What are advantages and disadvantages of nitroglycerin tablets?

Nitroglycerin tablets are effective for quickly relieving angina (chest pain) by dilating blood vessels, improving blood flow to the heart. An advantage is their rapid onset of action, providing relief within minutes. However, disadvantages include potential side effects such as headaches, dizziness, and low blood pressure, and they may not be suitable for everyone, particularly those with certain medical conditions or who are taking specific medications. Additionally, proper storage and handling are essential, as nitroglycerin is sensitive to light and heat.
