What is the function of sublingual tablets in drug absorption?

Sublingual tablets are specifically designed to dissolve under the tongue, allowing for rapid absorption directly into the bloodstream. This bypasses the digestive tract entirely, which can slow down drug absorption and alter the effectiveness of a medication. By being absorbed sublingually, the medication enters systemic circulation more quickly, leading to faster onset of action compared to traditional oral medications, which must dissolve in the stomach and be absorbed later in the gastrointestinal tract. This unique method of delivery is especially useful for certain medications that require quick therapeutic effects or need to avoid degradation by stomach acids.
