Good Distribution Practice, or GDP, is the standard used to cover the movement and transport of materials.  Historically GDP covered the movement of finished product from the pharmaceutical manufacturing site to the wholesalers and retailers and strictly speaking this is still the case.  However with ever more complicated movements of starting materials, intermediate products and finished products then the principles of GDP can apply throughout the whole supply chain – covering the movement of all materials both to and from a pharmaceutical manufacturing site.

The European Union’s GDP guidelines were updated on the 7th March 2013.  Its requirements (Ref: 2013/C 68/01) come into force 6 months after this date and it applies to the movement of finished pharmaceutical products.  You can download a copy here:  GDP New.  Like GMP Good Distribution Practice has a series of Chapters (10 in all) and these can be seen below.  In this post we will highlight the main requirements of the new GDP guidelines, which are much more details than the previous version from 1994 (Ref: 94/C 63/03).  For reference the old version of GDP is here – feel free to quickly look at this: GDP Old

1.            Quality Management

In the chapter on Quality Management there is an increased emphasis on the quality system setting out in detail additional expectations on how the QMS should operate.  This includes the requirements for having systems for Change Control, Corrective Action and Preventive Action, Management Review and Quality Risk Management.

2.            Personnel

In the chapter on personnel there is the need for an adequate number of competent personnel, organisational charts, job descriptions and initial and on-going staff training.   Personnel should also be trained in GDP and hygiene.  The roles and responsibilities of the Responsible Person (RP) are also defined and these are highlighted next.  There is also the requirement that the RP should be continuously contactable.

The duties of the Responsible Person (RP) are also defined in Chapter 2.  These include:

– Implementation and maintenance of the QMS.

– Management of activities and quality of records.

– Initial and continuous training of personnel.

– Coordinating any recall operations.

– Ensuring that customer complaints are dealt with.

– Ensuring that suppliers and customers are approved.  Note that customers also need to be approved!  This is rare for many normal organisations.  Here it means that you only supply medicines to organisations who are authorised to receive them.

– Approving any subcontracted activities.

– Ensuring that self-inspections are performed.

– Keeping appropriate records of any delegated duties.

– Deciding on the final disposition of returned, rejected, recalled or falsified products.

– Approving any returns to saleable stock.

– Ensuring that any additional requirements imposed on certain products by national law are adhered to.

3.            Premises & equipment

There should also be suitable premises and equipment.  This includes clean, orderly, safe and secure storage of materials that will not negatively affect their quality.  There is also the requirement for validation of equipment and computer systems as well as temperature mapping of storage areas and on-going monitoring.  There also need to be adequate records of repair, maintenance and calibration activities for key equipment.

 4.            Documentation

The chapter on documentation has many of the general principles that are also found in GMP.  These include that they should be clear, understandable and free from errors.  Documentation should be approved, signed and dated by appropriately authorised persons.  They should be regularly reviewed and kept-up-to-date.  Records should be completed at the time of action.  Alterations made to entries in records should be signed and dated and the alteration should permit the reading of the original information.  Note that there is no specific requirement that entries to paper-based records be made in ink.  Documents should be retained for at least 5 years.

5.            Operations

The chapter on operations see a detailed expansion of requirements.  These includes the requirements to ensure that all suppliers and customers are legitimate and authorised (bona fide) to handle medicinal products and that appropriate due diligence has taken place.  Storage conditions should be suitable for the items stored.  There should be careful control of picking, supply, export and destruction of unwanted materials.  There is also a new requirement for using stock that is First Expiry First Out (FEFO) rather than First In First Out (FIFO) so older stock is used first.

 6.            Complaints, returns, suspected falsified medicinal products and medicinal product recalls

There are no major changes to the requirements on complaints, returns, suspected falsified medicinal products and medicinal product recalls.  The requirements include that complaints are recorded, a nominated person should deal with complaints and necessary follow-up action should occur.  Returns need to be carefully controlled.  The distributors must immediately inform the competent authority and the marketing authorisation holder of any medicinal products they identify as falsified or suspect to be falsified.  Finally effective recall mechanisms need to be in–place.

7.            Outsourced activities

With any outsourced activities a written contract between the contract giver and the contract acceptor should exist.  This should establish and define the duties of each party.

8.            Self Inspection

There is also a more detailed requirement for self-inspection within the new guide to GDP, and this follows the similar principles of self-inspection in GMP.  In essence self-inspections should be conducted according to a programme, performed by independent personnel, be recorded, the results made available to management and followed by appropriate actions to deal with any issues seen.

9.            Transportation

There are many new additional requirements of the new guide to GDP when it comes to transportation.  This follows lots of problems and concerns in this area. The requirements include that products should be shipped according to the labelled conditions and that excursions are reported.  There are detailed requirements for shipping temperature sensitive items.  Contracted transporters should be informed of storage conditions.  Note that there is no mention of “ambient” or recording temperature during “ambient” transportation however there is a need for a documented risk assessment of delivery routes to identify when temperature control is needed.  In all cases suitable and secure storage conditions are required.  Finally there is the requirement to use dedicated vehicles where possible.

10.          Specific provisions for brokers

The final chapter of GDP covers specific provisions for brokers.  This is a totally new addition to GDP and requires that suitable systems are in place for individuals or organisations involved in the sale or purchase of medicinal products.

This is a simplified overview of the new GDP guide.  It has many more detailed requirements than its predecessor.  You should read the full document however to gain your own understanding.  I hope that this post is useful.  If you need any help with any GMP / GDP or Quality related training and consultancy – please get in touch at  [email protected] or visit our website.
