A new Raman spectroscopic method to detect magnesium stearate in powder blends and tablets is described. High-volume pharmaceutical manufacturing requires the use of lubricants to facilitate tablet ejection from compressing machines. However, lubricants may also bring a number of undesired problems that have been widely documented in pharmaceutical scientific literature. New analytical methods are needed to understand lubrication and provide process knowledge in support of FDA's process analytical technology initiative. The detection of magnesium stearate in lactose, mannitol, corn starch and other commercially important excipients is reported. The Raman spectroscopic method has a detection limit of about 0.1% (w/w) based on the 2848 cm-1 band that corresponds to the symmetric stretch of the methylene group in magnesium stearate.

Predicting the flow characteristics of powders during manufacture is especially important for the pharmaceutical engineer. Getting the powder flow wrong can be highly disruptive to plant performance and productivity, particularly where equipment has to be taken off-line and stripped down for cleaning out blockages. The flow behaviour of the individual ingredients may be well known, but as these are blended and reacted their flow properties can change.

One of the major concerns with introducing PAT, however, is that the bias towards process engineering may not ultimately lead to complete control of product quality.

There is a tremendous need to enhance delivery of potential therapeutics to the brain for treatment of central nervous system (CNS) disorders. The blood brain barrier (BBB) restricts and controls the exchange of compounds between the CNS and the blood, which requires discovery of new modalities allowing for effective drug delivery to the CNS. Polymer nanotechnology has now become one of the most attractive areas of pharmaceutical research. This review focuses on the current progress in polymeric nanoparticles, where the specific arrangement of the polymeric matter at the nanoscale is utilized to design drug delivery systems that provide safe and efficient transport of CNS drugs across the BBB.
