Frontida's Center of Excellence, based in AURORA, IL is a best-in-class operation for Fluid Bed Technology and manufacturing. With over 25 years' experience in branded drug R&D and production, as well as contract development and manufacturing, we asked Jim McAndrew to offer some key insights into how Frontida provides expanded capabilities using Wurster coating processes.
Fluid Bed Processors: For Better and 'Wurster'
Jim McAndrew VP of Operations and Process Technologies
Setting The Standard
The fluid bed processors equipped with Wurster coating located at Frontida's Aurora, IL site originated from what once proudly stood as a Fluid Air™ assembly and engineering site and Fluid Air’s PharmPro CMO operation. Following Frontida’s acquisition of this facility near Chicago, the operation retained its original patented equipment and patented processes, along with their industry leading personnel who have spent decades working in the field and optimizing world-class processes for Fluid Air equipment.
What Exactly is Wurster Coating?
Wurster coating fluid beds are completely customizable systems that produce superior applications of high quality, reproducible films onto particulate materials such as powders, beads, mini-tablets, crystals, and granulations. This industry leading equipment ensures precise incremental layering that minimizes the potential risk of agglomeration between particles, and has the ability to tackle complex drug release challenges. Wurster coaters atomize these coating solutions or suspended particle flows and reduce air velocity and distribution. This process allows each individual particle to circulate fully throughout a state-of-the-art coating chamber without the risk of destruction; resulting in superior performance every time.
The control systems installed on Frontida’s Wurster coating fluid beds are flexible in their ability to handle a variety of aqueous and solvent coatings and managing critical process parameters while increasing batch sizes. They also possess data collection capabilities unique to Frontida BioPharm, Inc that allow us to harness the equipment capabilities to their fullest potential. The original inventors of 5 technology patents and processes issued to Fluid Air continue to work for Frontida, resulting in a high level of quality and know-how in Wurster coating and fluid bed manufacturing. This in-house expertise was utilized from the ground up in developing Frontida’s Aurora site for the purpose of adapting many types of process conditions to specific and varied product specifications. Unlike other multipurpose pharmaceutical facilities that install standard fluid beds designed only to fulfill general needs for 2 – 3 products with respect to equipment loading / lift size, air handling conditions, and liquid application, Frontida's equipment was designed with expanded engineering capabilities that can incorporate extreme conditions with precise tolerances.
There are some important examples of the expanded engineering capabilities offered at Frontida. Since our Wurster coater process blower is scaled to nearly 60% larger than any other of its size; our fluid beds have the ability to lift much denser materials than typical, allowing larger batch sizes that result in significant economies of scale. Additionally, Frontida's Wurster equipment can handle significantly higher inlet temperatures, and significantly lower dewpoint temperatures beyond standard designs, providing quality reassurance that even exotic processes can be handled at the site. All of Frontida’s development and commercial equipment is highly automated, and our fluid beds collect 110 different data points every 10 seconds of processing time. This information is then available for both engineering and development teams, providing dynamic insights that optimize the drug development process. These capabilities have provided Frontida the opportunity to be a leader in developing and commercializing extended release mini-tablets, drug-layered beads/resins, and granules, including those with multiple release and API populations. When you work with Frontida, you can trust that this same team of experts is available to work on your product-specific technical challenges, employing the best that our equipment and trained personnel can offer.
