Commonly used local anesthetic agents inhibit the VGSCs and also possess a unique membrane stabilizing action through other unknown mechanisms. A study by Mammota et al 15 reported that lignocaine, effectively inhibited the invasive ability of human cancer (HT1080, HOS, and RPMI-7951) cells at concentrations used in surgical operations (5-20 mM). Lidocaine reduced the invasion ability of these cells by partly inhibiting the shedding of HB-EGF from the cell surface and modulation of intracellular Ca2+ concentration contributed to this action. In addition, lidocaine (5-30 mM) infiltrated around the inoculation site, inhibited pulmonary metastases of murine osteosarcoma (LM 8) cells in vivo.
