Compounding Pharmacy

Charles River offers FDA-licensed products and cGMP-compliant services to maintain control and consistency in your compounding processes, from in-process testing to batch release.

Pharmacies that prepare individualized dosages of sterile drugs for patients must meet stringent requirements and standards to assure patient safety. Our FDA-licensed products and cGMP-compliant services for compounding pharmacists help maintain control, consistency and reduce risks associated with manufacturing in an aseptic environment.

Sterility Testing

Sterility testing is designed to demonstrate the presence or absence of extraneous viable contaminating microorganisms in biological parenterals designed for human use.

The sterility test is applied to substances, preparations or articles, which, according to the United States Pharmacopeia (USP) and European Pharmacopoeia (EP), are required to be sterile. Sterility testing is used for bulk and final drug products, cell banks and raw materials.


Bacterial Endotoxins Testing

The Bacterial Endotoxins Test (BET) detects unsafe levels of microbial cell wall debris, from live or dead Gram-negative bacteria, that cause fever or septic shock.

Traditional methods of the BET require skilled analysts and manipulation of cumbersome reagents. Our endotoxin testing systems provide faster results for improved process efficiency and ease-of-use over traditional methods while offering additional benefits of portability, improved accuracy, and reproducibility. The Endosafe®  nexgen-PTS™ yields quantitative endotoxin results in approximately 15 minutes, which translates into fewer bottlenecks and faster production, improved sample management, and the assurance that your products are free of endotoxin (pyrogen) within limits set by the United States Pharmacopeia (USP).
