Top Quality Local Anesthetic Raw Powder Benzocaine / Ethyl 4-Aminobenzoate CAS 94-09-7 For Pain Relive
Abstract
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 used as a key ingredient in numerous pharmaceuticals:
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. 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.
Benzocaine mucoadhesive patches have been used in reducing orthodontic pain. In Poland it is included, together with menthol and zinc oxide, in the liquid powder (not to be confused with the liquid face powder) used mainly after mosquito stings. Today’s ready made Pudroderm was once used there as pharmaceutical compound.

Application
Benzocaine is a topical analgesic (meaning it is to be used on the body surface or in the mouth but should not be swallowed) that has a number of different uses in over-the-counter (OTC) medicines. Depending on the dose and form, the active ingredient benzocaine can be used to relieve throat and mouth pain; To alleviate external vaginal itching and burning; To stop pain and itching due to hemorrhoids; Or to relieve minor skin irritations, pain, and itching. Because benzocaine is available in different doses and forms, it is very important to read the Drug Facts label carefully to determine whether the medicine is intended to be used for the symptoms you are experiencing.
Benzocaine can be the only active ingredient in oral treatments that relieve sore throat or address mouth pain caused by cold sores, canker sores, teething, and other issues. It also can be combined with other active ingredients in oral treatments that not only relieve mouth and throat pain, but also protect irritated areas, provide a soothing coating, or relieve dryness.
While oral discomfort treatments containing benzocaine are intended to be used in and around the mouth, there are other topical benzocaine medicines that should only be used externally, or on the outer surface of the body (not near or in the mouth). For example, benzocaine can be found in vaginal medicines that contain more than one external analgesic ingredient or in single active ingredient hemorrhoid treatments. Benzocaine also is available in topical pain relievers that not only relieve skin irritations, pain, and itching, but also contain other active ingredients that kill germs and help prevent infection.
Benzocaine is approved by the U. S. Food and Drug Administration (FDA) and is safe and effective when used according to label directions. Some oral discomfort treatments can be used to temporarily relieve pain due to toothaches; However, these medicines are not intended for long-term treatment. If your toothache pain is severe or lasts for more than seven days, you should talk to your dentist.
Benzocaine may not be contained in all products sold under these brands. Please read the OTC Drug Facts label carefully for active ingredient information for specific products.
