Why is it important to store nitroglycerin away from heat and moisture?

Storing nitroglycerin away from heat and moisture is crucial to maintain its stability and potency. Nitroglycerin is a sensitive compound that can degrade when exposed to environmental factors such as elevated temperatures and humidity. Over time, these conditions can lead to a loss of effectiveness, as the medication may break down into inactive metabolites. This stability is essential for ensuring that patients receive the appropriate dose of nitroglycerin during an angina attack. Proper storage conditions help maintain the integrity of the drug and ensure that it works as intended when needed.
