Introduction
The rapid spread of COVID-19 created an urgent need for safe, stable, and scalable drug packaging solutions. As researchers explored carbohydrate-based therapeutic candidates and galectin-targeting mechanisms, pharmaceutical packaging became a critical component of product viability. This article highlights key packaging challenges, from glass delamination to protein stability, and discusses modern strategies to ensure safe delivery of COVID-19 drugs.

Understanding the Drug Characteristics
COVID-19 therapeutic research explored galectin-based carbohydrate molecules, known for modulating immune interactions. These compounds often require:
- Stability at room temperature
- Precise pH behavior
- Ethanol washing and aseptic filling
- Compatibility with glass vials, syringes, or cartridges
A detailed analysis of these characteristics is available in the main journal article (DOI link provided below).
Key Packaging Challenges Identified :
Delamination of Glass Containers
Glass delamination where thin flakes detach from a vial’s inner surfaceis a major risk for injectable drugs. High-pH formulations, phosphate buffers, and aggressive sterilization conditions increase this probability.

Main causes include:
- High forming temperatures during vial manufacturing
- High alkali content in glass
- Long storage times and elevated temperatures
- Interaction between Type I borosilicate glass and alkaline formulations
Potential Solutions:
- Surface treatment using ammonium sulfate
- Improved temperature control during glass forming
- Switching to Alumino Silicate or COC/COP vials
- Siliconization of inner vial surfaces
The U.S. Food & Drug Administration (FDA) highlights how inadequate container compatibility can lead to contamination and recalls, stressing the importance of selecting the right glass type for sensitive biologics.
Protein Adsorption on Glass & Rubber Surfaces :
Protein therapeutics are highly sensitive to surface interactions.
Major risks:
- Loss of drug potency
- Aggregation or denaturation
- Adsorption to glass, rubber stoppers, or needle surfaces
Techniques to Reduce Adsorption:
- Silicone oil coating
- PEG/OEG-based coatings
- Use of inert materials like COC/COP
- Incorporation of stabilizers such as carbohydrates or amino acids
The American Association of Pharmaceutical Scientists (AAPS) emphasizes minimizing container–protein interactions to preserve drug efficacy.
Advanced Packaging Technologies:
Siliconization Advantages
- Improved drainage
- Lower plunger movement force
- Reduced surface interaction with proteins
However, excessive silicone leads to droplet formation, which can trigger protein aggregation especially under stress conditions.
Alternatives to Glass Packaging:
COC/COP vials offer:
- No metal ion release
- High transparency
- Low adsorption tendency
- Superior puncture resistance
These materials help maintain stability in high-pH formulations that could otherwise degrade glass.
Challenges in Prefilled Syringes (PFS):
Syringeability Issues
Viscosity directly impacts injection force and user experience. According to the Hagen-Poiseuille relationship, thicker formulations require higher force.
Tungsten & Silicone Oil Interactions
Tungsten from syringe manufacturing may leach into formulations and promote protein aggregation. Silicone oil, although beneficial for lubrication, may cause sub-visible particle formation.
Rubber Components & Adhesives
Leachables from needle shields or adhesives can trigger:
- Impurities
- Protein instability
- Needle clogging

Implications for Global Healthcare
Proper packaging ensures that:
- Drug stability remains intact throughout storage and transport
- Patients receive safe, contaminant-free therapeutic products
- Manufacturing processes comply with regulatory requirements
Organizations like the World Health Organization (WHO) emphasize that safe pharmaceutical packaging is essential for global public health, especially during pandemics.
