🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking voltage-gated sodium channels on the inner side of nerve cell membranes. When these channels are blocked, sodium ions cannot enter the nerve cell, which prevents the nerve from generating and conducting an electrical impulse. This reversible blockade stops pain signals from travelling along the nerve to the brain, resulting in loss of sensation in the area supplied by that nerve. At higher concentrations, it can also affect the heart and central nervous system.
Mechanism Steps
💡 How to Take lidocyn plus injection
Strength: This medicine is available as an injection in various strengths, commonly 1% (10 mg/mL) and 2% (20 mg/mL) solutions. The specific strength depends on the product.
Dosage Information
| Adult Dosage | The dose of this medicine depends on the procedure, the area to be numbed, and the patient's weight and health status. For local infiltration, a common adult dose is 1 to 5 mL of 1% or 2% solution, but the maximum safe dose is usually 4.5 mg/kg without adrenaline and 7 mg/kg with adrenaline. For nerve blocks, doses vary widely. For ventricular arrhythmias, an initial intravenous dose of 1 to 1.5 mg/kg may be given, followed by a maintenance infusion. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. Doses are weight-based and must be calculated by a qualified clinician. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of this medicine. Doses should be reduced, and the lowest effective dose should be used. Monitoring for toxicity is recommended. |
| Renal Impairment | No specific dose adjustment is usually required for mild to moderate kidney disease. In severe kidney disease, metabolites may accumulate, and caution is advised. Consult a clinician for individualized dosing. |
| Hepatic Impairment | In patients with liver disease, the half-life of this medicine is prolonged. Dose reduction is recommended, and the lowest effective dose should be used. Monitor for signs of toxicity. |
| Maximum Daily Dose | The maximum safe dose is generally 4.5 mg/kg without adrenaline and 7 mg/kg with adrenaline. For intravenous use, the maximum total dose is usually 300 mg over 1 hour. Doses must be individualized by a clinician. |
