Amikacin Dilution for Intravenous Administration

For intravenous infusion, dilute 1 gram of amikacin in 100-200 mL of normal saline (0.9% sodium chloride). This is the standard preparation recommended by the FDA-approved prescribing information 1.

Preparation Details

The FDA drug label specifies that a 500 mg vial should be added to 100 or 200 mL of sterile diluent, which proportionally means a 1 gram dose requires the same volume range 1. This creates a concentration of 5-10 mg/mL, which falls within the stable concentration range of 0.25-5 mg/mL that maintains stability for 24 hours at room temperature 1.

Administration Parameters

  • Infusion time for adults: 30-60 minutes
  • Infusion time for pediatric patients: 30-60 minutes (adjust fluid volume based on ordered dose)
  • Infusion time for infants: 1-2 hours 1

Compatible Diluents

While normal saline is the standard choice, amikacin is also stable in 1:

  • 5% Dextrose Injection
  • 5% Dextrose and 0.2% Sodium Chloride
  • 5% Dextrose and 0.45% Sodium Chloride
  • Lactated Ringer's Injection

Critical Safety Points

Never physically premix amikacin with other drugs - it must be administered separately according to the recommended dose and route 1. This is essential to prevent incompatibilities and ensure proper dosing.

The prepared solution maintains stability for 24 hours at room temperature when diluted to concentrations between 0.25-5 mg/mL 1.
