摘要

Lignocaine is an essential drug on World Health Organisation essential drug list,considered efficacious,safe and cost-effective for any health-care system.Despite its ubiquitous use in medicine and surgery,there are few detailed reviews of its pharmacokinetics and pharmacodynamics.Being an amide-type local anesthetic and Class 1b antiarrhythmic,lignocaine is most frequently used clinically for its anesthetic and antiarrhythmic benefits.However,lignocaine has important antinociceptive,immuno-modulating,and antiinflammatory properties.Information pertaining to the pharmacokinetics and pharmacodynamics of lignocaine was examined by performing a literature search of PubMed,Embase and MEDLINE(via Ovid),pharmacology textbooks and online sources.We present a focused synopsis of lignocaine’s pharmacological composition,indications for use and mechanisms of action,focusing on its anti-inflammatory,immuno-modulating and analgesia effects.In addition we review the dosing regimes and infusion kinetics of lignocaine in the clinical setting.Finally,we review the evidence for ligocaine’s modulation of the inflammatory response during major surgery and its specific effects on cancer recurrence.These indirect effects of local anesthetics in tumor development may stem from the reduction of neuroendocrine responses to the stress response elicited by major surgery and tissue damage,enhanced preservation of immune-competence,in addition to opioid-sparing effects of modulating tumor growth.
