Lidocaine (Lignocaine) inhibits sodium channels involving complex voltage and using dependence[1]. Lidocaine decreases growth, migration and invasion of gastric carcinoma cells via up-regulating miR-145 expression and further inactivation of MEK/ERK and NF-κB signaling pathways. Lidocaine is a commonly used local anesthetics of amide derivative, a drug to treat ventricular arrhythmia and an effective tumor-inhibitor[2].

Lidocaine (Lignocaine) (10 nM; 48 hours) decreases significantly cell proliferation[2]. Lidocaine (1-10 nM; 24-72 hours) inhibits cell viability and achieves the most suppressing effects at the concentration of 10 nM and treatment time 48 hours[2]. Lidocaine (10 nM; 48 hours) increases significantly the apoptotic cell rate[2]. Lidocaine (10 nM; 48 hours) down-regulates Cyclin D1 and up-regulates p21 expression significantly[2].

Lidocaine (Lignocaine) causes completely reversible tail nerve block in rats. Mechanical nociception block produced by lidocaine has slower onset and faster recovery compared with thermal nociception block[3].
