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.

This article describes the quality of highly purified water and its applications, addressing why ultrafiltration (UF) is being used as a downstream purification process. It aims to show that UV is a real alternative for producing pyrogen-free water. This method allows essential cost savings compared with distillation and guarantees a higher safety than other membrane methods such as reverse osmosis.

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.
