c) to reduce the cost
d) to allow oxidation of drug​

Answer 1

Answer:

a)to prevent the drug from photodegradation

Answer 2

Medicine bottles are made of darkened glass to prevent the drug from photodegradation.

• Photodegradation is referred to as the degradation of a photosensitive molecule caused by the absorption of photons from sunlight involving wavelengths such as infrared radiation and ultraviolet light.
• Generally, dark brown color is used to prevent photodegradation because it has the ability to prevent UV light from degrading the photosensitive contents inside the bottle by photochemical reactions.
• Photodegradation also includes the breaking up of molecules into smaller pieces by photons, the irreversible altering of the shape of a molecule, and oxidation.
