Drug Mode of Action ::  

Lidocaine is an amide type local anaesth. It stabilises the neuronal membrane and inhibits Na ion movements, which are necessary for conduction of impulses. In the heart, lidocaine reduces depolarisation of the ventricles during diastole and automaticity in the His-Purkinje system. Duration of action potential and effective refractory period are also reduced. Dextrose is a monosaccharide that is used as a source of calories and water for hydration. It helps to reduce loss of body protein and nitrogen. It also promotes glycogen deposition in the liver.

Drug Interactions ::

May increase serum levels w/ cimetidine and propranolol. Increased risk of cardiac depression w/ ?-blockers and other antiarrhythmics. Additive cardiac effects w/ IV phenytoin. Hypokalaemia caused by acetazolamide, loop diuretics and thiazides may antagonise effect of lidocaine. Dose requirements may be increased w/ long-term use of phenytoin and other enzyme-inducers.
