Study Notes

Bioavailability Studies

  • Sampling time for blood and/or urine in single-dose bioavailability studies is usually at least several half-lives of the drug.

Comparison in Multiple-Dose Studies

  • Steady-state levels are determined by comparing the area under the curve (AUC) during the dosing interval at steady-state to the AUC after the first dose.

Measurements in Single-Dose Studies

  • Peak concentration (Cmax) and area under the curve (AUC) are measured in single-dose bioavailability studies.

Study Design and Population

  • Single-dose bioavailability studies are typically conducted in normal, healthy adults.
  • A crossover or parallel design is usually used for single-dose bioavailability studies.

Test your knowledge of single-dose and multiple-dose bioavailability studies with this quiz. Explore the design and conduct of these studies in normal adults, including fasting state requirements and comparison to reference materials.
