Bioequivalence
The demonstration that two peptide products produce equivalent blood levels (Cmax and AUC within 80–125%) when administered at the same dose. Required for generic drug approval.
Frequently Asked Questions
What is Bioequivalence?
The demonstration that two peptide products produce equivalent blood levels (Cmax and AUC within 80–125%) when administered at the same dose. Required for generic drug approval.
Why is Bioequivalence important in peptide research?
Bioequivalence is a key pharmacological concept that determines how peptides interact with the body. Understanding this term helps practitioners optimize dosing protocols, predict therapeutic outcomes, and minimize side effects.

Cmax
The maximum (peak) concentration of a peptide in the blood after administration. Cmax is influenced by dose, administration route, and absorption rate.
AUC (area under curve)The total drug exposure over time, calculated as the integral of the concentration-time curve. AUC reflects both the amount absorbed and the rate of elimination. Used to assess bioequivalence.
BioavailabilityThe fraction of an administered dose that reaches systemic circulation unchanged. Subcutaneous injection provides 65–95% bioavailability for most peptides; oral bioavailability is typically below 1% without absorption enhancers.
