Pharmaceutical Science & Technology Innovations

New technologies, along with changes in FDA oversight, may provide a critical path to make more new drugs available more quickly to patients.

Drug makers and their suppliers will need good planning and organization to meet the new bar coding requirements for drug products used in hospitals.

From data acquisition to enterprise resource planning, software systems operating at all levels of pharmaceutical manufacturing prepare for the seemingly inevitable implementation of process anlytical technology.

Total organic carbon (TOC) analysis is a fast and effective analytical technique for cleaning validation. Understanding the various types of TOC technologies is essential for choosing the best solution.

This article describes the formulation of a tablet for a specific purpose, primarily using fractional or full factorial designs. The formulation work generated a matrix that was processed by two software packages based on neural networks. When the dataset was divided into smaller subsets, the agreement between the predicted and observed tablet properties of the optimized formulations was reasonable.

FDA's draft guidance on aseptic processing contains some inherent difficulties, including unrealistic expectations of sterility and microbial quantification, an absence of harmonization with international rules, and failure to support new technologies or a risk-based approach. The authors propose a science-based alternative.

In this article, the authors describe a study into the factorial effect of selected process parameters on the pharmaceutical characteristics of poly(DL-lactide-co-glycolide) microspheres containing methotrexate. A study of the microspheres' stability at refrigerated temperatures is also examined.

In spite of regulatory uncertainties, the industry continues to develop improved aseptic processing technologies.

Current microbiological methods cannot measure microbial contamination at the levels that engineers and regulators seek to establish for aseptic processing cleanrooms. New approaches for assessing data and establishing alert and action levels are advocated, and an example of one analytical tool is considered.

A new active dry powder inhaler has been developed using vibration frequencies to aerosolize powders.

FDA relies on e-chips to thwart bogus products, and drops paper pedigrees and unit-of-use packaging.

Protecting a product from temperature abuse is gaining importance as regulators seek proof of product stability throughout the distribution process.

The author covers the fundamentals of lyophilization and provides case studies about the development of lyophilized biopharmaceutical products and the importance of biophysical characterization in formulaiton and the lyophilization process.

Electrical resistance, low temperature scanning calorimetry, and freeze-drying microscopy are three analytical methods that can be used to determine the thermal characterization of a product during processing for intended development of a lyophilization cycle.

Hydrogen peroxide has become the compound of choice for gaseous biodecontamination in the pharmaceutical industry. As some processes operate at vapour concentrations below the dew point, to avoid condensation, and others actually form dew, it is important to understand the relationship between the vapours and to have a method of establishing the dew point.

Though recognized by the public since freeze-dried coffee hit the market 30 years ago, lyophilization remains far from mature and deserves more research.

The authors establish a quantitative framework for understanding the correlation between the segregation of pharmaceutical powders and various physical and process parameters.

This article describes the use of a one-pot processor for the cleaning and cleaning validation of two drug compounds - water-soluble theophylline and water-insoluble mebendazole. Both substances were produced using wet granulation and microwave drying, after which the processor was cleaned using its clean-in-place (CIP) system. Swab samples were taken from areas considered critical during processing and analysed for remains of active ingredient. It was concluded from the results that the processor's CIP system is capable of removing both moieties to a level well within accepted regulations.

With new features such as servo-controlled operations and modularity, today's packaging machines offer enhanced flexibility, increased uptime, and reduced product waste.

Based on a German initiative, an international standard on quality management systems for the primary packaging materials of medicinal products is discussed in this article. This new directive will help to standardize the production of primary packaging materials by defining global requirements.
