Benzocaine HCL works by creating a chemical barrier that halts the build-up of
sodium, which accumulates as the nerve endings are stimulated by pain. When
sodium builds up, electrical signals also build in the nerve endings. These are
eventually transmitted to the brain, which interprets the signals as pain.
Benzocaine is also called amino ethyl benzoate, a colorless or white
orthorhombic needle-like crystals or crystalline powder. Benzocaine
hydrochloride salt is the hydrochloride salt form of the local anesthetic
benzocaine, with the same pharmacological effects of benzocaine and weaker
effect of anesthesia than procaine. Local absorption is slow with lasting
effect. It cannot be used for anesthesia as a result of not being dissolved in
water. It can be used for pain relief and anti-itch. Benzocaine hydrochloride
is usually made into powder or oil paste and used to heal wounds, ulcers,
burns, skin abrasions and hemorrhoids.
Benzocaine hydrochloride readily dissolves in water and bezocaine is only very
slightly soluable in cold water
Local anesthesia of oral and pharyngeal mucous membranes (sore throat, cold
sores, canker sores, toothache, sore gums, denture irritation)
Otic Pain (earache)
Surgical or procedural local anesthesia.
Benzocaine is used as a key ingredient in numerous pharmaceuticals:
Some glycerol-based ear medications for use in removing excess wax as well as
relieving ear conditions such as otitis media and swimmers ear.
Some previous diet products such as Ayds.
