The US Food and Drug Administration advised patients, caregivers, and healthcare professionals to switch to hydrofluoroalkane-propelled albuterol inhalers now because chlorofluorocarbon-propelled inhalers will not be available in the US after Dec. 31, 2008.

Creating a kinder, gentler manufacturing process that doesn't kill the product is the goal of process developers doing large-scale cell culture for cell therapy.

The authors demonstrate that anecdotal reports of prednisone tablet variability are inaccurate.

When drugs are encapsulated, electrification (the electrostatic charge of the capsule) may sometimes cause problems, such as capsule adhesion during transportation or dispersion of the capsule content in the filling process.

There are two ways in which 'difficult' samples are usually categorized: either by the problems posed by the physical nature of the post-vivo sample matrix containing the chemical entity to be analysed, or...

Once famous for coal and steel, Wales now aims to make its mark in the life sciences sector. The recent BioWales 2008 (UK) conference demonstrated how much the region has progressed, thanks to the support of the Welsh Assembly government, the EU and the enthusiasm of the Welsh biotech community. The country's bioscience sector, which comprises approximately 200 companies, grew by 18% last year and is now worth £1.3 billion (€1.6 billion) in annual turnover, employing 15–20000 people.

Scientists are giving up on a preventive vaccine for AIDS, but there are lessons to be learned.

Recent advances in SEM, particularly the incorporation of automation and software, have made simpler, lower-end SEM instruments easy to operate and have improved the capabilities of larger, sophisticated instruments.

Traditional tablet presses do not measure tablets' tensile strength, yet this characteristic strongly influences tablet quality. The author describes a compression technique that accounts for tensile strength and produces tablets with consistent weight and disintegration time.

What makes a drug ripe for respiratory delivery?

Monoclonal antibodies and recombinant proteins have increased their importance and gained success as therapeutic agents in the treatment of various diseases.

As the US biopharmaceutical industry and regulators debate new requirements for biosimilars, industry leaders are turning to analytical science to define intellectual property and business development strategies. Emerging techniques are providing previously unseen protein characterization details, giving both innovator and generics companies new weapons in the battle for future market share.

Biopharmaceuticals are the most rapidly growing segment of the pharmaceuticals market. Developing and marketing biopharmaceuticals are huge roles in almost every major pharmaceutical company's strategy. However, they are extremely complex molecules and are highly sensitive to the manufacturing processes used to produce them. These processes require exquisite control of living production systems, making, without a doubt, biopharmaceuticals one of the most challenging products of any type to manufacture.

As a skipping stone creates ripples in a lake, SOA can help create benefits that quickly ripple through many other areas of the organization and partners.

Spraying techniques can be used to produce powder form formulations. The concept works by the adsorption/absorption of a liquid SELF onto a neutral carrier…

A microelectronic system based on radio-frequency (RF) cell ablation addresses limitations of other transdermal drug-delivery methods. This system expands the transdermal spectrum to include the delivery of water-soluble molecules, peptides, proteins, and other macromolecules.

For pediatric and geriatric patients, fast-dissolving drug-delivery systems provide an easier way to take medications and vitamins. Oral thin films have evolved to provide systemic delivery of active pharmaceutical ingredients for over-the-counter and soon, prescription drugs. The authors review the practical benefits of dissolvable films, their manufacture, and their market potential.

Liquid and semisolid encapsulation using two-piece hard capsules is an ideal drug delivery approach for highly potent compounds and poorly water-soluble drugs. The authors detail the factors to reduce risk when designing and operating a facility for secondary manufacturing of highly potent drugs.

Scientists at the University of North Carolina at Chapel Hill have successfully tested a new inhaled tuberculosis (TB) vaccine.

The 59th Pittsburgh Conference gathered more than 1000 exhibitors on its showroom floor this week.

Chemical imaging of solid dosage forms has become a powerful analytical tool for the development of solid dosage forms.

The pharmaceutical industry has experienced a number of difficulties during recent years. Greater competition from generics (more than 60% of prescription drugs are supplied from the generic market) and increased gaps in the drug pipeline that result in acquisitions or strategic alliances has led to a feeling of uncertainty in the bio/pharma marketplace. There have also been changes in the marketplace with a shift from primary care to specialty drugs, the introduction of personalized medicine driving the need for biomarker/diagnostic technology and the introduction of biopharmaceuticals.

To ensure an effective treatment, a patient often must take equal doses of an active pharmaceutical ingredient (API) at regular intervals.

As part of a major project to design and build a new bulk vaccine antigen plant, the authors were asked to investigate and implement a suitable fumigation system for clean room decontamination. The facility was designed to handle and contain live influenza virus, and has clean room suites designed to containment levels CL2 and CL3 according to the Approved Code Of Practice and Guidance (ACOP, Control of Substances Hazardous to Health 4th Edition). From the outset, specific areas within the facility were identified as requiring fumigation and this formed part of the initial design brief.

We are currently experiencing a problem with one of our tablet lines. While the tablets appear white immediately after manufacture, after a time many of the tablets begin to take on a yellowish appearance. Could this be an issue that surface analysis could help resolve?

The authors propose extending initial solvent screening for a single-solvent system to the cocktail solvent screening of binary and ternary solvent mixtures.
