Solutions for Injectables and Parenteral Formulations

Sterility is key for high-risk applications such as injectables, parenteral formulations, ophthalmic and peritoneal dialysis solutions, and many more. The regulatory landscape has been evolving with increased demands from regulatory agencies to improve patient safety.

Mitigating Risk for Injectable and Parenteral Formulations

High-risk products must be sterile and essentially free from endotoxins. A manufacturer cannot rely only on terminal sterilization processes or quality control testing to assure that these requirements are met. Key considerations for high-risk application include:




Autoclave

Selection of Sterility Method

Terminal sterilization is the method of choice as it limits potential errors, is possible to validate and control and, as a result, supports improved patient safety. However, it might not be possible to use in all cases for example due to incompatibility of the selected packaging option or potential degradation products.

Whether terminal sterilization or aseptic processing and sterile filtration is used, minimizing risk throughout the process is critical to yielding a safe product with the environment, personnel, components, equipment, and processes as typical factors to consider. In addition, quality control, risk assessment, and risk management must be in place.

Secure, Consistent, Risk-Mitigated Raw Materials

To mitigate risks, it is best to reduce bioburden quantities throughout the entire process. Microbial contamination presents a risk to the patient and may also induce formulation and API instabilities. By-products caused by microbial contamination are equally critical and may potentially go undetected with established routine tests. This is why it is important that bioburden quantities are controlled in potential sources of contamination.

Minimized bioburden levels through the choice of raw materials and aseptic processing support pre-sterilization microbial loads that are appropriately low for the selected sterility method to ensure the final sterility of the drug product.

The Endotoxin Challenge

It is difficult to remove endotoxins from raw materials, and nearly impossible to remove them from the formulation. Compared to other types of formulations, endotoxins in parenteral formulations pose an added risk to patient safety. Therefore, these have stricter regulatory requirements with respect to endotoxins.

Precautionary measures are therefore critical especially when the materials are from natural sources or are biologically produced, or when non-sterile bulk steps or preservation-free solutions are involved.
