Local anesthetic. Lidocaine inhibits nerve conduction via sodium channel blockade. Class-1 antiarrhythmic. Decreases Phase 0 depolarization without affecting conduction. After systemic administration lidocaine is metabolized to monoethylglycinexylidide (MEGX), which also has antiarrhythmic properties. Lidocaine also has analgesic properties after systemic administration. During intravenous infusion, it may decrease pain response. In horses, infusions of lidocaine have decreased postoperative ileus either through a direct effect, via suppression of painful stimuli, or through anti-inflammatory
Lidocaine is used commonly as a local anesthetic and for acute treatment of ventricular arrhythmias. Lidocaine should be used cautiously for treating supraventricular arrhythmias because it may increase cardiac conduction. Lidocaine also is used for pain management. It has been administered as a constant rate infusion (CRI) in animals, especially in postsurgical patients. Lidocaine has been combined with other analgesics, which may be synergistic and allow lower doses of each individual component. One example of a combination is MLK, which is morphine (or fentanyl), lidocaine, and ketamine. Li
