Further studies are in progress to assess the mechanism of the clinical effect on dysmenorrhoea as well as the optimal dosage and therapy

intervals. This study supports the hypothesis that pertubation with 10 mg of lignocaine is safe and indicates that it might be possible to try a higher dose to further improve the clinical effect on pain. 5 Conclusions Lignocaine pertubated through the fallopian tubes reaches the peritoneal cavity and diffuses through the peritoneum into the blood circulation. The serum levels of lignocaine following pertubation of 10 mg lignocaine hydrochloride are detectable but low. IWP-2 price Pertubation with lignocaine is safe and produces no lignocaine-related adverse events.
