The USP pyrogen test has further limitations Apart from endotoxin tolerance and small reactivity to legionnaires' endotoxin. Amongst they're its variability in test final results when compared to the identical preparing of standardized endotoxin. This affliction is influenced get more info by seasonal variation, interlaboratory elements, rabbit species to species attributes, along with other biological influences.
As with parenteral drug products, sterile units have from time to time been proven being contaminated with endotoxins. Sources have been water which someway entered into your production process.
The effects of endotoxin are linked to the level of endotoxin inside the item dose administered to a affected person. Since the dose varies from products to products, the endotoxin Restrict is expressed as K/M. K is 5.0 EU/kilogram (kg.), which represents the approximate threshold pyrogen dose for human beings and rabbits. That's the level at which an item is adjudged pyrogenic or non-pyrogenic.
