FDA’s quality-by-design (QbD) initiative is a systematic approach to designing and developing pharmaceutical formulations and manufacturing processes to ensure predefined product quality. Understanding the critical quality attributes of the ingredients in a formulation, including excipients, and the critical process parameters in the manufacturing process of the finished drug product is crucial for successfully implementing QbD. Pharmaceutical Technology will be holding a live webcast on Thursday May 23 from 10:00 AM to 11:00 AM EST to examine the regulatory and technical considerations in implementing QbD for coatings in modified-release formulations, including strategies to mitigate the risks associated with alcohol-induced dose-dumping and the application of alcohol-resistant coatings.

The challenge of developing orally inhaled nasal drug products (OINDPs) is complicated by the interplay between drug-delivery devices and formulation. An article in the February 2013 issues of Pharmaceutical Technology and Pharmaceutical Technology Europe, “Improving Inhaled Product Testing: Methods for obtaining better in vitro-in vivo relationships,” discussed testing equipment and techniques. PharmTech recently interviewed the author, Mark Copley, sales director at Copley Scientific, to gain further insight into the importance of this topic. Read more »
Research into hot melt extrusion (HME) as a solution to improve solubility continues to expand with a partnership between Encap Drug Delivery, a contract development and manufacturing organization in the UK, and the School of Pharmacy at the Queen’s University Belfast (QUB), announced in a press release this week.

Pharmaceutical Technology and Patheon are partnering to provide you—our readers—with CMC advice from some of the leading formulation scientists and pharmaceutical manufacturing experts in the world. To get started, we need to know what plagues your CMC strategies and daily work. Email your questions directly to Editorial Director Angie Drakulich at email@example.com. (*Note: We will keep your name and company affiliation anonymous.)
Answers will be provided by the Patheon Certified Consultants team beginning in the January 2013 print and online editions of PharmTech. These experts have collectively brought more than 200 pharmaceutical products to market, including some of the world’s largest blockbusters.
• I have a BCS Class II compound for which amorphous solubility is easily sustained, but I can’t get the compound to rapidly dissolve. What are some solutions, particularly with respect to excipient selection?
• I have a compound that is non-ionizable and does not form a stable salt. Are co-crystals my best option and what are the key criteria in identifying a suitable co-crystal?
• I am having trouble maintaining product stability when scaling up a lyophilization process. What are the likely factors causing the problem?
Researchers are trying to find better, cheaper ways to produce biodegradable and bio-based polymers. Although one of the main drivers for this research is to compete with fossil-fuel-based polymers in large-volume, consumer plastics applications, medical applications, such as microcapsules for drug delivery, may also benefit. While it seems odd, the researchers found that waste oil from cooking fried food can be used as a raw material in the polymer production process. Read more »
Innovation is the cornerstone of the pharmaceutical industry. The challenge to innovation not only entails identifying drugs with clinical efficacy but also in being able to produce and deliver the desired drug compound. An upcoming Pharmaceutical Technology webcast, Omega-3 Innovations in Pharmaceutical and Diagnostic Markets, will examine the latest developments for omega-3 prescription drug products, their regulatory status, and recent advances in softgel drug-delivery technologies for omega-3 products.

Improving drug delivery is an important consideration in new drug development and in managing the product life cycle of existing drugs. Delivery mechanisms that can improve patient compliance, facilitate administration, and target delivery of an active are crucial goals. Drugs that are delivered topically provide an opportunity to realize these objectives, and an upcoming webcast on Dec. 7th by Pharmaceutical Technology gains insight from leading industry experts on how to optimize topical drug formulations and manufacturing.
