Why are sublingual and buccal medications rapidly absorbed?
They are metabolized in the liver.
Their action is located in the mouth.
These drugs pass directly into systemic circulation.
Blood flow is diminished in these sites.
The Correct Answer is C
Sublingual and buccal medications are rapidly absorbed because they are placed under the tongue or between the cheek and gum, where they dissolve and are absorbed directly into the bloodstream through the mucous membranes in the mouth. This allows for rapid absorption and bypasses the liver’s first-pass metabolism.

However, it is the drug of choice for the treatment of Trichomoniasis vaginalis, a common sexually transmited infection caused by a protozoan parasite. Therefore, the nurse should include in the teaching that metronidazole is indicated for the treatment of Trichomoniasis vaginalis.
