Nitroglycerin is typically administered under the tongue, a method known as sublingual administration. This route is chosen because it allows for the medication to be absorbed quickly into the bloodstream through the mucous membranes in the mouth, providing rapid relief from angina attacks or chest pain. The rich blood supply in the area facilitates swift action, which is critical in treating conditions such as angina pectoris where immediate relief is desired.

When considering other administration methods, such as intravenously, orally, or topically, they are not the preferred method for immediate relief of angina. Intravenous administration may be used in a hospital setting for severe cases but is not the standard practice for routine management. Oral administration would typically lead to slower absorption and may not provide rapid relief, while topical applications are generally used for sustained release of the medication rather than for immediate effects. Thus, sublingual administration is specifically indicated for its quick onset of action in managing acute chest pain effectively.
