A local anesthetic that works by stopping nerves from sending pain signals.
US a drug used as a local anaesthetic.
Local anesthetic agent used topically on the skin and mucous membranes and parenterally to treat cardiac arrhythmia. Adverse effects from systemic use include cardiac arrest and central nervous system disturbances; from topical use, hypersensitivity reactions.
A local anaesthetic given by injection, previously called lignocaine. It is also used in the treatment of certain disorders of cardiac rhythm known as ventricular arrhythmias, which may be particularly dangerous following a coronary thrombosis.
A localized anesthetic employed to desensitize tissues before minor surgical interventions. Lidocaine is also utilized for nerve blocks. This medication is often administered through injections, but it can also be applied topically on the skin as an anesthetic cream, sprayed or gelled onto mucous membranes, or used as eye drops for the eyes.
Furthermore, lidocaine might be administered via intravenous injection following a heart attack (myocardial infarction) to quell ventricular tachycardia and diminish the chances of ventricular fibrillation – both of which are critical irregularities in heart rhythm posing life-threatening risks.
