Drug A exhibits an oral bioavailability (F) of 42%. After a 10‑mg oral dose, 2.8 mg of unchanged drug is recovered in the feces. Biliary excretion is assumed negligible and the liver is the only site of metabolism. What should be its extraction ratio (ER) value?

In a bioavailability study, a healthy volunteer received 100 mg of Drug A intravenously, resulting in AUC0–24h and AUC0–∞ values of 1.34 and 1.76 mg·h/L, respectively. After the same subject received a 250‑mg oral dose of Drug A, the corresponding AUC0–24h and AUC0–∞ values were 1.71 and 2.34 mg·h/L. The oral bioavailability (F) of Drug A in this subject is calculated to be:
