Question: 1 / 400

What can epinephrine also be used as?

A strong antiseptic

A mild decongestant

Epinephrine is often utilized as a mild decongestant due to its vasoconstrictive properties. When applied topically, it can reduce swelling and inflammation in the nasal passages, making it easier to breathe. This action is particularly beneficial in treating conditions like nasal congestion associated with allergies or colds.

While epinephrine is best known for its role in emergency situations, such as treating anaphylaxis and cardiac arrest, its decongestant effects are attributed to its ability to stimulate alpha-adrenergic receptors, causing blood vessels to constrict and thus decreasing blood flow and swelling in nasal tissues.

The other options do not align with the established uses of epinephrine. It is not an antiseptic, pain reliever, or antiviral medication. Understanding this context helps clarify why the role of epinephrine as a mild decongestant is significant in clinical practice.
