Good Distribution Practice Explained: A Guide for Pharmacy and Clinic Buyers

Good Distribution Practice (GDP) is the quality standard that governs how medicines are stored, handled and moved between manufacturer and patient. If you buy medicines for a pharmacy or clinic, GDP is what protects the product between the factory gate and your premises.

The core principles

GDP is built on a simple idea: the quality of a medicine should be exactly the same when it arrives as when it left the manufacturer. To achieve that, a GDP-compliant distributor must control:

• Storage conditions, including temperature monitoring and mapping of warehouses and vehicles.

• Traceability, so every batch can be followed forward to customers and back to its source.

• Supplier and customer qualification, so stock only moves between authorised parties.

• Returns, recalls and complaints, with clear written procedures.

• Training, so every person handling stock understands their role.

What GDP means for you as a buyer

You are part of the chain too. Pharmacies and clinics should store stock correctly on arrival, check deliveries against invoices, and report damaged or suspicious products quickly. A good wholesaler will make this easy by supplying clear paperwork and responding fast when something goes wrong.

Questions to ask your supplier

• How are temperature-sensitive products packed and monitored in transit?

• What happens if a delivery arrives outside its temperature range?

• How quickly will I be told about a recall affecting stock I hold?

GDP is not just a regulatory box. It is the reason you can trust what is in the box. At Acorn Pharmaceuticals, GDP sits at the centre of how we source, store and deliver for our customers.
