Quality Control Tests for Containers

Quality Control Tests for Containers explain evaluation methods parameters and importance of packaging quality in pharmaceutical products.

Containers are primary packaging materials directly in contact with pharmaceutical formulations.
They must be inert, safe, robust, chemically compatible, and impermeable to ensure drug stability.

Glass Containers (Ampoules, Vials, Bottles)
- Commonly used for parenteral preparations, oral liquids, tablets, and capsules.
- Classified based on hydrolytic resistance:
  - Type I: Borosilicate glass (high resistance)
  - Type II: Treated soda-lime glass (moderate resistance)
  - Type III: Soda-lime glass (lower resistance)
Plastic Containers (Bottles, Sachets, Syringes)
- Made from materials such as:
  - Polyethylene (PE)
  - Polypropylene (PP)
  - Polyethylene terephthalate (PET)
  - Polyvinyl chloride (PVC)
- Commonly used for oral liquids, topical formulations, eye/ear drops, and inhalation devices.
Metal Containers
- Less commonly used for direct contact with pharmaceuticals.
- Often used for aerosols and ointments.
- Quality tests include corrosion resistance and protective lining checks.
