Chemical properties

Benzocaine is the ethyl ester of p-aminobenzoic acid (PABA). It can be prepared from PABA and ethanol[1] by Fischer esterification or via the reduction of ethyl p-nitrobenzoate. Benzocaine is sparingly soluble in water; it is more soluble in dilute acids and very soluble in ethanol, chloroform and ethyl ether. The melting point of benzocaine is 88-90 °C,[2] and the boiling point is about 310 °C.[3] The density of benzocaine is 1.17 g/cm3.
History

Benzocaine was first synthesized in 1890 by the German chemist Eduard Ritsert (1859-1946),[4] in the town of Eberbach[5] and introduced to the market in 1902 under the name "Anästhesin".[6][7]
Mechanism of action

Pain is caused by the stimulation of free nerve endings. When the nerve endings are stimulated, sodium enters the neuron, causing depolarization of the nerve and subsequent initiation of an action potential. The action potential is propagated down the nerve toward the central nervous system, which interprets this as pain. Benzocaine acts to inhibit the voltage-dependent sodium channels (VDSCs) on the nerve membrane, stopping the propagation of the action potential.
Side effects

Over-application of oral anesthetics such as benzocaine can increase the risk of pulmonary aspiration by relaxing the gag-reflex and allowing regurgitated stomach contents or oral secretions to enter the airway. Applying an oral anesthetic and consuming beverages before going to bed can be particularly hazardous. The oral use of benzocaine products has been found to be a cause of methemoglobinemia, a disorder in which the amount of oxygen carried by the blood is greatly reduced. This side effect is most common in children under 2 years of age.[8]
Allergic reactions occur with ester local anaesthetics such as benzocaine because of the PABA core structure.[citation needed]
Other uses

Benzocaine is used as a key ingredient in numerous pharmaceuticals:
Over the counter throat lozenges such as Anbesol and Cepacol.
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.
Some condoms designed to prevent premature ejaculation. Benzocaine largely inhibits sensitivity on the penis, and can allow for an erection to be maintained longer (in a continuous act) by delaying ejaculation. Conversely, an erection will also fade faster if stimulus is interrupted.[9][10]
Benzocaine is used in abalone aquaculture. The strong muscular foot which the abalone use to hold on to the rocks in the wild makes handling the animals difficult. Abalone farmers use benzocaine to mildly anaesthetise them, resulting in the animals loosening their tight grip on the substrate. This enables the farmers to more easily remove them and move them around the farm.[citation needed]
Benzocaine is commonly found, particularly in Britain, as an impurity in street cocaine. Whilst giving a numbing effect similar to cocaine on users' gums it does not actually produce the effects of cocaine.[11]

Treating pain from mouth and gum irritations (eg, canker sores). It may also be used for other conditions as determined by your doctor.
