What is the appropriate container for dispensing Nitroglycerin sublingual tablets?

  1. In a glass container

  2. In a plastic container

  3. With a cotton plug

  4. With a medicine dropper

The correct answer is: In a glass container

Nitroglycerin sublingual tablets are highly sensitive to moisture and light, making the choice of container crucial for maintaining their stability and effectiveness. Dispensing these tablets in a glass container is the most appropriate option because glass provides a non-permeable barrier that protects the tablets from moisture, which can cause them to degrade. Additionally, glass is preferable because it does not interact with the medications, unlike some plastics that may leach chemicals into the product or change the properties of the drug over time. This ensures that the Nitroglycerin maintains its therapeutic potency when stored properly. The other choices mentioned do not meet the necessary criteria for safely packaging Nitroglycerin. For example, a plastic container could allow moisture in or might not provide the same level of protection from light exposure. Cotton plugs can absorb humidity, potentially affecting the tablets, and while a medicine dropper is inappropriate for solid dosage forms like tablets, it is not suitable for dispensing or storing medications that require specific storage conditions.
