A semi-compartmental model describing the pharmacokinetic-pharmacodynamic relationship [PDF]
Anesthesia and Pain Medicine, 2020 Frequently, we encounter the phenomenon of hysteresis in kinetic-dynamic modeling. The hysteresis loop in the concentration-effect curve suggests a time discrepancy caused by various pharmacokinetic and pharmacodynamic factors. To collapse the hysteresis
