Manufacturing

The big question for pharmaceutical services providers coming into 2006 is: will the good times continue to roll?

Manufacturers, FDA, and research organizations are collaborating on efforts to spur innovation and streamline drug production.

Hot melt extrusion (HME) formulation development depends heavily on choosing the appropriate polymers. This article reviews HME process parameters and highlights three polymers in HME: polyethylene oxide, ethylcellulose, and hypromellose.

Contract manufactures are faced with multiple challenges when determining whether to implement process analytical technology into their clients' or their own infrastructure.

Almost all pharmaceutical manufacturing processes require handling and processing cohesive powders. The application of sufficient shear (i.e., the total deformation that the bulk of granular material undergoes under applied shear stress) is an essential factor in such processes. Sufficient shear is required to mill and de-lump materials, achieve sufficient flow, and homogenize cohesive ingredients. Shear mixing plays a critical role in the blending of dry powders, particularly for those that contain a minor cohesive component such as a solid lubricant or a drug. This mechanism is necessary to achieve a satisfactory homogeneity and disintegrate possible agglomerates. Excessive shear can be disadvantageous, however, and can lead to electrostatic buildup, attrition, and overlubrication.

Solid oral drug products are one of the oldest of all manufactured dosage forms (1). Today, the development of an appropriate formulation of drug and excipients and of an effective manufacturing process to create a tablet or capsule is slowly transforming from a practice of applied art to one of applied science. The US Food and Drug Administration supports this change by expecting sponsors of new drug applications to understand, describe, and control materials and processes as well as the risks associated with drug product manufacturing (2). These steps will ensure the consistent production of products that meet their specifications and remain safe and effective during their shelf life.

Continuous manufacturing processes?little used in the pharmaceutical industry but the norm in oil, food, chemical, and polymer manufacturing?go hand-in-hand with the current emphasis on quality-by-design and automated process monitoring and control (aka, process analytical technology, PAT).

The process analytical technology (PAT) initiative has been percolating at the US Food and Drug Administration for a long time, explained FDA's John E. Simmons at the AAPS Annual Meeting and Exposition on Wednesday. "If you think of PAT as an isolated set of applications, I think you are missing the point," Simmons said. "The FDA would like PAT to become commonplace?not to be an initiative, but common practice."

This week, the US Food and Drug Administration posted an Oct. 20 Warning Letter (http://www.fda.gov/foi/warning_letters/g5567d.htm) sent by its Minneapolis, MN district office to Diversified Manufacturing Corporation (Newport, MN).
