Particle Contamination Challenges – USP 788 : Are you ready for the chapter becoming official on August 1, 2026 ?

📃 The USP <788> chapter “Particulate Matter in Injections” is evolving and will become officially applicable on August 1, 2026.

Following updates published in July 2025, this chapter introduces important clarifications and progressive changes (USP-PF).

🎯 A key challenge : adapting analytical methods to complex matrices

One of the main challenges of this regulatory evolution is improving the management of particle analysis, particularly in complex matrices.

🔍 Focus on oily suspensions

These types of matrices may create significant analytical constraints, including :

• Turbidity
• Viscosity
• Interferences

These parameters can make Method 1 (Light Obscuration) unsuitable. In such situations, Method 2 (Microscopy) may become necessary, provided its use is supported by a robust and well-documented scientific rationale.

⚙️ Anticipating USP <788> requirements : a structured approach

To effectively address these new expectations, it is essential to :

• Assess method applicability
• Review critical analytical parameters
• Conduct feasibility studies recommended to secure method selection and analytical strategy

This approach helps anticipate regulatory constraints while ensuring reliable results.

🤝 At CEBIPHAR, we provide :

• Both methods available on the same site
• A fast and reliable assessment of product behavior and foreign particulate nature
• Business continuity ensured for Method 1 thanks to dedicated backup equipment

Anticipating these expectations is now essential to secure your development and control strategies.
