A comparative study of three air samplers used for bioaerosol collection was performed to evaluate the average recovery of colony-forming units and to assess the precision of each device.

Nanostructured lipid carriers are a new type of delivery system offering improved performance in terms of drug loading and long-term stability with the ability to form highly concentrated dispersions...

X-ray microtomography has great potential for improving the understanding of the structural features of solid dosage forms and the changes in those features during manufacturing, handling, and storage. This article describes the basic principles of the technique and provides examples of its potential applications.

The validation of alternative microbiological testing is an opportunity for a manufacturer to decrease the amount of time required for laboratory results. To properly validate these alternatives, a practitioner must first identify what is being studied. The regulatory effect on established product and process specifications and levels must be completely evaluated, as changing the method of analysis may well change the apparent number in the sample.

In this article, the author explains some of the technology behind using ion-exchange resins for drug delivery...

As newer and more elaborate hardware and software systems are installed in automated manufacturing environments, companies are further incorporating good practices into their validation process.

The author describes strategies for analytical method development that are helpful in achieving quality by design and efficiency.

The Impurity Profiling Group reviews stress testing according to regulatory guidance documents. The authors emphasize what should be considered for late clinical phases and for registration application dossiers.

Analytical instrument suppliers are developing manufacturing-tailored tools that are small, precise, and easy to use.

The United States Pharmacopeia should not change its philosophical position on singlet testing.

A swab-sampling method was developed for cleaning validation of a residual active pharmaceutical ingredient in samples collected after cleaning the sampling suite. A summary of the strategies and results of the method development is presented.

Comparative studies of the US Pharmacopeia (645) "Conductivity" and the European Pharmacopeia "Heavy Metals" tests were conducted to demonstrate that the USP method can determine the presence or absence of heavy metals in process water samples.

By enhancing stability and in vitro drug-release characteristics, limonene enantiomers are a natural-source alternative for developing and characterizing self-nanoemulsified drug delivery systems.

Evaluations have shown, in most cases, visual observations are sensitive enough to verify equipment cleanliness. An experiment was conducted to explore the possibility of using a visible-residue limit as an acceptable cleaning limit in a pharmaceutical research facility, including an evaluation of the limits and subjectivity of ?visually clean? equipment.

Steaming-in-place (SIP) is a widely adopted method for the in-line sterilization of processing equipment. The main advantage of SIP relies on manipulation reduction and aseptic connections that might compromise the integrity of the downstream equipment.
