Which option represents a way to take medication that involves placing it under the tongue?

The method that involves placing medication under the tongue is known as sublingual administration. This route allows the medication to dissolve and absorb directly into the bloodstream through the mucous membranes located under the tongue, enabling a rapid onset of action. Sublingual medications bypass the digestive system and liver metabolism, which can enhance their efficacy and speed.

In contrast, a tablet is simply a solid form of medication that can be taken orally, often requiring water to swallow it. A suspension refers to a liquid form of medication in which particles are dispersed in a fluid, typically requiring shaking before use due to potential settling. Topical medications are applied directly onto the skin or mucous membranes, targeting local effects rather than systemic absorption.
