What is difference between content uniformity and blend uniformity? The main difference between content uniformity and assay is that content uniformity is a test in which evaluation units are done individually whereas assay is a test in which multiple units are done simultaneously. Furthermore, the evaluation procedure of content uniformity tests is the same for all units.
02-10-2015· Blend Uniformity- Content Uniformity USP <905> does not use a statistical sampling plan, therefore the results provide limited statistical assurance that future samples from the batch would meet acceptance criteria. FDA no longer supports the approach stated in the withdrawn guidance document nor the use of USP <905> for batch release

03-01-2012· Jan 03, 2012. Blending, one of the most basic of pharmaceutical unit operations, can also be one of the most challenging to control. Solid formulations contain multiple ingredients beyond the active pharmaceutical ingredients: fillers, tabletting agents, disintegrants, and absorption enhancers or agents that slow down and control absorption.

Conduct a suitable blend uniformity evaluation whenever the uniformity of the content at the Formed Dosage Unit stage is outside of its established expectations. Conclusion Testing final blend uniformity as a suitable in-process control may well evaluate and highlight the incoming ingredient batch-to-batch differences as well as the physical variations in different lots of active materials.
