Antipyrine and benzocaine ear drops is a medication for the treatment of ear pain caused by otitis media. It combines antipyrine, a pain reliever, benzocaine, a numbing agent to treat ear pain, and Hydroxyquinoline Sulfate, an antiseptic. It is sold as Auralgan, Aurodex, Auroto,[1] among other brands, and is abbreviated as A/B otic drops.

Ingredients[edit]

Each 1 ml of A/B otic drops contains:[2]

  • Antipyrine 54 mg
  • Benzocaine 14 mg
  • Glycerin and Hydroxyquinoline Sulfate USP

Indications[edit]

A/B otic drops is indicated for ear pain caused by otitis media. It is used every 2–3 hours as needed for pain.[2]

A/B otic drops is also indicated for the removal of excessive or impacted cerumen. To clear cerumen, it is used 3 times a day for 2–3 days.[2]

Clinical pharmacology[edit]

A/B otic drops are effective because antipyrine reduces pain and inflammation and benzocaine numbs the ear.

Reformulation[edit]

In 2008, Auralgan was reformulated to include acetic acid and U-polycosanol 410, in addition to antipyrine and benzocaine. Due to this reformulation, pharmacies could no longer substitute the generic antipyrine/benzocaine drops for a prescription written as "Auralgan". The price for the new formulation was roughly $150.00 compared to the generic price of $2.00.[3]
