Which route of administration is associated with using medicated tablets for rapid absorption through the mouth?

The sublingual route of administration is associated with the use of medicated tablets for rapid absorption through the mouth because it involves placing the drug under the tongue, where it dissolves and is absorbed directly into the bloodstream through the tissue there. This method bypasses the gastrointestinal tract and the first-pass metabolism in the liver, allowing for a quicker onset of action compared to other routes.

In contrast, the oral route involves swallowing medication, which needs to go through the digestive system before entering the bloodstream, often leading to slower absorption. Topical administration refers to medications applied directly onto the skin for localized effects and does not facilitate systemic absorption in the same manner as sublingual administration. Intravenous administration delivers medication directly into the bloodstream, but it does not involve tablets or oral absorption processes, making it unrelated to the question regarding rapid absorption specifically through the mouth.
