Protection of Light Sensitive Products
A lot of pharmaceutical products are light sensitive those degrade when directly exposed to the light. Some impurities may develop during this degradation and product may fail during the quality control analysis. These impurities may harm the patient’s health.
These light-sensitive APIs and pharmaceutical products should be protected from light during processing and distribution. Light sensitive products may be affected by sunlight or artificial light.

Light for light sensitive products
Light induces the interaction between the molecules of the compound that leads to the formation of a new compound known as an impurity.
Light has energy that can activate the molecules of the drug. Photodegradation usually occurs due to absorption of short wavelength light between 500 and 300 nm. Visible blue, violet and ultraviolet light cause this degradation. For example, ofloxacin remains 80% when exposed to direct light for a period of 240 hours.
