Nitroglycerin should always be dispensed in a glass container because it is a highly flammable liquid and can react with plastic, causing potential safety hazards. Aminophylline, dopamine, and potassium can all be safely dispensed in plastic containers. Additionally, nitroglycerin is sensitive to light and can cause the medication to deteriorate if stored in anything other than a dark, airtight container. This is why it is important for nitroglycerin to be dispensed in a glass container.
