CAS 94-09-7 99% High Purity Pain Killer Benzocaine Pharmaceutical Raw Materials

 
Description:
 

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. Ears are used to reduce the pain and itching of acute congestive, concentrated otitis, swimming, and external use. Also it is effective to toothache, sore throat, oral ulcers, hemorrhoids, anal fissure, vulva Sao. As Male Genital Desensitizer make ejaculation slow.

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.

Applications:
 
Benzocaine can be prepared by esterification using 4-aminobenzoic acid and ethanol. It can also be prepared by reduction of ethyl 4-nitrobenzoate to the amine.
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.
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.
Benzocaine is commonly found, particularly in Britain, as an impurity in street cocaine and also as a bulking agent in "legal highs". Whilst giving a numbing effect similar to cocaine on users' gums it does not actually produce the effects of cocaine. Also benzocaine can and has been mistaken for a false positive for cocaine.
Benzocaine was used in synthesis of Leteprinim.
 
Side effects:
 
Benzocaine is generally well-tolerated and non-toxic when applied topically as recommended.

However, there have been reports of serious, life-threatening adverse effects (e.g., seizures, coma, irregular heart beat, respiratory depression) with over-application of topical products or when applying topical products that contain high concentrations of benzocaine to the skin.

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 topical use of higher concentration (14-20%) benzocaine spray products applied to the mouth or mucous membranes 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. As a result, the FDA has stated that benzocaine products should not be used in children under 2 years of age, unless directed by and supervised by a healthcare professional. Symptoms of methemoglobinemia usually occur within minutes to hours of applying benzocaine, and can occur upon the first-time use or after additional use.

Benzocaine may cause allergic reactions.
