Supplier audits

Compliance with cGMP, GLP or GCP does not depend solely on the company’s own organization; compliance requirements extend to any critical service provider.

The audit of providers of critical materials or services is an essential activity for their qualification which, in turn, is one of the key milestones of the Pharmaceutical Quality System in an environment that, at the operational level, is increasingly fragmented and globalized.

The audit provides an insight into the level of confidence that can be placed on the quality system of our suppliers and in their compliance with associated regulations, so that it can be ensured that the extended operations of drug manufacturing comply with GxP and that the quality of the drug is not adversely affected by supplier operations.

The services that are generally audited are the following:

GMP Services:

  • Contract manufacturing
  • Active substances (API)
  • Excipients
  • Packaging material

GDP Services:

  • Distribution of medicines and starting materials
  • Storage of medicines and starting materials
  • Transport of medicines and starting materials
  • Logistics operators

GCP Services:

  • CRO

General services:

  • Cloud services, IT, software and integrator
  • Pharmacovigilance
  • Cleaning of work clothes
