Lidocaine is a local anesthetic, also known as Xylocaine, in recent years it has been replaced procaine, widely used in local infiltration anesthesia in cosmetic plastic surgery, it can block the nerve excitability and conduction by inhibiting the sodium channels of nerve cell membrane. The fat soluble and protein binding rate of lidocaine is higher than procaine, its cell penetrating ability is strong, fast onset, long duration of action, the interaction strength is 4 times of procaine.
Lidocaine is a widely used local anesthetic and antiarrhythmic agent produced via chemical synthesis involving 2,6-dimethylaniline. Its molecular formula is C14H22N2O with CAS No. 137-58-6.
Strictly limit dosage to prevent systemic toxicity; store in cool, dry conditions away from direct light to maintain stability.
