Bioavailability & Bioequivalence

Bioavailability is the measurement of rate and amount of API (Active Pharmaceutical Ingredient) that reaches the body and available in the targeted site of action

Types of Bioavailability

  • Absolute Bioavailability
  • Relative bioavailability

Bioequivalence is the comparison of bioavailability of two or more drug products containing the same formulations. Bioequivalence may be demonstrated by the in vivo or in vitro methods

Importance of Bioequivalence Studies

  • To assess the outright bioavailability of measurements structure contrasted and reference dose structures
  • Dose proportionality study to decide whether bioavailability parameters are straight over proposed measurement
  • Intra or inter subject variability
  • Intervention study to examine effect of drug
