Lidocaine hydrochloride (Lignocaine hydrochloride) inhibits sodium channels involving complex voltage and using dependence^[1]. Lidocaine hydrochloride 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 hydrochloride is an amide derivative and a drug to treat ventricular arrhythmia and an effective tumor-inhibitor^[2].

Lidocaine hydrochloride (Lignocaine hydrochloride) (10 nM; 48 hours) decreases significantly cell proliferation^[2].
Lidocaine hydrochloride (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 hydrochloride (10 nM; 48 hours) increases significantly the apoptotic cell rate^[2].
Lidocaine hydrochloride (10 nM; 48 hours) down-regulates Cyclin D1 and up-regulates p21 expression significantly^[2].
