Which medication is an expectorant commonly used to loosen mucus in respiratory infections?

Explanation:
Expectorants loosen and thin mucus to make coughing more productive and help clear chest congestion during respiratory infections. Mucinex contains guaifenesin, which thin mucus so it can be expelled more easily from the airways. The other medications don’t have this mucus-thinning effect: ibuprofen is a pain/fever reducer and anti-inflammatory; acetaminophen is also a pain/fever reducer; diphenhydramine is an antihistamine that dries secretions rather than thinning them.
