Lidocaina Cloridrato S.A.L.F.

Lidocaine, the active ingredient in Lidocaina Cloridrato S.A.L.F., is a local anesthetic (amide) presented as a sterile solution for infiltration and intravenous use. It provides reversible nerve blockade for minor surgical, dental, and regional anesthesia procedures.

GNH USA supplies Lidocaina Cloridrato S.A.L.F. as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Lidocaine is a local anesthetic used to block nerve conduction in various clinical settings. - Minor surgical or dental procedures: provides local anesthesia to reduce pain during the procedure. - Infiltration anesthesia: produces numbness in targeted tissue for minor interventions. - Nerve block: achieves regional anesthesia for specific nerve territories. - Intravenous regional anesthesia (Bier block): enables temporary limb anesthesia for short surgeries. - Antiarrhythmic therapy (IV use): stabilizes cardiac rhythm in certain arrhythmias.

Lidocaine may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Tingling or numbness at the injection site - Metallic taste in the mouth - Dizziness or light‑headedness - Nausea or vomiting - Headache - Mild hypotension

Serious or Rare Side Effects: - Methemoglobinemia - Cardiac arrhythmias or conduction block - Seizures or central nervous system toxicity - Allergic reactions including anaphylaxis - Respiratory depression - Severe hypotension or cardiovascular collapse

Before using lidocaine, consider the following safety measures. - Allergy assessment: verify no known hypersensitivity to amide‑type local anesthetics. - Cardiac monitoring: observe patients with pre‑existing heart disease or conduction abnormalities. - Dose limitation: avoid exceeding recommended maximum doses, especially with repeated infiltrations. - Concurrent medications: review use of other sodium channel blockers or CYP inhibitors. - Pediatric and geriatric use: adjust dosing and monitor closely in vulnerable populations. - Store below 25°C: keep in the original container, protect from light and moisture.

Lidocaine can interact with several drugs, requiring caution.

Major Interactions (Avoid): - Class I antiarrhythmics (e.g., quinidine): may increase plasma lidocaine levels. - Strong CYP3A4 inhibitors (e.g., ketoconazole): can raise concentrations and toxicity risk. - Beta‑adrenergic blockers (e.g., propranolol): may enhance cardiotoxic effects. - Concurrent use of other local anesthetics: additive toxicity. - Methylene blue: may precipitate methemoglobinemia.

Moderate Interactions (Monitor Closely): - CYP1A2 inducers (e.g., carbamazepine): may reduce lidocaine efficacy. - Diuretics (e.g., furosemide): can alter plasma protein binding. - General anesthetics (e.g., propofol): may potentiate central nervous system depression. - Anticonvulsants (e.g., phenytoin): may affect seizure threshold. - Alcohol consumption: can increase CNS depressive effects.
