High purity polysorbates: One of the keys to stability in biopharmaceuticals
Polysorbates are essential in biopharmaceuticals, enhancing solubility, improving bioavailability, and protecting therapeutic proteins from denaturation and aggregation. These functions extend product shelf life and ensure the safety and efficacy of drug formulations. Widely used in small molecule and biotherapeutic formulations, where patient safety is paramount, polysorbates’ reliable performance is well-documented.
Polysorbates have an established safety profile and versatility, making them staples in the formulation of biologic drug products. However, impurities in polysorbates can significantly impact formulation quality. Free fatty acids can cause particle formation, while peroxide and aldehyde impurities can oxidise residues like methionine and tryptophan, leading to protein API degradation. High-purity polysorbates are crucial to prevent these issues and maintain drug stability. Purity is vital because impurities can lead to API degradation, reduced efficacy, and potential safety concerns for patients.
The synthesis and characterisation of polysorbates involve complex processes. The choice of raw materials, processing conditions, and final isolation steps all contribute to the quality of the finished drug product. Advanced analytical techniques help fully characterise the materials, providing confidence in their performance in drug formulations.
Surfactants in Biopharmaceutical Development delves into the critical importance of maintaining high-purity polysorbates. The book thoroughly examines their synthesis, characterisation, and degradation, highlighting how these factors influence the stability of monoclonal antibody (mAb) formulations and APIs. The detailed exploration of these processes helps pharmaceutical professionals understand the complex chemistry involved and the importance of maintaining high standards of purity to ensure product efficacy and safety.
