Delamination of pharmaceutical glass consists in the separation of thin glass flakes from vial surface which start floating into liquid drug.
Delamination can compromise drug efficacy and product shelf life, and cause product recalls.
Factors leading to delamination:
Drug influence
- Drug characteristics: aggressive or sensitive formulation, high pH level, low filling volume
- Drug storage conditions: temperature, time
- Drug production process: vial depyrogenation, terminal sterilization
Glass container influence
- Vial properties and production process: glass tube chemical composition, heat temperature
- Vial surface treatments: sulphuration, internal coating
LDP vials’ optimized manufacturing and dedicated tests make these vials the right solution against delamination phenomenon. Available in EZ-fill® and bulk configurations.
