The 'Therapeutic Window' is the range of drug concentrations between:

  1. Zero and the peak plasma concentration reached after the first dose
  2. The minimum effective concentration and the minimum toxic concentration
  3. The end of the absorption phase and the beginning of the elimination phase
  4. The size of the loading dose and the size of the maintenance dose
Show answer and explanation

Correct answer: The minimum effective concentration and the minimum toxic concentration

The therapeutic window defines the plasma concentration range where the drug is effective without being toxic. Drugs with a narrow therapeutic window require careful monitoring of plasma levels.
