Pharmaceutical Newsletter – Aug 2015


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.

Are You Ready for Continuous Manufacturing?


Although continuous manufacturing has been used in other industries for centuries to produce products ranging from glass bottles to breakfast cereals, it is still in its infancy in the pharmaceutical industry.  This situation has often prompted the question among pharmaceutical companies, vendors and regulatory agencies: “If continuous manufacturing is routine for other consumer products, why can’t we do it too?” Read More

What key powder properties should be measured during development?

Fluidization-segregation-tester-material-sparingWe are often asked what key powder properties should be measured at different stages of product development, particularly during formulation development vs. validation and commercial production.  Learn about the benefits, requirements, and applications of material testing during development and production. Read More

How do I navigate the evolving blend and content uniformity acceptance criteria?
Navigation1In August 2013, the FDA withdrew the FDA draft Guidance “Powder Blends and Finished Dosage Units – Stratified In-Process Dosage Unit Sampling and Assessment” (Oct. 2003).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

What are the best practices for measuring flow properties in a shear cell?

PastedGraphic-1Although the value of shear tests is well established, there is often a lack of basic guidance for the characterization of common attributes.  Jenike & Johanson’s James Prescott and Andrès Orlando have joined industry and academic scientists in detailing best practices for the characterization of the flow performance, as presented in a new Pharmacopeial Forum chapters (USP General Chapter <1063>). Read More
