This article provides guidance for developing dissolution testing for poorly soluble compounds. It is the second of a series of articles based on material from a 2003 PhRMA workshop about acceptable analytical practices.

Microspheres of Eudragit RL were developed for colonic delivery of albendazole. The effects of polymer concentration, stirring rate, and concentration of emulsifier on particle size and drug loading were studied. A comparative in vitro drug release study of the optimized formulation was carried out.

With creative engineering and sophisticated chemistry, industry scientists offer big solutions for attaining small particle sizes and narrow distributions.

Granulation is one of the most important unit operations in the production of pharmaceutical oral dosage forms. However, there are many different technologies each having different strengths and weaknesses. Most companies choose which one to use simply based on their own experience. This article introduces different processes, compares them objectively and offers unbiased advice on the merits of each system. It then looks at the implications of selection on two different applications.

Packaging machines for new or existing lines are easier to operate and change over than they ever were before. Today's packaging machines also accommodate a greater variety of heights, diameters, finishes, or dosage regimen counts.

This article describes a novel approach to a scale-up management system, based on a holistic view of the scale-up lifecycle and an accompanying electronic development record of the information created.

The author argues that information technology solutions will play a major part in confirming-by experimental and statistical validation-that bioprocesses may be interchangeable and therefore generic. The bioprocessing ANDA will define both in-house and contract manufacturing.

Freeze pelletization is a new and simple technique for producing spherical pellets for pharmaceutical use.

The authors review current industry practices and regulatory expectations for the aseptic processing of sterile drugs. They compare and outline critical issues in current manufacturing technology and capabilities with regulatory requirements.

Stakeholders consider ways to improve printed patient inserts.

Using dimensionless analytical models, the authors establish the relationships among the essential parameters of a kneading complexation process.

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.

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.
