From the Research

Concentration of 1% Lidocaine

• The concentration of 1% lidocaine is 10 milligrams (mg) per milliliter (ml) 2, 3, 4, 5, 6
• This means that for every 1 ml of 1% lidocaine solution, there are 10 mg of lidocaine
• The studies do not provide any information that contradicts this concentration, and it is a widely accepted value in the medical field

Calculation of Concentration

• To calculate the concentration of 1% lidocaine in mg/ml, we can use the following formula: (1 g/100 ml) x (1000 mg/1 g) = 10 mg/ml
• This calculation is based on the definition of a 1% solution, which is 1 gram of solute per 100 milliliters of solution
• The studies do not provide any alternative calculations or concentrations for 1% lidocaine 2, 3, 4, 5, 6
