Production & Sterilization of Biopharmaceutical Nanoemulsions using Filtration: Microfluidics and Pall Life Sciences Collaborate to Develop a Filtration- based Alternative to Terminal Sterilization for a Squalane Emulsion

Nanoemulsions have many advantages to the pharmaceutical industry as drug delivery systems. These advantages include increased drug loading, enhanced bioavailability, protection from degradation, and controlled drug release. Additionally, the ability of nanoemulsions to enhance immune response makes them useful as vaccine adjuvants.

Large scale production of pharmaceutical nanoemulsions requires precise control of particle size and size distribution since both will determine the stability of the nanoemulsions, and greatly affect terminal sterile filtration. Due to the nature of many of these drug delivery systems (or the drug itself) terminal sterilization with heat is often not an option, and sterile filtration is employed. However, validation of sterile filtration with these solutions can require increasingly robust technical solutions.

This educational webinar will present an example of the process development of a drug delivery nanoemulsion using MicrofluidicsTM innovative high pressure, high shear fluid processing technology in combination with successful sterile filtration utilizing a pre-filtration step (Supor® Grade EKV 0.2 µm rated filter) followed by sterile filtration at three different pressures (15, 30 and 60 psid) with a Fluorodyne® EX Grade EDF filter . The unique capability of a Microfluidizer to produce nanoemulsions with targeted size and size distribution are demonstrated.

Participants will learn:

  • The unique advantages of Microfluidizer® and interaction chamber technology.
  • Process development for producing pharmaceutical nanoemulsions.

Martha Folmsbee, Ph.D.

Principal Scientist
Scientific and Laboratory Services
Pall Life Sciences
(Port Washington, NY, USA)

Martha Folmsbee is a Principal Scientist in the Scientific and Laboratory Services department at Pall Corporation, based in Port Washington, NY. Martha specializes in bacterial and bacteriophage retention testing of sterilizing grade filters. Her work includes a special focus on mycoplasma filtration (mycoplasma clearance) and sterile filtration of low surface tension fluids, particularly in relation to specific customer applications. Martha received a Masters in Environmental Science from the University of Oklahoma in 1997 and later her PhD in Microbiology in 2004. For her PhD dissertation, she studied the physiology and nutritional requirements of anaerobic growth and biosurfactant production of Bacillus mojavensis and several other bacilli. In 2005, she was awarded an ASM/NCID (American Society for Microbiology/National Centers for Infectious Disease) Post Doctoral Fellowship to work at the CDC (Center for Vector Borne Disease) in Fort Collins, CO. There, she studied the physiology and nutritional requirements of Borrelia burgdorferi with a focus toward the development of defined media for the culture of this organism.
