From data to knowledge: the challenge in bioprocess development
September 1st 2007In biomanufacturing, multiple sensors provide a wealth of data that could be used to enhance process understanding and assist in performance improvement. This article looks at how to move from a data-rich environment to one where the data are translated to useful information that leads to knowledge and, ultimately, process improvements.
Preparing rapid disintegrating tablets containing taste-masking microgranules
September 1st 2007This 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 Raman spectroscopic method to monitor magnesium stearate in blends and tablets
September 1st 2007A 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.
Scale-up trials of foam-granulation technology — high shear
September 1st 2007The 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.
New FDA Guidance on Polymorphic Compounds in Generic Drugs
July 12th 2007A new guidance issued by the US Food and Drug Administration earlier this month advises companies on how to treat polymorphic drug compounds?those that exhibit multiple structural forms?in filing abbreviated new drug applications.
Injectable Administration Systems
July 2nd 2007During the past 30 years, manufacturers developed sophisticated packaging and delivery systems to support the requirements of traditional and complex biologics, including quality and cleanliness. This article discusses the evolution of packaging and delivery systems for injectable administration systems as the pharmaceutical and biotechnology industry evolved during the past 30 years. It also explores the future of packaging and delivery systems as technology and drug development advance.
Changes in Pharmaceutical Formulations and Drug Delivery Systems
July 2nd 2007The author reviews advancements in formulation that Pharmaceutical Technology has chronicled during the past 30 years. During this time, many novel solutions were investigated and finally became common and accepted techniques. The author also looks ahead to future developments in formulation and drug delivery methods.
FDA Issues Draft Guidances for Online Access of Bioequivalence Studies for Generic Drugs
June 7th 2007Rockville, MD (May 31)-The US Food and Drug Administration issued a draft guidance on how to design bioequivalence (BE) studies for specific drug products to support abbreviated new drug applications (ANDAs).
