- USP - Microbial Enumeration Test
The presence of microorganisms in sterile drug products is of paramount concern to patient safety. However, it may be less obvious why concern for the presence of microorganisms in non-sterile drug products NSDPs exists.
Growth promotion testing of culture media appears to be a trivial test, but this perception is deceiving. Almost everyone can agree that with the criticality of microbiological tests, it is extremely important that culture media performs properly. Culture media is used in most assays in a microbiology laboratory, and if the media does not properly support growth, false negative results may be obtained. Likewise, contaminated media may yield false positive results.

Clients must now specify which microorganisms are required to be absent. This requirement is based on the unique characteristics of the product based on formulation process, raw materials, etc. The Suitability of the Test Method demonstrates that the test specimen to which the testing is applied does not, of itself, inhibit the recovery of the microorganisms that may be present. The performance of the Suitability Test ensures that any antimicrobial activity inherent in the sample to be tested does not adversely affect the reliability of the test and that the test procedure to be routinely utilized is otherwise suitable for use with the sample. The new USP methods are now more inclusive for more organisms.
P harmaceutical products are classified into two groups according to the microbiological point of view: 1 sterile products and 2 non-sterile products. The sterilized term refers to the products that are free of any microorganisms, their production were done under aseptic conditions, but the production of non-sterile products were not under aseptic conditions 1 ; they are not free from microorganisms; for this type of products legal authorities defined microbial limit ranges. The requirements for non-sterile products acceptance depending on the legal authorities of different countries or even different pharmaceutical companies may vary slightly. These microorganisms can grow under certain temperature and nutritional conditions and could affect the quality and safety of the product. Contamination at any stage of the process can represent a serious risk to the final product and must be controlled so to maintain the quality and safety of the product 3. Very few products, such as syrup and elixir, have a preservative nature.
This chapter provides tests for the estimation of the number of viable aerobic microorganisms present and for freedom from designated microbial species in pharmaceutical articles of all kinds, from raw materials to the finished forms. An automated method may be substituted for the tests presented here, provided it has been properly validated as giving equivalent or better results. In preparing for and in applying the tests, observe aseptic precautions in handling the specimens. Preparatory Testing. The validity of the results of the tests set forth in this chapter rests largely upon the adequacy of a demonstration that the test specimens to which they are applied do not, of themselves, inhibit the multiplication, under the test conditions, of microorganisms that may be present. Therefore, preparatory to conducting the tests on a regular basis and as circumstances require subsequently, inoculate diluted specimens of the material to be tested with separate viable cultures of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Salmonella.
USP Updates and for Microbial Testing of Non-Steriles
Friedman Ph. These Chapters present information that relate to both non-sterile and aseptic processing. Several of these chapters have been recently updated and all have been updated since Each of these Chapters has relevance to each other and provides a significant knowledge base of microbiological requirements. Several of these have also been harmonized and permit one to not only follow the USP, but simultaneously meet the requirements of both the European and Japanese Pharmacopeia. Friedman, ensuring that trainees will be provided with the most up to date and practical information on the topic. This multi-part live training program is instructed by Dr.
USP - Microbial Enumeration Test
Scott Sutton, Ph. It appears here with permission. However, the signed-off versions have yet to be published. This makes the description of the test a bit difficult, as the current tests will be disappearing, and the final, harmonized test is not yet public knowledge. However, we do know that the harmonized tests do not differ greatly from the drafts published in USP a, USP b, USP c , and so we will use those drafts as the description of the finalized test.
