Lidocaine Base / Hydrochloride

What is Lidocaine Base / Hydrochloride?

Lidocaine, available as a base or hydrochloride salt, is a fast-acting local anesthetic and antiarrhythmic agent. It works by blocking sodium channels in nerve cells, which prevents pain signals from reaching the brain. Lidocaine is widely used in dental procedures, minor surgeries, topical pain relief, and also as an intravenous drug for certain cardiac arrhythmias. It is found in creams, gels, patches, injections, and sprays.
