Cavg is the average concentration of a drug in the central circulation during a dosing interval in steady state. It is calculated by

C avg = A U C τ , ss τ {\displaystyle C_{\text{avg}}={\frac {AUC_{\tau ,{\text{ss}}}}{\tau }}}

where A U C τ , ss {\displaystyle AUC_{\tau ,{\text{ss}}}} is the area under the curve and τ {\displaystyle \tau } the dosing interval.
