Spraying techniques can be used to produce powder form formulations. The concept works by the adsorption/absorption of a liquid SELF onto a neutral carrier…

Our company is involved in developing and manufacturing APIs that can be utilized with drug-eluting stents (DES). Despite ensuring constancy in pharmaceutical composition, we are experiencing issues with variations in drug release during in vitro studies. We are working closely with a stent manufacturer to develop the system, but could surface analysis techniques investigate the problem further?

We are currently experiencing a problem with one of our tablet lines. While the tablets appear white immediately after manufacture, after a time many of the tablets begin to take on a yellowish appearance. Could this be an issue that surface analysis could help resolve?

The authors consider the advantages of using rapidly dissolving films to accurately and effectively deliver pharmaceutical ingredients, with an emphasis on the importance of controlling moisture content and drug loading during formulation development.

This article describes how rapidly disintegrating tablets containing a large quantity of an intensely bitter drug were successfully developed with a suitable level of masking, tablet hardness, disintegration property, dissolution profile and mouth feel.

A new economical method for producing fast-melting lamina-like dosage forms.

The authors evaluate the scalability of foam-granulation technology using continuous foam addition in high-shear granulation equipment at the laboratory, pilot and manufacturing scales. Immediate- and controlled-release model formulations were used. Continuous and batch addition of foam were compared for the controlled-release model formulation at the manufacturing scale, and physical testing was performed on the granules and finished tablets.

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.
