FDA's recently released initiative has made process analytical technology (PAT) a hot topic in the life science industry. PAT describes the application of process analytical chemistry tools, feedback process control, information management tools, and product and process optimization strategies for the development and manufacture of pharmaceuticals. In this article, the author explores the impact PAT will have on the pharmaceutical industry.
Accurately targeted immunotherapies through reliable neoantigen recognition enable personalized medicine development.
Activation and expansion are essential for success in both autologous and allogeneic therapies.
Continuous manufacturing and a quality-by-design development approach are a natural fit.
The authors suggest a design strategy for an aseptic process simulation that focuses on the basic repeating unit of the process, establishing alert and action criteria for the unit itself, and using worst-case simulations to establish routine operational parameters for the manufacturing process.
A straightforward approach reveals how the probability of passing the USP content uniformity test can be calculated for tablets and capsules.
In this final part of a series of three articles, the results from experiments involving cohesive materials are discussed in terms of mixing performance, agglomerate comminution, and lubrication of powder mixtures.
Customers are placing high demands on pharmaceutical manufacturers to produce sensitive, cost-effective and regulatory compliant inspection technology. This article examines how metal detection equipment suppliers can combine forces with manufacturers to provide state-of-the-art inspection systems, giving particular consideration to cleaning processes and regulatory issues.
The author describes the efforts of the standards committees to establish guidelines for PAT implementation and the impact of the guidelines on the industry.
This article reviews various physicochemical approaches that may be employed to enhance absorption following oral administration of solid dosage forms in humans. This article also examines strategies based on capitalizing or neutralizing physiological processes.
A novel probe design can reduce the powder-sample density variance such that moisture and solvent levels can be accurately modeled and predicted in process.
A new generation of drug delivery devices is being developed. Smart skin patches, it is claimed, will provider a safer and more user-friendly method of taking medication. This article highlights some recent developments in the field and analyses some of the many benefits the patches will provide to patients.
FDA recently approved the first PAT applications for the introduction of rapid microbial testing of drug products and pharmaceutical-grade waters. Officials from FDA and GlaxoSmithKline worked together to ensure the appropriate scientific evaluation of the methods. Team members report on the successful validation approach and identify technical issues to be considered for the future.
The use of stable isotopic analyses to characterize drug products before they leave the manufacturer is explored as a means to identify counterfeit products.
The results of forced degradation studies indicate the need for alternatives to valerophenone as an internal standard calibration for quantifying ibuprofen in bulk drug and tablet assay samples.
The authors examine the VHP resistance of microbial isolates recovered from controlled environments and compared them with commercially available biological indicators under various test conditions.
Most, if not all, pharmaceutical companies today are moving towards a paperless reporting structure. This article examines FDA's 21 CFR Part 11 regulations, which relate to technical and procedural compliance for electronic records and signatures.
If an inspection reveals any shortcomings ... a manufacturer may be warned, fined, or its facility closed down until full control can be demonstrated to the satisfaction of the authorities ....
Automated actuation of nasal sprays removes operator bias during measurement of particle size, spray-plume geometry, and delivered dose.
The electronic tongue technology provides a technically suitable and cost-effective method for screening and directing taste formulation, while eliminating both safety concerns and subjective bias.
