Recent regulatory initiatives have emphasized the need to improve pharmaceutical manufacturing. PAT marked the beginning of a number of regulatory efforts to encourage innovation and a transition towards science-based manufacturing. This article reviews the progress of the regulatory initiatives and describes two significant research initiatives to develop a future pharmaceutical manufacturing environment based on scientific understanding of pharmaceutical materials and processes.

This article presents collaborative positions among excipient manufacturers, drug product manufacturers, and members of the US Pharmacopeia on key issues pertaining to the control of pharmaceutical excipients stemming from a recent Pharmaceutical Quality Research Institute workshop.

Larger and strategic sampling and testing plans can improve process understanding and characterization.

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

In 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.

This article investigates how the industry can test inhalers in a way that is most representative of typical use.

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 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.

Identifying polymorphs is a crucial part of the drug-development process as researchers forward select methods to improve detection.

The authors examine advances in the design and the application of biological indicator evaluator resistometer vessels used to measure the resistance of bacterial spores in monitoring sterilization processes.

Double-digit growth is projected for the US generic drug market, and the industry positions for opportunities in biosimilars.

The racemic compound (R, S)-(±)-ibuprofen is a popular and well understood active pharmaceutical ingredient, but it has several disadvantageous formulation properties such as poor solubility, low melting point, and potential esterification with excipients containing an hydroxyl group. The authors investigate the use of an (R, S)-(±)-ibuprofen salt to evaluate these problems using various analytical methods to determine the polymorphism, crystallinity, and drying scheme.

Fluidized hot melt granulation (FHMG) is an emerging technique combining the advantages of both dry and wet granulation methods, and represents an innovative continuous granulation process capable of mixing and agglomerating excipients and active pharmaceutical ingredients (APIs) to produce uniform blends of particles suitable for use in the manufacture of pharmaceutically elegant solid dosage forms.

Sterile liquids are frequently transferred during the processing of sterile liquid drugs such as injectables or ophthalmic drops. Several types of transfer can be performed, each requiring a validated method to ensure the desired sterility-assurance levels are achieved.

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.

Rockville, MD (May 1)-The US Food and Drug Administration issued a guidance to alert pharmaceutical manufacturers, pharmacy compounders, repackers, and suppliers to the potential public health hazard of glycerin contaminated with diethylene glycol (DEG), a poison.

Mixed-mode chromatography sorbents and custom ligands aim to optimize protein purification.

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.

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.

Green chemistry involves redesigning processes so that more of the raw material ends up in the product, rather than as waste...

Interphex2007, New York, NY (Apr. 26)-Robustness studies for analytical methods are critical in being able to provide the assurance to the quality of an analytical method, a topic addressed in a conference session, "Performing Analytical Method Validation Robustness for Regulatory Compliance," at Interphex on Thursday.

Interphex2007, New York, NY (Apr. 25)-One of the challenges facing pharmaceutical manufacturers is how to implement process analytical technology (PAT) into their commercial manufacturing processes. Michael Abad, engineering section manager, Abbott Laboratories shared insight from a project within Abbott in his presentation "Engineering for PAT" at Interphex today.
