• 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?
In 2008, adverse affects and deaths linked to Baxter’s blood thinner drug heparin revealed contamination in the heparin supply chain originating from an API manufacturer in China. FDA identified oversulfated chondroitin sulfate (OSCS) in the contaminated heparin. In response to the 2008 heparin situation, the United States Pharmacopeia Convention (USP) has revised the quality standards for heparin. Anita Szajek, PhD, and Tina Morris of USP highlight USP’s revisions to the heparin sodium monograph in the September 2012 issue of PharmTech.
It’s no secret that excipients are not manufactured specifically for pharmaceutical use. In fact, pharma appears pretty low on many excipient makers’ lists of clients. But their importance in drug formulation and in ensuring final product quality has been gaining recognition over the past few years, unfortunately due to some specific events of contamination and adulteration. Because of growing concern in how excipients function and perform, the US Pharmacopeia has developed a new general information chapter on this topic, chapter <1059>. Read more »

This week an interesting report was released about the use of gelatine in medicines. Most of us are comfortable with the use of animal products as ingredients, but for vegetarians or other people that follow restrictive diets it can be an issue. Anybody who falls into this situation should be able to choose whether they will or won’t take a particular product, but the report highlights the fact that many people do not realise that their medicines contain gelatine. In particularly, many vegetarians may unknowingly be prescribed medicines that contain animal derivatives.
Last week, FDA Commissioner Margaret A. Hamburg testified before the House Committee on Energy and Commerce, Subcommittee on Health to outline the agency’s case for supporting the fifth authorization of the Prescription Drug User Fee Act (PDUFA), also known as PDUFA V. In addition to offering her support for PDUFA V, Hamburg also discussed renewal of legislation for promoting pediatric drug testing, the need of FDA to invest in science and innovation, and the agency’s efforts in confronting the continual challenges of globalization. In tackling globalization, a basic question arises: does the United States face a pharmaceutical manufacturing disconnect? Read more »
Personalized medicine, which targets individualized treatment and care based on personal and genetic variations, holds much promise for the pharmaceutical industry. Several pharmaceutical majors continue to invest in this emerging field as evident by Roche’s $5.7-billion bid last week for Illumina, a provider of gene-sequencing tools and related analytics.
