What is the duration of action for Lidocaine?

Lidocaine is an antiarrhythmic medication that is commonly used for its effects on heart rhythms and as a local anesthetic. Its duration of action, particularly in the context of managing cardiac issues, typically ranges from 10 to 20 minutes when administered intravenously. This time frame is crucial for healthcare professionals to understand, as it influences dosing regimens and the timing of patient care, especially in emergency situations.

Given this pharmacokinetic profile, the choice indicating a duration of action of 10 to 20 minutes accurately reflects the expected therapeutic window for Lidocaine. Understanding this helps in planning and adjusting treatment protocols effectively when dealing with arrhythmias or during procedural sedation.
