title: Establishment of a replacement batch for heparin sodium biological reference preparation.
abstract: An international collaborative study was organised to replace the current European Pharmacopoeia biological reference preparation for heparin sodium. The project was organised by the European Directorate for the Quality of Medicines & HealthCare in the frame of its Biological Standardisation Programme. A suitable candidate batch representative of the quality of heparin products currently marketed in Europe was donated to the EDQM and included in a collaborative study involving 19 laboratories from 10 European countries, the Americas, Australia and the Council of Europe. Laboratories were requested to perform their routine assays following the prescriptions of the Ph. Eur. for the assay and the identification of unfractionated heparin and for the assay of protamine. The results made it possible to demonstrate that the candidate batch was suitable for its intended use and it was therefore established by the European Pharmacopoeia Commission as the Ph. Eur. heparin sodium BRP batch 3 in June 2007.
