Summary
Injections can contain hazardous insoluble microparticles from glass ampoules. This study reveals factors influencing glass particulate contamination during ampoule opening, offering insights to minimize risks in clinical practice.
Area of Science:
- Pharmaceutical Science
- Materials Science
Context:
- Insoluble microparticles in injections pose health risks.
- Ampoule opening is a critical step where contamination can occur.
- Limited data exists on microparticle generation during ampoule opening.
Purpose:
- Evaluate glass particulate sedimentation over time.
- Assess the impact of swabbing ampoule necks on particle generation.
- Determine the relationship between ampoule inner-diameter and particulate contamination.
- Investigate the effect of different ampoule opening methods.
- Compare particulate contamination between glass and plastic ampoules.
Summary:
- Glass particulate contamination (>2 µm) significantly increases after 60 seconds.
- Swabbing ampoule necks negatively impacts contamination prevention.
- Larger ampoule inner-diameters correlate with increased glass particulate contamination.
- Specific opening methods generate more particles than a novel approach.
- Plastic ampoules exhibit significantly lower microparticle contamination than glass ampoules.
Impact:
- Findings provide crucial data for reducing glass particle contamination in clinical settings.
- Highlights the importance of optimized ampoule opening procedures.
- Suggests material choice (plastic vs. glass) impacts particulate contamination levels.
