• The EU's Ban On TiO2 In Food May Impact Pharma. Here's What You Should Know.

    Titanium dioxide (TiO2) is used as a food additive and OSD pharmaceutical excipient. In 2020, the European Food Safety Authority noted data gaps regarding particle size, which can affect its toxicological properties, so the European Commission banned it as a food additive. Here's how this could impact pharma.

  • Osmotic Controlled Release Oral Drug Delivery: A Closer Look

    Osmotic controlled release drug delivery is not often spoken about, but it is a useful oral drug formulation technology. This article shares the mechanisms of the elements of oral dosage, including the semi-permeable membrane, pore-forming agents, and more, as well as advantages and applications of this type of drug delivery.

  • 4 Strategies To Formulate Poorly Soluble APIs

    One of the toughest challenges facing small molecule drug development today is poor solubility of the API. No single technique has universal application, so several strategies exist. This article examines four notable strategies.

  • 4 Tips To Leverage Your Ingredient Supplier For Faster Formulation

    Speed to formulation plays a critical role in recouping the investment for a new drug. Many ingredient suppliers have an experienced analytical group and material scientist group, and drug developers should reach out and leverage that expertise with these four strategies.

  • 3 Action Items For The US Bio/Pharma Industry To Mitigate Supply Vulnerabilities

    The United States’ reliance on foreign manufacturers of API has been a known fact for several years. We can mitigate our supply vulnerabilities, but bio/pharma companies and the FDA both have roles to fill in this need.

  • Addressing 3 Challenges Of Developing Or Using A New Excipient

    As the world discovers new molecular entities, new solutions for and innovation of excipients are more critical than ever. However, they are often overlooked. Let’s look at how to address three key challenges: risk aversion, an inconsistent feedback loop between pharma companies and excipient suppliers, and the current lack of regulatory body-backed innovation programs.
