Novel Vial-Inner-Surface Treatment Technology Improves Chemical Durability and Vial-Inner-Surface Uniformity to Reduce Drug Adsorption on the Vial.

The pharmaceutical industry relies heavily on the safe and efficient packaging of drugs and injection glass vials play a pivotal role in this regard. Ensuring the quality and consistency of these vials is essential for safeguarding the potency of pharmaceutical formulations. In this study, the recent breakthroughs achieved in the manufacturing of injection glass vials by implementing advanced surface-processing technologies were examined. We developed potential injection glass vials using the novel vial-inner-surface treatment (VIST) technology to homogenize the inner surface of the vials. Compared with common vials, the elution of alkali contents and conductivity of these injection glass vials were reduced because of the VIST technology, resulting in the formation of smooth and homogeneous inner surfaces. In addition, drug adsorption onto the inner surface of the VIST vials was considerably lowered than that onto common vials. These results suggest that VIST vials are of excellent quality and could become the standard injection glass vials.
