Sublingual (SL) tablets are placed under the tongue.

• A. Enteric-Coated tablets
• B. Film-Coated tablets
• C. Oral disintegrating tablets
• D. Sublingual tablets

Answer: (D)

Sublingual tablets are placed under the tongue to allow rapid absorption through the rich vascular layer there, delivering the drug quickly into the bloodstream while bypassing the liver’s first-pass metabolism. This direct route explains why they are chosen for medicines that need a fast onset or would be degraded if swallowed and processed through the digestive system. The other tablet types have different purposes: enteric-coated tablets are designed to resist stomach acid and release the drug in the intestine, film-coated tablets are mainly coated for taste or protection but are swallowed, and oral disintegrating tablets are meant to dissolve in the mouth (often in saliva) rather than specifically under the tongue. Therefore, the description fits sublingual tablets.
