Lidocaine is a medication which is commonly used as a local analgesic (numbs tissue in a specific area). The average half-life of Lidocaine elimination from the plasma following IV administration is 94 min (first-order kinetics). A dose of Lidocaine was administered via IV, and initial concentration of drug in plasma was 3.63 mcg/ml. Determine the elimination rate constant in s-1 and how long will it take for the drug concentration to drop to 10% of its initial value (in hours).
