Good Distribution Practice: Protecting Medicines Across the Supply Chain

The supply chain is where good medicines go bad — a temperature excursion in transit, a weak handover, a partner nobody really qualified. Good Distribution Practice exists to protect products from the moment they leave the manufacturer until they reach the patient. Here is how to protect the distribution chain at every link.

1. Qualified partners

Every supplier, haulier and customer in your chain should be approved and verified. Strong supplier and vendor management is the first line of GDP defence.

2. Temperature control

Cold-chain and ambient products alike need mapped, monitored and alarmed conditions — with the data to prove the temperature held the whole way.

3. Secure transport

Routes, vehicles and handovers should be designed to prevent loss, theft, tampering and mix-ups. Security is a quality control, not only a logistics one.

4. Documentation and traceability

You should be able to trace any unit from dispatch to delivery. Complete, contemporaneous records are what turn a recall from a crisis into a controlled process.

5. Risk management

Map the weak points in your chain and mitigate them deliberately — the longest transit legs, the third-party handovers, the temperature-sensitive lines.

6. Recall readiness

Test that you can act fast and completely. A recall you have rehearsed is one you can execute under pressure.

The Responsible Person's role

Every Wholesale Dealer's Authorisation needs a Responsible Person to own GDP — and many growing distributors use a contract RP to get senior oversight without a full-time hire. See how we have helped others in our case studies, or get in touch.
