Development Begins on Mutated H5N1 Virus Vaccine

Novavax, Bharat Biotech Team for Pandemic Influenza Vaccine Development

Quantitative data from the literature show strong relationships among average particle size, powder densification, tensile strength, and hardness.

Transdermal 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.

BMS Receives FDA Approval for Transdermal Antidepressant

Because of the growing popularity of single-use materials, the identification, characterization, and qualification of new materials used for disposable processes have become increasingly important for both regulatory and production purposes. This article describes one approach to identifying and validating the materials used in a disposable filling process.

GSK Gains Approval for Rotavirus Vaccine in Infants; FDA Review Extended for Merck’s Shingles Vaccine

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.

FDA Recommends Changes for 2006-2007 Flu Vaccine

Baxter Wins Contract to Develop Cell-Based H5N1 Vaccine

Cambrex (East Rutherford, NJ) to produce Geron (Menlo Park, CA) telomerase anti-cancer vaccine. Generex (Toronto, ON.) files IND for synthetic vaccine to stimulate cell-mediated immunity to avian influenza. Dow Agrosciences (Indianapolis, IN) wins USDA approval for veterinary vaccine, the first manufactured via plant cell culture. G-8 nations pledge billons for vaccine production.

Merck wins approval for rotavirus vaccine as Sanofi ships investigational H5N1 vaccine to NIH and CDC explores new flue diagnostics and novel vaccine-production technology.

Dow AgroSciences Receives Regulatory Approval for Plant-Made Vaccine

The pharmaceutical industry's focus on process understanding, monitoring, and control is driving manufacturers to take greater steps toward identifying possible manufacturing bottlenecks earlier in the development process. For tablet, capsule, and excipient producers, such efforts include taking a closer look at the flow-ability of their powders.

Cell-Grown Vaccine Protects Against Avian Flu Virus

Using a novel automated microfilling system, the authors demonstrate that roller compaction followed by milling is a viable preprocessing technique for high-dose chemical-in-capsule dosage forms. The process results in higher bulk and tapped densities for drug substances compared with milling alone.

Though dissolution testing has been under scrutiny, it is still a powerful test method.

This article discusses the advantages and disadvantages of using solid-state NMR spectroscopy for the analysis of pharmaceutical solids.

Sanofi Pasteur and BD Team Up to Produce Microneedle Vaccines

Using the Bergum Method and the MS Excel software program, the author determines the probability of passing the USP dissolution test.

SEC Loosens Revenue-Recognition Rules for Vaccine Stockpile Participants

NIAID Boosts Vaccine Innovation but Draws Controversy

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.

Almost all pharmaceutical manufacturing processes require handling and processing cohesive powders. The application of sufficient shear (i.e., the total deformation that the bulk of granular material undergoes under applied shear stress) is an essential factor in such processes. Sufficient shear is required to mill and de-lump materials, achieve sufficient flow, and homogenize cohesive ingredients. Shear mixing plays a critical role in the blending of dry powders, particularly for those that contain a minor cohesive component such as a solid lubricant or a drug. This mechanism is necessary to achieve a satisfactory homogeneity and disintegrate possible agglomerates. Excessive shear can be disadvantageous, however, and can lead to electrostatic buildup, attrition, and overlubrication.

Solid oral drug products are one of the oldest of all manufactured dosage forms (1). Today, the development of an appropriate formulation of drug and excipients and of an effective manufacturing process to create a tablet or capsule is slowly transforming from a practice of applied art to one of applied science. The US Food and Drug Administration supports this change by expecting sponsors of new drug applications to understand, describe, and control materials and processes as well as the risks associated with drug product manufacturing (2). These steps will ensure the consistent production of products that meet their specifications and remain safe and effective during their shelf life.

Chiron Looks to Flu Vaccine Cell Culture; FDA Gears Up

Control Development's (South Bend, IN, www.controldevelopment.com) blend uniformity and dryer monitor consists of a NIR spectrometer, a sampling head, computer, and software.

Generally, tablet and capsule film coatings are applied as aqueous or organic-based polymer solutions or dispersions, graduate student Sagarika Bose (University of Connecticut) explained during her Tuesday AAPS Graduate Student Symposium presentation, "Development and Evaluation of Solventless Photocurable Pharmaceutical Film Coating." However, organic film coatings can be flammable, toxic, and must comply with strict environmental regulations. Aqueous film coating can lead to the degradation of certain drugs by heat and water.
