How are sublingual medications administered?

Sublingual medications are administered by placing them under the tongue. This method allows for rapid absorption into the bloodstream through the mucous membranes in the mouth. The sublingual route is particularly effective because it bypasses the gastrointestinal tract and the liver, allowing the medication to take effect more quickly. It is often used for certain types of medications, such as nitroglycerin for heart conditions, allowing for immediate action when needed. This method contrasts with swallowing, inhaling, or injecting, which involve different routes of administration that do not provide the same rapid onset as the sublingual approach.
