Benzocaine Hydrochloride outline

What is benzocaine topical?

Benzocaine is a local anesthetic. It is the active ingredient in many over-the-counter (OTC) products used to relieve pain in the mouth and gums from a variety of conditions. OTC benzocaine products come in the form of gels, pulvérisation, liquids, and lozenges.

Benzocaine topical 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, nez, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum.

Application

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.

La benzocaïne est utilisée comme ingrédient clé dans de nombreux produits pharmaceutiques:Over the counter throat lozenges such as 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. La benzocaïne inhibe largement la sensibilité sur le pénis, et peut permettre à une érection d'être maintenue plus longtemps (dans un acte continu) en retardant l'éjaculation. Inversement, an erection will also fade faster if stimulus is interrupted.Benzocaine mucoadhesive patches have been used in reducing orthodontic pain.
