Which of the following drugs is an example of an antihistamine?

Robitussin
Triumeq
Dimetapp
Coumadin

The correct answer is: Dimetapp

Dimetapp is an example of an antihistamine because it contains an active ingredient that blocks the action of histamine, a substance in the body that causes allergic symptoms. Antihistamines are commonly used to treat allergic reactions, such as hay fever, and symptoms like sneezing, runny nose, and itchy eyes. By preventing histamine from binding to its receptors, antihistamines help to alleviate these symptoms. Other drugs listed do not serve the same function. Robitussin is primarily a cough suppressant and expectorant, focusing on alleviating coughing and chest congestion. Triumeq is an antiviral medication used in the treatment of HIV, and Coumadin is an anticoagulant used to prevent blood clots. Each of these medications serves different therapeutic purposes and does not function as an antihistamine.
