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.

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.

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 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.
