Performance Survey and Comparison Between Rapid Sterility Testing Method and Pharmacopoeia Sterility Test

The sterility test described in pharmacopoeial compendia requires a 14-day incubation period to obtain a valid analytical result. Therefore, the use of alternative methods to evaluate the sterility of pharmaceuticals, such as the BacT/Alert® 3D system, is particularly interesting, because it allows a reduced incubation period and lower associated costs. Considering that the BacT/Alert® 3D system offers several culture media formulations developed for this microbial detection system, the present study was aimed to evaluate and compare the performance of BacT/Alert® 3D with the pharmacopoeial sterility test. There was no significant difference between the ability of the culture media to allow detection of microbial contamination. However, the rapid sterility testing method allowed a more rapid detection of the challenge microorganisms, which indicates that the system is a viable alternative for assessing the sterility of injectable products.
