Pyrogen test is performed to examine the existence or absence of pyrogens in all aqueous parenterals. Rabbits are utilized to conduct the test simply because their physique temperature raises when pyrogen is introduced with the parenteral route.
one. How can I create a sampling program for in-method testing and completed item release?
The pyrogenic principles of micro organism Specifically Gram unfavorable micro organism are frequently attributable to some warmth-stable substances secreted by these organisms; and which if located in parenteral medications could induce fever (an increase in the body temperature with the host using the medication). This phenomenon necessitates the necessity to constantly test and detect the presence of pyrogens in intravenous medications and various parenterals so the batch of the merchandise containing fever-inducing agents may very well be stopped from achieving the general public.
For human and animal medication, some USP monographs even now require a rabbit pyrogen test. Despite these types of monographs, a company may perhaps substitute an endotoxins read more test or substitute mobile-based test In the event the business can show equivalent pyrogen detection.
one. Direct inoculating the test sample on an acceptable tradition medium at the best possible ailments for bacterial development
The reaction of each and every rabbit is detected by the real difference of initial temperature and the very best temperature recorded. The response of all a few rabbits gives the sum of responses and may be concluded as:
