Lidocaine (C14H22N2O) is an exogenous organic compound with an average molecular weight of 234.34 g/mol that exists as a solid at room temperature. Lidocaine belongs to the xylenes, a subclass of benzene and substituted derivatives within the organic compounds. It is utilized as an anti-arrhythmia drug and a local anaesthetic (PMC10507411 ). It is used in the treatment of pain (PMC11340200 , PMC6558355 ) and has a therapeutic effect on pain (PMC11340200 ). However, it is associated with bradycardia (PMC1950874 ), hypotension (PMC1950874 ), and necrosis (PMC5078905 ).
The compound targets several proteins, including the epidermal growth factor receptor (EGFR), sodium channel protein type 10 subunit alpha (SCN10A), sodium channel protein type 5 subunit alpha (SCN5A), alpha-1-acid glycoprotein 1 (ORM1), multidrug and toxin extrusion protein 1 (SLC47A1), potassium voltage-gated channel subfamily A member 5 (KCNA5), and is a blocker of potassium channel subfamily K member 2 (KCNK2). Regarding sodium channel protein type 9 subunit alpha (SCN9A), lidocaine stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses thereby effecting local anesthetic action.
Lidocaine is found in 25 recorded sources, including drinking water, indoor air, food preservation, and various healthcare, pharmaceutical, and veterinary products such as anesthetics, antipruritics, and antiarrhythmics (class i and iii). It is also found in household cleaning and consumer products, including soap detergents and tobacco smoke filters, as well as electrical and electronic equipment. Exposure routes include oral, intravenous, intramuscular, subcutaneous, topical, inhalation, and various intra-site administrations.
Lidocaine stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses thereby effecting local anesthetic action. Lidocaine alters signal conduction in neurons by blocking the fast voltage gated sodium (Na+) channels in the neuronal cell membrane that are responsible for signal propagation. With sufficient blockage the membrane of the postsynaptic neuron will not depolarize and will thus fail to transmit an action potential. This creates the anaesthetic effect by not merely preventing pain signals from propagating to the brain but by aborting their birth in the first place.

Symptoms
Symptoms of overdose include convulsions, hypoxia, acidosis, bradycardia, arrhythmias and cardiac arrest.
Treatment
The first step in the management of systemic toxic reactions consists of immediate attention to the establishment and maintenance of a patent airway and assisted or controlled ventilation with oxygen and a delivery system capable of permitting immediate positive airway pressure by mask. If convulsions occur, the objective of the treatment is to maintain ventilation and oxygenation and support the circulation. Oxygen must be given and ventilation assisted if necessary (mask and bag or tracheal intubation). Should convulsions not stop spontaneously after 15-20 seconds, an anticonvulsant should be given i.v. to facilitate adequate ventilation and oxygenation. Thiopental sodium 1-3 mg/kg i.v. is the first choice. Alternatively diazepam 0.1 mg/kg bw i.v. may be used, although its action will be slow. Prolonged convulsions may jeopardise the patient's ventilation and oxygenation. If so, injection of a muscle relaxant (e.g. succinylcholine 1 mg/kg bw) will facilitate ventilation, and oxygenation can be controlled. Early endotracheal intubation must be considered in such situations. If cardiovascular depression is evident (hypotension, bradycardia), ephedrine 5-10 mg i.v. should be given and may be repeated, if necessary, after 2-3 minutes. Should circulatory arrest occur, immediate cardiopulmonary resuscitation should be instituted. Continual oxygenation and ventilation and circulatory support as well as treatment of acidosis are of vital importance. (4)
Allergic diseases, also known as allergies, are a number of conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, a runny nose, shortness of breath, or swelling. Common allergens include pollen and certain foods. Metals and other substances may also cause allergies. Food, insect stings, and medications are common causes of severe allergic reactions. Allergies can be due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE) binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. Allergies are among the most common conditions in the world. In the developed world, about 20% of people are affected by allergic rhinitis, about 6% of people have at least one food allergy, and about 20% have atopic dermatitis at some point in time.
