Thank you for subscribing to the latest news from Jenike and Johanson about our pharmaceutical offerings. This newsletter covers including preparing for continuous manufacturing, characterizing powder properties during product development and recent developments in applying blend and content uniformity acceptance criteria.
We can assist you with all stages of your product and process development from initial formulation development to scaling-up for manufacturing. We offer a full suite of services, including flow properties and segregation testing, process assessments, root cause analysis of blending and content uniformity concerns and process and equipment recommendations. We have also assisted clients to implement various programs, including meeting quality-by-design (QBD) and specific FDA requirements, to improve quality and reduced time-to-market.
Please contact us if we can assist you with your powder handling challenges.

We are often asked what key | How do I navigate the evolving blend and content uniformity acceptance criteria? |
 In August 2013, the FDA withdrew the FDA draft Guidance “Powder Blends and Finished Dosage Units – Stratified In-Process Dosage Unit Sampling and Assessment” (Oct. 2003). Since then, it has been challenging to ensure that uniformity sampling plans and acceptance criteria are properly applied. The ISPE’s Blend and Content Uniformity Working Group formed to develop recommendations and acceptance criteria based on the FDA’s concerns. Read More
