Potent-compound awareness training for operators is important to understand why the containment and controls are in place.

Washington, DC (Aug. 14)?A new report issued by the Pharmaceutical Research and Manufacturers of America identifies 418 drugs and vaccines developed through biotechnology. All of the biotechnology medicines and vaccines are now in clinical trials or awaiting approval by the US Food and Drug Administration (Rockville, MD).

Novozymes (Bagsvaerd, Denmark) made an offer to acquire the the biotechnology company GropPep Ltd (Adelaide, Australia) for DKK 375 million ($65 million) to build its position in supplying ingredients to the biopharmaceutical industry. Novozymes is a major producer of enzymes, including biocatalysts used in pharmaceutical synthesis.

Combinatorial catalysis in asymmetric synthesis and asymmetric biaryl Suzuki coupling highlight recent advances in chiral chemistry. Plus the marriage of green and chiral chemistry.

Examples of genuine strategic partnership agreements between end users and vendors are relatively rare in custom synthesis.

Select large custom manufacturers expand capacity, private equity firms buy companies in transition, and players from India and China build their positions.

China is on the rise as a center for pharmaceutical R&D, but companies are still getting their footing for operating in China and the services industry has some maturing to do.

The hydrophilic matrix system continues to be the most popular and widely used strategy to achieve extended drug release. Hypromellose (hydroxypropylmethylcellulose [HPMC]) is typically the polymer of choice for the rate-controlling carrier in these systems.

Degussa AG (D?sseldorf, Germany) and Lynchem Co., Ltd. (Dalian, Liaoning Province, China) signed a contract to establish a custom manufacturing joint venture.

Gilead Sciences, Inc. (Foster City, CA) signed a definitive agreement to acquire the Canadian subsidiary Raylo Chemicals and most of its assets from Degussa AG (D?sseldorf, Germany) for 115.2 million euros ($147 million).

CMOs account for 20–30% of biopharm production. Big Pharma also is filling the biologics supply chain.

Bioequivalence with the reference product is the only reliable measure of demonstrating the therapeutic equivalence of a generic product to the innovator product. Systematic and comprehensive innovator product characterization can be used to make generic product development easier. This involves characterization of API and quantification of the critical excipients. The latter contributes towards performance of the final dosage form. This article describes the capsule formulation of a poorly water-soluble drug, celecoxib, which contains sodium lauryl sulphate as a critical excipient. The importance of a decoding process aimed at developing a generic product that matches the innovator formulation in a discriminating dissolution method is demonstrated.

AstraZeneca PLC (London, England) has agreed to acquire the biopharmaceutical company Cambridge Antibody Technology Group PLC (CAT, Cambridge, England).

Indian suppliers of active pharmaceutical ingredients and dosage formulations expand in India, the United States, and Europe.

New biocatalytic and chemocatalytic routes to chiral intermediates and developments in simulated-moving-bed and supercritical-fluid chromatography for resolving racemic mixtures.

Pellets are a multiparticle, solid form of medication. The individual pellets are almost spherical with diameters usually between 100 and 2000 ?m.

Facing still-sluggish market conditions and a changing world order in fine chemicals, the large Western custom manufacturers are responding by building their toolboxes in specialized technologies in chiral chemistry, catalysis, and biosciences and by adjusting their manufacturing networks via streamlining or investment in Asia.

Human plasma provides a rich source of therapeutic medicines, including gamma globulins, coagulation factors, albumin, alpha anti-trypsin and others. In 2001, sales of immuno gamma-globulin (IgG) were estimated at $2 billion with a production rate of 50 metric tons for the year.1 A number of therapeutic products have been introduced including Gammimune from Bayer, RhoPhylac from ZLB Behring and Octagam from Octapharma.

The manufacturing process used for an API’s production is a crucial factor determining its quality.

This is a year of change for the Synthetic Organic Chemical Manufacturers Association (SOCMA), the Washington, DC-based trade association representing chemical batch and custom manufacturers. Following the sale of Informex, its flagship trade show, last fall, the association is advancing key programs, most notably its new ChemStewards program, an environmental, health, safety, and security initiative (EHS&S) that its members began implementing last month.

Although physicochemical preformulation screening is practised universally within the pharmaceutical industry, physicomechanical screening is applied to a lesser extent and often only where a problem exists.

Applications of adsorption of small drug particles at the surface of large excipients were introduced, and different factors affecting adsorption process were discussed and summarized. Several examples of adsorbing drugs to excipients to increase dissolution rate were exhibited in this article.

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.

The survival of Bacillus subtilis spores in dicalcium phosphate, lactose, and corn starch and in their binary mixtures depends on the compressional properties of these materials and on parameters involved during the tableting process, including compression speed.

The previous studies on the incorporation of glyceryl monostearate into pellets by extrusion/spheronization has been extended to include a range of grades of this material plus a mixed medium chain partial glyceride and two glycerol esters of hydrogenated natural glycerides as described in this article.

Palatinit's "galenIQ" is line of multifunctional excipients that offer the combined advantages of other bulk excipients.

Making active pharmaceutical ingredients (APIs) requires long chains of chemical reactions and large quantities of solvents. Ask API manufacturers how they'd like to improve this process, and the responses are likely to be "make the reactions faster," "make the reactions cheaper," or "make the reactions more efficient." Then after all these economically driven answers, you might here, "make the reactions more environmentally friendly."

Chemical purity is the most important quality characteristic of a pharmaceutical substance. This article describes the latest scientific and technological advances to meet recent pharmacopoeial and regulatory requirements regarding the control of organic impurities in synthetically produced active substances. Future developments and suggestions for those working in quality control and raw material selection are discussed.

A polymer excipient that reportedly reduces spray time has received its first registration in a finished drug product.

Poly(ethylene oxide) is gaining the attention of research and development organizations and its application is extending into a wide range of drug delivery systems.
