Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a class IB antiarrhythmic agent that blocks voltage-gated sodium channels, inhibiting the inward sodium current, thereby stabilizing cardiac membranes, decreasing automaticity, and increasing the fibrillation threshold. It also acts as a local anesthetic by reversibly blocking nerve impulse propagation.
Lidocaine is an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses.
Lidocaine: Initial IV bolus 1-1.5 mg/kg, then IV infusion 1-4 mg/min. Adjust for arrhythmia suppression.
Apply up to 3 patches topically once daily for up to 12 hours per day. Maximum 3 patches (210 mg lidocaine) per day.
