An investigаtiоnаl оrаl antibiоtic demonstrates nonlinear pharmacokinetic behavior at doses exceeding 200 mg in some patients. Pharmacokinetic parameters obtained after single-dose IV bolus and oral administration are summarized in the table below. Based on these data, determine which mechanism(s) from the list provided could explain the observed dose-dependent kinetics. The drug's hepatic extraction ratio (ER) is 0.37. Support your answer with relevant calculations and pharmacokinetic reasoning. Selection of incorrect mechanisms or unsupported conclusions will result in point deductions. (9 pts. total) Saturated gastrointestinal efflux transport; Saturated gastrointestinal influx transport; Saturated hepatic metabolism; Inhibition of drug metabolizing enzyme in the liver; Induction of drug metabolizing enzyme in the liver; Saturated renal active tubular secretion; Saturated plasma protein binding; Saturated active efflux transport in the tissue; Saturated active influx transport in the tissue; Saturated tissue binding. Single IV dose (mg) 200 500 1000 AUC (mg*h/L) 34.2 103 238 t1/2 (h) 4.4 6.3 8.7 Single PO dose (mg) 200 500 1000 AUC (mg*h/L) 18.1 60.4 157 t1/2 (h) 4.4 6.3 8.7
