Lidocaine is a local anesthetic and antiarrhythmic drug. It is a derivative of cocaine, but there is no component of cocaine that produces hallucination and addiction. Lidocaine hydrochloride is a white crystalline powder, which is very slightly dissolved in water and has the same toxicity as procaine, but the local anesthesia effect is strong and lasting, with good surface penetration, and can be injected or used as surface anesthesia. Lidocaine is a very good local anesthetic. It generally takes effect one to three minutes after application, and the effect lasts for one to three hours. It is used to treat oral ulcer.
