Pharmacology and toxicologyThis product is an amide local anesthetic. After blood absorption or intravenous administration, it has obvious excitation and inhibition biphasic effect on the central nervous system, and there can be no precursor excitement, when the blood concentration is low, analgesia and drowsiness, and the pain threshold is increased; With the increase of dose, the effect or toxicity increases, and there is an anticonvulsant effect at the concentration of subtoxic blood drugs; When the blood concentration exceeds 5 mg·mL-1, convulsions can occur.
