How are isosorbide denigrate tablets administered to enable them to exhibit faster effect?

Isosorbide dinitrate tablets are typically administered sublingually, which allows for rapid absorption directly into the bloodstream through the mucous membranes in the mouth. This method bypasses the gastrointestinal tract, leading to a quicker onset of action compared to oral ingestion. For optimal effect, the tablet should be placed under the tongue and allowed to dissolve completely without swallowing.
