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.

Answer and Explanation

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.

A. I can take an over-the-counter antihistamine for allergies when I’m taking this drug B. I should take this medication when my spasms are bad. C. My muscle strength should improve a lot in 2 to 3 days D. I need to apply a sunscreen when I go outside

Correct Answer is D

Explanation

The correct answer is choice d. I need to apply a sunscreen when I go outside.

Choice A rationale:

Taking over-the-counter antihistamines with dantrolene is not recommended because both can cause drowsiness and increase the risk of side effects.

Choice B rationale:

Dantrolene should be taken regularly as prescribed, not just when spasms are bad, to maintain consistent therapeutic levels and effectiveness.

Choice C rationale:

Muscle strength improvement with dantrolene may take longer than 2 to 3 days. It typically requires a few weeks to see significant benefits.

Choice D rationale:

Dantrolene can cause photosensitivity, making the skin more sensitive to sunlight. Therefore, applying sunscreen when going outside is important to prevent sunburn.
