Formula Explained

The basic formula for dosage calculation is:

Dosage = (Desired Dose × Patient Weight) ÷ Medication Concentration

This formula accounts for:

  • Patient weight - Important for medications dosed by weight (e.g., children)
  • Medication concentration - The strength of the medication
  • Desired dose - The amount of medication needed

Additional factors may be considered based on the administration route and specific medication requirements.

Worked Example

Let's calculate the dosage for a 70 kg patient who needs 5 mg/kg of a medication with a concentration of 100 mg/5 mL:

Dosage = (5 mg/kg × 70 kg) ÷ 100 mg/mL

Dosage = 350 mg ÷ 100 mg/mL

Dosage = 3.5 mL

Therefore, the patient should receive 3.5 mL of the medication.
