Abstract

INTRODUCTION:

β-blocker therapy plays an important role in the treatment of various diseases, including hypertension, myocardial infarction and heart failure. Although all β-blockers shared their ability to competitively block β1-adrenoceptor, this therapeutic class showed great heterogeneity in their pharmacokinetic (PK) and pharmacodynamic (PD) properties.

AREAS COVERED:

The present review describes the models used for PK and PK/PD evaluation of β-blockers and their applicability in preclinical and clinical studies. PK behavior of different β-blockers has been studied by means of individual compartmental and population PKs, allowing the estimation of relevant PK parameters and factors involved in intersubject variability. Different PK/PD models have been developed for the in vivo estimation of PD parameters of different cardiovascular effects of β-blockers.

EXPERT OPINION:

PK models and PK/PD modeling have clearly contributed to characterization of the PK and PD properties of β-blockers. Differences in cardiovascular actions between classical β-blockers and vasodilatory β-blockers need to be further studied in order to confirm the clinical benefits of the new-generation of β-blockers. PK/PD modeling may contribute to clarify the importance of heterogeneity of PK and PD properties of β-blockers potentially improving the selection of the adequate agent and dose regimen in the treatment of cardiovascular diseases.
