Lidocaine 1%/Epi 1:200000
Lidocaine blocks sodium channels in nerve cell membranes to produce local anesthesia, while epinephrine causes vasoconstriction to prolong the anesthetic effect and reduce systemic absorption.
Lidocaine blocks sodium channels in nerve cell membranes to produce local anesthesia, while epinephrine causes vasoconstriction to prolong the anesthetic effect and reduce systemic absorption. Used for Local anesthesia for infiltration, nerve blocks, and topical procedures, Dental anesthesia, Minor surgical procedures requiring local anesthesia.

Mechanism of action
Lidocaine is a local anesthetic that reversibly inhibits sodium influx into nerve fibers, preventing depolarization and action potential propagation. The addition of epinephrine (1:200,000 concentration) acts as a vasconstrictor on local blood vessels, which slows the systemic absorption of lidocaine, extends its duration of action at the injection site, and reduces the risk of systemic toxicity.
