Pharmaceutical logistics compliance: distribution practice from dock to dispatch

Authorisation, and the person who can stop a release

Wholesale distribution of medicinal products in the European Union requires an authorisation, and the guidelines on good distribution practice set out how the holder must operate. Central to the system is a designated responsible person with defined duties and the authority to act on them, including refusing to release stock. That authority has to be real: a quality role that can be overruled by operations is a finding waiting to happen. A logistics provider working for an authorisation holder rather than holding its own operates under a written contract that allocates responsibilities precisely, with the client retaining accountability and auditing the provider. The contract, the quality agreement and the audit programme are the mechanism by which the regulated party discharges its duty over an activity it has outsourced.

Qualified counterparties on both sides

Distribution practice restricts who may be bought from and sold to. A distributor must verify that its suppliers are entitled to supply and that its customers are entitled to receive, which in practice means holding and periodically refreshing evidence of the relevant authorisations, checking that ordering entities match the qualified record, and applying heightened scrutiny to unfamiliar counterparties and unusual order patterns. Those checks are also the principal defence against falsified medicines entering the legitimate chain, alongside the safety features and verification arrangements introduced for prescription packs. Anything bought outside the qualified route, however attractive the price, is the classic entry point for falsified stock.

Premises, storage conditions and mapping

Storage areas must maintain the conditions the product requires, with temperature mapping performed under representative load conditions to identify hot and cold spots, monitoring devices placed accordingly, and alarms that reach someone able to respond. Segregation is required for rejected, recalled, returned and expired stock, and for products subject to additional control such as narcotics. Equipment qualification and calibration records, cleaning, pest control and access control all form part of the same picture. So does a documented plan for power failure and equipment breakdown, since the regulator's interest is less in whether an incident occurs than in whether the response was defined in advance and executed.

Transport, returns and destruction

Products must be transported so that their conditions are maintained, with the route and packaging chosen deliberately and the conditions capable of being demonstrated after the fact. Vehicles and equipment are qualified where required, and the distributor stays responsible for the product even where transport is subcontracted. Returns are where inexperienced operators create real losses. Stock returned from a customer may generally be placed back into saleable inventory only where defined conditions are met, including evidence that the required storage conditions were maintained throughout the time it was out of the distributor's control. Where that cannot be shown, the product is quarantined and destroyed under a controlled, documented process. Recalls run on a similar footing, with the ability to reach every recipient of a batch quickly being the capability that matters.

Documentation as the compliance product

In this sector the record is the deliverable. Procedures, training records, deviation and corrective action files, self-inspection reports, temperature data, batch traceability and change control together constitute the evidence that the system works, and an activity performed correctly but not documented is treated as not having been done. Exactly which requirements bind a given operation depends on the jurisdiction, the authorisations held and the contract with the authorisation holder. Providers should work from the current guidelines applicable to their territory and take specialist advice rather than relying on general descriptions such as this one.

Frequently asked questions

Can returned medicines go back into saleable stock?

Only where the defined conditions are satisfied, including demonstrable evidence that required storage conditions were maintained while the product was outside the distributor's control. Without that evidence the stock is quarantined and destroyed under a documented process.

Does outsourcing distribution transfer the regulatory responsibility?

No. The authorisation holder remains accountable and discharges its duty through a written contract, a quality agreement and an audit programme covering the provider. The provider carries contractual obligations and, where it holds its own authorisation, direct ones as well.

Why is temperature mapping done under load?

Because an empty room behaves differently from a full one: racking, pallet mass, door openings and airflow all shift where the extremes sit. Mapping under representative conditions is what makes the placement of monitoring devices meaningful.
