How should nitroglycerin tablets be stored?

• A. In a clear bottle
• B. Refrigerated
• C. Original packaging and no sun
• D. Exposed to heat

Answer: (C)

Nitroglycerin tablets are very sensitive to light and heat, so protecting them from these elements preserves potency. Storing them in the original packaging provides a built-in shield against light and minimizes air exposure, and keeping them out of sunlight prevents accelerated breakdown. A clear bottle would let light get in and degrade the tablets. Refrigerating isn’t ideal because temperature changes and moisture can affect stability, and exposing the bottle to heat would also hasten deterioration. So, keeping them in their original packaging and away from sun best maintains their effectiveness.
