Which of the following medications is used to treat ear conditions?

Auralgan is a medication specifically formulated to treat ear conditions, particularly pain associated with ear infections. It often contains a combination of an analgesic (pain reliever) and a local anesthetic which helps to alleviate pain in the ear. Auralgan works directly at the site of discomfort, making it particularly effective for conditions like otitis media (middle ear infection) or other painful ear disorders.

The other options do not serve this specific purpose. Coumadin, for instance, is an anticoagulant used primarily to prevent blood clots, while Metamucil is a fiber supplement intended to aid in constipation and digestive health. Betagen is an antibiotic used for skin conditions, not ear problems. Each of these medications has a distinct application that does not involve the treatment of ear conditions, which reinforces why Auralgan is the correct choice.
