There is a great need for sensitive, precise, and easily accessible analytical detection techniques for protein sequencing.
Carriers for DPIs: formulation and regulatory challenges
October 1st 2006The presence of very low levels of residues (including solvents) in excipients is becoming an important issue for users, and the presence of very low levels of ?non-lactose? species in DPI lactose may pose challenges to suppliers and users.
Mathematical Modeling Speeds Process Scale-Up and Transfer at P&G
September 12th 2006Arlington, VA (Sept. 12)-At the American Association of Pharmaceutical Scientists meeting here, "e;Real World Applications of PAT and QbD in Drug Process Development and Approval" (Sept. 11-12), chemical engineer and process modeler Michael L. Thompson, PhD, described how Procter & Gamble (West Chester, OH, www.pg.com) applies these mathematical tools to increase product quality and reduce development and trouble-shooting time for consumer and pharmaceutical products.
FDA's CMC Pilot Program Moves Forward
September 12th 2006Washington, DC (Sept. 12)-The Office of New Drug Quality Assessment (ONDQA) in the Center for Drug Evaluation and Research (CDER) has approved one new drug application (NDA) under its CMC Pilot Program and has two more applications are under review. The pilot was established last year to provide an opportunity for FDA and industry to explore strategies for including Quality by Design (QbD) principles and process analytical technology approaches in regulatory submissions, explained ONDQA deputy director Chi-wan Chen at the PDA-FDA Joint Regulatory Conference here
The Simplified Akers–Agalloco Method for Aseptic Processing Risk Analysis
July 2nd 2006This article summarizes changes to the Akers–Agalloco aseptic processing risk analysis model (first presented in Pharmaceutical Technology's November 2005 issue) as well as some of the underlying thinking behind the revision. The simplified model makes the method easier to use because of its greater flexibility of environmental control practice. It maintains the emphasis on human activity as the primary consideration in risk management for aseptic processing.
Industry Examines Approaches for Characterizing APIs
June 16th 2006Accurate characterization of active pharmaceutical ingredients (APIs) is a critical part of the drug development process. The approaches used to characterize APIs with respect to structure, identification of impurities, and the solid-state were discussed by Andrew C. Kolbert, manager, molecular structure and spectroscopy, Cardinal Health (Dublin, OH).
Thermal Effusivity and Power Consumption as PAT Tools for Monitoring Granulation End Point
June 2nd 2006Thermal effusivity and power consumption may help predict granulation end point in high-shear granulators. In this study, power consumption was monitored and compared with percent relative standard deviation (RSD) on thermal effusivity measured at-line. Lactose monohydrate, microcrystalline cellulose, and magnesium oxide were granulated, and the effect of load size on granule growth in a fixed-volume granulator was evaluated using three load levels. Load size, liquid addition rate, and impeller speed were measured, and the correlation among RSD on effusivity, power consumption, mean granule specific surface area, and granule compressibility index were determined.
An Approach Using Bezier Curves to Control pH and Decrease Enzyme Inactivity
May 2nd 2006Using Bezier curves, an experimental process controller has been developed for biosynthesis applications in which the inactivity of a pH-sensitive enzyme must be decreased. By taking into account various control scenarios of pH and growth rate, as well as the physical and chemical characteristics of the environment, a suitable human-machine interface can be developed.
Creating a compelling business case for your LIMS implementation
May 1st 2006This article examines the development of a business case to secure coveted funding for a LIMS implementation. Information on hard cost savings and soft benefits of implementing a LIMS system, and managing the compilation of the cost justification are covered.
Using remote monitoring to boost performance
May 1st 2006The evolution of sophisticated monitoring systems has been accelerated because of stringent EU legislation surrounding the pharmaceutical industry and the escalating demand for preventative maintenance techniques. This article gives an overview of the benefits of implementing these systems in pharmaceutical manufacturing.
Survival of B. subtilis spores in Dicalcium Phosphate, Lactose, and Corn Starch
April 20th 2006The 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.
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
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.
