Exposure to light is a concern with numerous medications due to the potential for photodegradation or other chemical reactions during manufacturing, storage, and administration⁽¹⁾. This may result in potency loss, altered efficacy and adverse biological effects. The sensitivity of a drug to a distinct spectral region of light may vary with its chemical structure, photoreactivity, and nature of the dosage form. The photochemical behavior of a drug provides guidance for handling, packaging, and labeling of drug products. The use of the appropriate containers and packaging material can protect the products from the deleterious effects of light.
