Benzocaine is a fat-soluble topical anesthetic that does not cause discomfort due to anesthesia when it acts on the mucous membranes. It is a kind of drug with strong fat solubility, so it is easy to combine with the lipid layer of mucous membrane or skin, but it is not easy to penetrate into the human body to produce toxicity. Benzoka is also used as a local anesthetic in medicine, and has analgesic and antipruritic effects. It is also effective for toothache, sore throat, mouth ulcers, various hemorrhoids, anal fissures, genital itching, and as a male genital desensitizer to slow ejaculation. Or as an anesthetic lubricant for catheters and endoscopic tubes. | |
