Substance Name: Lidocaine [USP:INN:BAN:JAN]
RN: 137-58-6
UNII: 98PI200987
InChIKey: NNJVILVZKWQKPM-UHFFFAOYSA-N

Note

  • A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of procaine but its duration of action is shorter than that of bupivacaine or prilocaine.
