Benzocaine
Benzocaine (pronounced ben-ZOE-kane) is a local anesthetic commonly used as a topical pain reliever or in cough drops. It is the active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is also combined with antipyrine to form A/B otic drops to relieve ear pain and remove earwax.
Etymology
The term "Benzocaine" is derived from the key ingredients in its structure: "benzo-" from benzoic acid, and "-caine", a common suffix for alkaloids used as anesthetics.
Uses
Benzocaine is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum.
