Sublingual Tablet
舌下錠 (Zekka-jō)
A tablet placed under the tongue where it dissolves and is absorbed rapidly into the bloodstream through the sublingual mucosa. This route avoids first-pass metabolism in the liver, allowing faster and more complete absorption than swallowed tablets. In Japan, sublingual tablets are used for nitroglycerine (chest pain emergency), allergy immunotherapy (house dust mite and cedar pollen), and some hormonal therapies. Do not swallow or chew sublingual tablets.
Sublingual immunotherapy (SLIT) tablets for hay fever and dust mite allergy have become increasingly available in Japan since 2014 as an alternative to injection immunotherapy.
