Article Synopsis
  • The study focuses on developing extended release (ER) hydrophilic matrix tablets using mirabegron and examines how factors like polymer type, diluent type, and polymer amount influence tablet swelling and erosion behavior.
  • A full factorial design approach and multivariate regression analysis were used to assess how these factors affect critical quality attributes (CQAs) of the formulations.
  • Results showed that the type of polymer can significantly alter swelling and erosion rates, with polyethylene glycol 8000 leading to greater swelling, while polyvinyl alcohol had the highest erosion rate, emphasizing the importance of early-stage screening in drug formulation development.

Extended release formulations play a crucial role in the pharmaceutical industry by maintaining steady plasma levels, reducing side effects, and improving therapeutic efficiency and compliance. One commonly used method to develop extended release formulations is direct compression, which offers several advantages, such as simplicity, time savings, and cost-effectiveness. However, successful direct compression-based extended release formulations require careful assessment and an understanding of the excipients' attributes.

The development of biotechnology-based active pharmaceutical ingredients, such as GLP-1 analogs, brought changes in type 2 diabetes treatment options. For better therapeutic efficiency, these active pharmaceutical ingredients require appropriate administration, without the development of adverse effects or toxicity. Therefore, it is required to develop several quantification methods for GLP-1 analogs products, in order to achieve the therapeutic goals, among which ELISA and HPLC arise.

Introduction: Biotherapeutics are primarily delivered subcutaneously due to better compliance and prolonged rate of absorption compared to other parenteral administration routes. Recent research has allowed for the development of biotherapeutic formulations for subcutaneous delivery that require a lower frequency of administration by increasing drug half-life. Formulations determine shelf-life stability as well as features and transient behaviors that influence stability once implanted in the subcutaneous space.
