Which routes can nitroglycerin be administered?

Nitroglycerin is a versatile medication used primarily to relieve angina pectoris by dilating blood vessels and improving blood flow. It can be administered through multiple routes, which allows it to be effective in various clinical contexts.

Sublingual administration involves placing a tablet under the tongue, where it dissolves and is absorbed directly into the bloodstream. This route is preferred for rapid relief of angina symptoms because it bypasses the digestive system and provides quick action.

Intravenous (IV) administration allows for precise control over dosing and faster onset of action, making it suitable for acute situations in a hospital setting. This method is particularly useful for patients who cannot take medications orally or who require immediate symptom relief.

Transdermal patches provide a continuous release of nitroglycerin over an extended period through the skin. This method is useful for long-term management of angina, allowing for steady levels of the medication in the bloodstream without the need for frequent doses.

Since nitroglycerin can be effectively administered via sublingual, intravenous, and transdermal routes, the correct answer to the question is that all of the provided options are valid routes of administration.
