The PANDRH Technical Working Groups system was switched in 2015 to a project based approach in prioritized areas-the following is historical information...

PANDRH Working Groups consist of groups of experts in areas that have been identified as priorities for drug regulatory harmonization. Members are selected by the steering committee and confirmed by the regulatory authorities of the respective countries. Whenever possible, working groups have at least one representative from each of the five sub-regional blocs of the Americas.

Academics and other experts can be members of the working groups. Each group's main objectives include the implementation of diagnostic studies in order to identify the differences among the countries regarding the implementation of international standards and to define the necessary strategies for technical cooperation, analyze international guidelines, and prepare harmonized proposals in their areas to be considered during the conference for implementation in the region. PANDRH rules and regulations (available only in Spanish) have a specific chapter on Working Groups operation; also available: the member list of the technical working groups (2010).

La misión del grupo de trabajo de vacunas es la de promover la armonización de la reglamentación farmacéutica para las vacunas con vista a garantizar su calidad, seguridad y eficacia, generando mecanismos mas eficientes que contribuyan a su disponibilidad para los países de las Américas.

Biotechnological products are medicines produced from animal cell substrates and microbial cultures. Constitutes proteins obtained by the recombinant DNA technique expressed in animal tissues or in microbial life forms, including products obtained through the monoclonal antibody technique 1. The World Health Organization also uses biotherapeutic products name to refer to biotechnological products.

Mission, purpose and documents.

Mission: Develop and strengthen Pharmacovigilance through regulatory harmonization activities and proposals that promote the safety and rational use of drugs as a necessary component of public health policies in the Americas.

Mission: To promote and harmonize criteria for medicines promotion as a contribution to the rational use, within the scope of health policies in the Americas.

Working Group on Good Clinical Practices documents, Mission and Objectives.

It presents the mission, objectives and documents.

Since its creation in 1999, the GT / CFM has focused on the formulation of proposals for the development of policies and strategies for implementation by countries, development and promotion of training programs for process optimization of inspection and capacity building/ investigation; and promoting the exchange of information.


This Working Group on Good Laboratory Practice (WG/GLP) was created in June 2005 by recommendation of the Fourth Pan American Conference for Drug Regulatory Harmonization (PARF Network) of PAHO. The formation of this group was based on the excellent work and results obtained up until that time by the external quality control program (PCEC).

The PCEC measures the performance of the official laboratories for control of medicines in the region and sends them blind samples for analysis. The results are evaluated by the United States Pharmacopeia (USP). The medicines controlled to date have been in the PAHO programs on antimalarial drugs, anti-tuberculosis drugs, and HIV/AIDS drugs. The PCEC works under the direction of PAHO/WHO. It has technical assistance and financial support from the USP.

The working group held its first meeting in the city of Panama (1-3 June 2005). At this time, the group was established and defined its mission, objectives, and a 2-year work plan.


Strengthen the performance of the official laboratories for control of medicines (LOCM) in the countries of the Region of the Americas through implementation of Good Laboratory Practice, in order to guarantee the quality of the laboratory test results and facilitate mutual recognition of the results.

A. Documents prepared 

B. Course on Good laboratory practices(GLP) for the Official Laboratories for Control of Medicines (LOCM)

Background: The Pan American Network for Pharmaceutical Harmonization (PANDRH Network), through the Technical Working Group on GLP (WG/GLP), developed a proposal for a course on good practices for national pharmaceutical control laboratories. This course has been implemented in several countries of the Region. It will be presented at the Fifth Pan American Conference on Drug Regulatory Harmonization to be held in 2008.


  • Promote use of the WHO recommendations for GLP: Report 36, Annex 3 (Technical Report Series 902, 2002).
  • Improve the performance of the quality control laboratories.
  • Circulate and promote use and correct implementation of the Self-Evaluation Guide on GLP of the PANDRH Network.
  • Increase the communication and exchange of information between the official quality control laboratory, local manufacturers of medicines, and the academic sector.
  • Update the knowledge of the staff members of the Ministries of Public Health and the academic sector with regard to the latest WHO recommendations on GLP.

Educational Materials

4. Courses given

The team of instructors for each course consists of three professionals, a combination of university professors and professionals from pharmaceutical quality control laboratories. There are two basic criteria that should be met in all cases. All of the courses should have at least one facilitator from the university (teaching experience) and a facilitator from an official laboratory (practical experience). It is recommended that the facilitators should be from different countries, since this enriches the discussion of the subjects. They are usually from three different countries. In all cases, it is stressed that they should be from at least TWO different countries. A professional from the United States Pharmacopeia (USP) is also available to explain the proper use of the USP-NF and present a DVD on a commonly used technique (e.g., TLC, HPLC). The group of facilitators includes: Ruben Szyszkowsky (Universidad de Buenos Aires, Argentina); Catalina Massa (Universidad de Córdoba, Argentina); Rosalba Alzate (Universidad de Antioquia, Medellín, Colombia); Carlos Saldarriaga Alzate (Universidad de Antioquia, Medellín, Colombia); Milagros Real Pérez (National Center for Quality Control, INS, Peru); Fredy Rafael Mostacero Rodríguez (National Center for Quality Control, INS, Peru); Antonio Hernández Cardoso (United States Pharmacopeia); José M. Parisi (PAHO/WHO)
