GDP is for activities relating to the wholesale handling, storage and distribution of pharmaceuticals, traditional medicines, health supplements and cosmetics. The GDP guidelines cover areas such as licensing, organisation and management, personnel, premises and facilities, documentation, operations, complaints and recalls, transportation and distribution records. A GDP system helps to preserve the quality, safety and efficacy of products along the supply chain and ensures medicines are delivered to the correct recipients. It also provides traceability in the event of problems such as a recall.
