5 types of formulation excipients
The article discusses the importance of buffer optimization in stabilizing early development biologic products. It highlights that excipients, which are additives to buffers, play a crucial role in enhancing the long-term stability of biologics.
Key excipients include:
- Adjuvants: Boost immune response, especially in vaccines.
- Surfactants: Reduce surface tension, aiding solubilization of hydrophobic molecules.
- Amino acids: Stabilize protein charges and regulate viscosity.
- Sugars: Provide conformational stability and cryoprotection.
- Polyols: Enhance thermal stability and act as bulking agents.
The text emphasizes the need to screen various excipients for each therapeutic candidate to determine the most effective stabilizers.
