ABSTRACT
Aim To investigate the combined pharmacokinetic-pharmacodynamic(PK-PD) model of irbesartan in healthy Chinese male volunteers. Methods Eighteen healthy male volunteers received 300 mg irbesartan tablet orally. The plasma drug concentration (C_p) was determined by HPLC and pharmacologic effects, including SBP, DBP and HR, were measured simultaneously. The pharmakinetic and PK-PD model parameters were calculated. Results The pharmacokinetic profiles were best fitted a two-compartment open model. There was a hysteresis loop between effects and plasma concentrations. The relationship between effects and effect compartment concentrations of drugs could be represented by the Sigmoid-E_ max model. Conclusion We successfully eatablished the PK-PD model of irbesartan in healthy male volunteers. These findings may provide a more rational basis for patient-specific dosage individualization.
