Study Notes

Sterile Product Preparation

A carefully trained pharmacist or technician with proper training in aseptic technique and sterile product information is necessary.

Factors Affecting Adsorption

The amount of adsorption depends on several factors, including:
- Concentration
- Surface area of the tubing

Sealed Ampoules Testing

Sealed ampoules by fusion should be tested to ensure that a hermetic seal was obtained.
The testing process involves:
- Immersing ampoules in a dye solution with their necks down in a vacuum desiccator.

Anatomy of the Eye

The choroid is the second layer of the eye, located between the sclera and the retina.
The choroid contains the blood vessels that provide nourishment to the outer layers of the retina.

Factors Influencing pH

pH is influenced by several factors, including:
- Product degradation
- Diffusion of gases through the closure
- Effect of gases in the product
- Container and stopper effects

pH Buffering Agents

Weak base and salt of a weak base or weak acid and salt of a weak acid are normally used as pH buffering agents, such as:
- Acetates
- Citrates
- Phosphates
