping and documentation throughout the pharmaceutical supply chain. This includes maintaining detailed records of product movements, transactions, and storage conditions. This traceability ensures that the provenance of medicines can be established, making it easier to identify and isolate any falsified products.
  2. Supplier Qualification: GDP requires pharmaceutical wholesalers and distributors to thoroughly vet and qualify their suppliers. This includes conducting supplier audits and assessments to ensure that suppliers meet quality and authenticity standards. Falsified medicines often enter the supply chain through unscrupulous or unreliable suppliers, so supplier qualification is a critical preventive measure.
  3. Storage and Handling Standards: Proper storage and handling of pharmaceutical products are fundamental aspects of GDP. Medicines must be stored under appropriate conditions to maintain their integrity and efficacy. Compliance with GDP guidelines reduces the risk of counterfeit or substandard medicines entering the supply chain due to improper storage.
  4. Temperature Control: Some falsified medicines involve products that have been exposed to inappropriate temperatures, which can lead to product degradation. GDP mandates proper temperature control measures, including temperature monitoring and validation of temperature-controlled storage facilities and transportation. This helps prevent the distribution of substandard or altered products.
  5. Security Measures: GDP requires the implementation of security measures to protect pharmaceutical products from theft, diversion, and tampering. These measures include security systems, access controls, and monitoring of storage facilities. By enhancing security, GDP reduces the opportunity for counterfeit medicines to enter the supply chain.
  6. Regular Audits and Inspections: GDP mandates regular self-inspections and audits of distribution facilities. These audits help identify any deviations from standard operating procedures and can uncover unauthorized or suspicious activities that may be associated with the distribution of falsified medicines.
  7. Product Verification: GDP requires thorough checks of product authenticity upon receipt and before distribution. This involves verifying the identity, condition, and labeling of pharmaceutical products. Suspicious or unverified products can be isolated and investigated to prevent their distribution.
  8. Change Control: Any changes in the distribution process, suppliers, or storage conditions must be carefully evaluated and controlled under GDP. This ensures that any alterations to the supply chain are well-documented and do not inadvertently introduce falsified medicines.
  9. Communication and Reporting: GDP promotes open and transparent communication with regulatory authorities. If any suspicious or counterfeit medicines are identified, regulatory agencies can be alerted promptly. Timely reporting enables swift action to remove falsified products from the supply chain.


In summary, GDP establishes a robust framework for the proper distribution of pharmaceutical products, emphasising traceability, quality, security, and compliance with regulatory standards. By adhering to GDP guidelines, pharmaceutical distributors can reduce the risk of falsified medicines infiltrating the legitimate supply chain, ultimately protecting patient safety and public health.
