Drug Development

Poly(vinyl acetate) phthalate-based and acrylic-based enteric coating systems are evaluated for their performance on acetylsalicylic acid tablets in areas such as acid resistance and coated-tablet stability.

Two types of hydrogels used in parenteral protein-delivery systems offer opportunities for achieving a variety of prolonged- and delayed-release patterns.

Insulin is one of the most popular proteins to be studied for oral delivery. The authors review the current status of the development strategies of insulin drug delivery systems, the various challenges associated with these systems, and how these challenges may be overcome.

The author proposes a strategy for achieving a successful partnership with Big Pharma on the basis of forming a relationship with the company, deliberately managing the alliance, and clearly defining roles and responsibilities.

The author assesses the compressibility of Plasdone S- 630 copovidone-based tablet formulations using roller-compaction and direct-compression processes.

This comparative study suggests that pregelatinized starches are superior to natural starches in terms of improving the plastic deformation in tablet formulations during compression.

This study attempts to determine the combination of excipients found in commercial ASA products that would be suitable for use in an aqueous enteric film&#173coating process.

Both academia and industry have been encouraged to generate quick&#173dissolving dosage forms as the demand for fast&#173disintegrating tablets and capsules has steadily increased.

To aid the fomulation scientist in selecting the optimal excipients for the preparation of vaginal products, the authors have compiled a list of all presently available vaginal excipients, including their functional categories and regulatory status.

Careful planning and decision-making can circumvent possible delays in technology transfers.

USP ensures the microbiological quality of products by way of the development, proposal, and acceptance of general information chapters.

Developments in technology and increased industry standards have changed the regulation, quality control, and perception of excipients in the past 25 years.

Appropriate sampling procedures, proper preparation, and correct instrumental parameters may yield differing, but correct, results.

Using formulations containing various types of lactose and dibasic calcium phosphate, the authors investigated the effects of lubricant level, lubrication time, and compression speed on tablet weight, hardness, and friability.

Special considerations and cautions must be adhered to when designing virus safety studies and developing appropriate virus contamination control programs.

Evolution of an existing drug molecule from a conventional form to a novel delivery system can significantly improve its performance in terms of patient compliance, safety, and efficacy. These days,drug delivery companies are engaged in the development of multiple platform technologies to get competitive advantage, extend patent life, and increase market share of their products.
