What is a characteristic of both sublingual and buccal medications?

Sublingual and buccal medications share the characteristic of being absorbed directly into the bloodstream. This is a significant aspect of their administration. When a medication is placed under the tongue (sublingual) or between the gums and the inner lining of the cheek (buccal), it bypasses the digestive system and liver, allowing for rapid absorption into the systemic circulation. This method can lead to quicker therapeutic effects compared to other routes that rely on gastrointestinal absorption.

In contrast, medications that are absorbed into the stomach would have to pass through the digestive system and may be subject to first-pass metabolism, which can reduce their effectiveness. Similarly, slow-release effects are typically associated with specific formulations designed for gradual medication release, rather than the immediate absorption characteristic of sublingual and buccal routes. Finally, suggesting that these modes of delivery are only used for digestive issues is inaccurate; they are often utilized for various types of medications, including those for cardiovascular, pain management, and other systemic needs.
