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 adrakulich@advhttp://adrakulich@advanstar.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.
Sample questions:
• 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?
