Benzocaine

Description
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.

Basic Info

 Effect: The local anesthetic effect of benzocaine is weaker than that of procaine, it cannot be used for infiltration, and local absorption is slow and lasting. It is hydrolyzed into p-aminobenzoic acid. It has no irritation and toxicity when the normal concentration is 2%-10%. The toxicity is only 5% of cocaine or 1Chemicalbook0%. The maximum safe amount for topical use is 5g or 25mL of 20% solution. Inhibits the conduction of nerve impulses from sensory nerve endings and makes the sense of taste dull. The structure is similar to procaine, so it absorbs slowly and has a long-lasting anesthetic effect.
