alkalinized lidocaine

Alkalinized lidocaine is a local anesthetic that blocks sodium channels in nerve cell membranes, with alkalinization enhancing its tissue penetration and onset speed.

Alkalinized lidocaine is a local anesthetic that blocks sodium channels in nerve cell membranes, with alkalinization enhancing its tissue penetration and onset speed. Used for Local anesthesia for infiltration, nerve blocks, and topical use.

At a glance

Mechanism of action

Lidocaine works by inhibiting sodium influx through voltage-gated sodium channels, preventing depolarization and action potential propagation in nerve fibers. Alkalinization (raising pH) converts more lidocaine to its non-ionized form, which crosses cell membranes more readily, resulting in faster onset and improved efficacy compared to standard lidocaine formulations.
