Formulation and Drug Delivery

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.

Big Pharma is ramping up capital spending in parenteral manufacturing at the same time that contract manufacturers are completing their own major investment programs.

Transdermal drug technology specialists are meeting demands for methods that can painlessly deliver larger molecules in therapeutic quantities.

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.

Single-use products enhance sterile filtration by making it easier to maintain sterility and reduce cross-contamination risks.

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 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.

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.
