RT Journal Article T1 Endotoxins from a Pharmacopoeial Point of View A1 Franco Gil, María Elvira A1 García Recio, Veronica A1 Jiménez López, Pilar A1 Garrosa, Manuel A1 Girbés Juan, Tomás A1 Córdoba Díaz, Manuel A1 Córdoba Díaz, Damián AB A pyrogen is a substance that causes fever after intravenous administration or inhalation. Gram negative endotoxins are the most important pyrogens to pharmaceutical laboratories. In the International, United States, Japanese and European Pharmacopoeias, there are two official methods to evaluate pyrogenicity—that is, the bacterial endotoxin test, and the pyrogen test. The main objective of this review is to compare the monographs of each test among the different Pharmacopeias, to detect similarities and differences. The former can be considered fully harmonized, and only non significant differences were detected. The latter, which is the only available assay for some products and formulations to demonstrate apyrogenicity, shows large differences, which should be considered.
