EP6.0 5.1.1. METHODS OF PREPARATION

OF STERILE PRODUCTS)

Dry heat sterilisation. For this method of terminal sterilisation the reference conditions

are a minimum

of 160 °C for at least 2 h. Other combinations of time

and temperature may be ud provided that it has been

satisfactorily demonstrated that the process chon delivers

an adequate and reproducible level of lethality when

弓箭手英文operated routinely within the established tolerances. The

procedures and precautions employed are such as to give an

SAL of 10− 6 or better.

Dry heat sterilisation is carried out in an oven equipped with

forced air circulation or other equipment specially designed

for the purpo. The sterilir is loaded in such a way that

a uniform temperature is achieved throughout the load.

Knowledge of the temperature within the sterilir during

the sterilisation procedure is usually obtained by means of

temperature-nsing elements inrted into reprentative

containers together with additional elements at the

previously established coolest part of the loaded sterilir.

The temperature throughout each cycle is suitably recorded.

Where a biological asssment is carried out, this is obtained

using a suitable biological indicator (5.1.2).

Dry heat at temperatures greater than 220 °C is frequently

ud for sterilisation and depyrogenation of glassware. In

this ca demonstration of a 3-log reduction in heat resistant

附件1-2 2.6.14. BACTERIAL ENDOTOXINS

The test for bacterial endotoxins is ud to detect or

quantify endotoxins of gram-negative bacterial origin

using amoebocyte lysate from horshoe crab (Limulus

polyphemus or Tachypleus tridentatus). There are

3 techniques for this test : the gel-clot technique, which

is bad on gel formation ; the turbidimetric technique,

bad on the development of turbidity after cleavage of an

endogenous substrate ; and the chromogenic technique,

bad on the development of colour after cleavage of a

synthetic peptide-chromogen complex.

The following 6 methods are described in the prent

chapter :

Method A. Gel-clot method: limit test

江西省高考分数线Method B. Gel-clot method: mi-quantitative test

Method C. Turbidimetric kinetic method

182 See the information ction on general monographs (cover pages)

EUROPEAN PHARMACOPOEIA 6.0 2.6.14. Bacterial endotoxins

Method D. Chromogenic kinetic method

Method E. Chromogenic end-point method

Method F. Turbidimetric end-point method

Proceed by any of the 6 methods for the test. In the event

of doubt or dispute, the final decision is made bad upon

method A unless otherwi indicated in the monograph.

The test is carried out in a manner that avoids endotoxin

contamination.

1211 STERILIZATION AND STERILITY ASSURANCE OF COMPENDIAL ARTICLES

This informational chapter provides a general description of the concepts and principles involved in the quality control of articles that must be sterile. Any modifications of or variations in sterility test procedures from tho described under Sterility Tests 71 should be validated in the context of the entire sterility assurance program and are not intended to be methods alternative to tho described in that chapter.

Within the strictest definition of sterility, a specimen would be deemed sterile only when there is complete abnce of viable microorganisms from it. However, this absolute definition cannot currently be applied to an entire lot of finished compendial articles becau of limitations in testing. Absolute sterility cannot be practically demonstrated without complete destruction of every finished article. The sterility of a lot purported to be

sterile is therefore defined in probabilistic terms, where the likelihood of a contaminated unit or article is acceptably remote. Such a state of sterility assurance can be established only through the u of adequate sterilization cycles and subquent aptic processing, if any, under appropriate current good manufacturing practice, and not by reliance solely on sterility testing. The basic principles for validation and certification of a sterilizing process are enumerated as follows:
