Lidocaine or lignocaine is a common local anesthetic and antiarrhythmic drug. The most commonly encountered lidocaine preparations are marketed by AstraZeneca under the brand names Xylocaine and Xylocard, though lidocaine is also found in many other proprietary preparations. Lidocaine signifies the most collective local anesthetic (LA) agent engaged in local or regional anesthesia, involved as a constituent of EMLA, a eutectic combination of lidocaine and prilocaine. Although most affected reactions are due to the collective metabolic produce of the ester local anesthetic, para-aminobenzoic acid, cross-reactivity between esters is mutual. Ingredients in LA solutions such as antioxidants or preservatives including metabisulphite or parabens may also elicit allergic or adversarial reactions. Articaine solutions should be evaded in those allergic or hypersensitive to sulfite, due to the content of sodium metabisulphite as the vasoconstrictor's antioxidant in it. The LA (without preservatives or adrenaline) may be skin tested. True allergy to LA is infrequent, with a genuine immunological response expressive only of all opposing reactions to these medicines In traditional classifications, adverse responses to LA have been considered as allergic, toxic and autonomic. Most of the patients experiencing dental procedures display some grade of autonomic response to an injection, such as sweating, tachycardia or even syncope. However, it is typically mild and transient. Toxic reactions are typically detected as a sign of a rapid intra-vascular injection of LA or may be related to an overdose in patients imperfectly metabolizing the drug.
