What is the method of drug application referred to as the buccal route?

The buccal route refers to the application of a drug within the cheek or the cavity of the mouth, where the medication can be absorbed through the mucous membranes. This method allows for rapid absorption into the bloodstream while bypassing the digestive system, which can be beneficial for delivering certain medications effectively.

By placing the medication in the buccal pouch, it can dissolve and be directly absorbed into the systemic circulation, providing a quick onset of action. This route is particularly useful for drugs that need to act quickly or for patients who may have difficulty swallowing pills. The other methods described in the options do not pertain to the buccal route, highlighting the distinct characteristics of this method of medication administration.
