Oxetacaine

Oxetacaine (INN, also known as oxethazaine) is a potent local anesthetic. It is administered orally (usually in combination with an antacid) for the relief of pain associated with peptic ulcer disease or esophagitis. It is also used topically in the management of hemorrhoid pain. Oral oxetacaine preparations are available in several countries, including India, South Africa, Japan and Brazil, but not the United States; oxetacaine was withdrawn from the UK market in 2002.

Unlike most local anesthetics, oxetacaine is active even in strongly acidic conditions.
