How long sublingual nitroglycerin remain in the system?

Sublingual nitroglycerin is rapidly absorbed into the bloodstream and usually has a duration of action of about 30 minutes to 1 hour. However, its effects can be felt within minutes after administration. The drug is metabolized quickly, and its half-life is approximately 1 to 4 minutes, meaning it is generally cleared from the system within a few hours. Individual factors such as metabolism and overall health can influence this duration.
