Product Specification:
Benzocaine 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.
Benzocaine is the precursor materials of Ousso imitation, Orthocaine, procaine. At the same time, it is used as a local anesthetic in medicine, and has analgesic, antipruritic effect, mainly used for wounds, ulcers, mucosal surfaces and hemorrhoids narcotic pain and itch. The ointment can also be used for relieving pain and lubrication to nasopharyngeal catheter and the process of PEEP mirror. Temporary relieve pain and itching skin in the wounds of mild burns, sunburn, trauma and insect bites.

Product Usage:
Lipid soluble surface anaesthetic | Benzocaine is a fat soluble surface anaesthetic. Compared with several other local anesthetics such as lidocaine, tetracaine, etc., the strength of effect is small. Owing to its playing role in mucosal, people feel comfort. It is a fat soluble and strong drug, therefore it is easy to combine with the lipid layer of the mucosa or skin, but not easily go through the human body to produce toxic. |

Benzocaine HCL Description:
Benzocaine HCL 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.
Benzocaine HCl is a salt modification of benzocaine, formed when benzocaine is complexed with
hydrochloric acid. Often, drug salts have enhanced properties compared with the parent compound. For
example, benzocaine hydrochloride is more water soluble than benzocaine, making it more appropriate for oral administration.
Mechanism of Benzocaine 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 neuron membrane, stopping the propagation of the action potential.
Benzocaine Usded for Pain-related Conditions
Local anesthesia of oral and pharyngeal mucous membranes (sore throat, cold sores, mouth ulcers,
toothache, sore gums, denture irritation)
Otic Pain (earache)
Surgical or procedural local anesthesia
