Improving the Physical and Chemical Properties of Ibuprofen
April 20th 2006The common crystal form of ibuprofen was changed to optimize processing and manufacturing properties. Six modified crystal forms were prepared and assessed for dissolution, morphology, particle size, density, thermal characteristics, powder x-ray diffractometry, flow properties, and tabletability.
Sandoz Wins EU Approval, US Progress for Biogeneric Product
April 20th 2006Sandoz (Holzkirchen, Germany), the generics division of Novartis (Basel, Switzerland) received European marketing authorization for its recombinant human growth hormone, ?Omnitrope? (somatropin), making it the first biogeneric product approved under the biosimilar pathway of the European Commission.
The Role of Reverse Engineering in the Development of Generic Formulations
April 20th 2006Being the first to gain the most is a fundamental principle in the generics business because several companies compete to create generics of successful products going off patent. For a generics company to maintain revenue growth in a market in which product prices continue to fall, it must secure a continuous flow of new products, with quality and speed to market being key drivers. Thus, generics companies must be highly skilled in product and process development (1), the generics business, and achieving bioequivalence-the most critical development area.
Virtual screening using chemical feature-based pharmacophores and virtual molecule libraries
April 1st 2006The discovery of suitable lead structures for new drugs from an inexhaustibly large reservoir of theoretically possible compounds is one of the biggest challenges for the pharmaceutical industry. In the last few years, combinatorial chemistry methods have been developed to synthesize a huge amount of diverse new chemical entities (NCEs), which may subsequently be tested for biological activity in vitro.
Scaling down biopharmaceutical operations Part 1: Fermentation
April 1st 2006Creation and qualification of scale-down models are essential for performing several critical activities that support process validation and commercial manufacturing. As shown in Figure 1, these activities include process characterization and production support studies that are performed to evaluate column and membrane lifetimes, demonstrate clearance of host-cell impurities and viruses and troubleshoot manufacturing issues. While the underlying fundamentals are relatively the same as those when scaling up, some unique considerations should be taken when scaling unit operations down.4
Nefopam Containing Transdermal-Matrix Patches Based on Pressure-Sensitive Adhesive Polymers
March 2nd 2006Transdermal matrix-type patches of Nefopam hydrochloride with a combination of pressure-sensitive adhesives were developed. The polymeric composition provided a controlled and sustained release of the drug from the patches and demonstrated favorable physicochemical characteristics.
Viral filtration of plasma-derived human IgG
March 1st 2006Human 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.
