چکیده

Knowledge of pharmacokinetic-pharmacodynamic (PK/PD) properties of antihypertensive drugs may optimize drug therapy of hypertension. PK/PD modeling in clinical research could contribute in drug development and clinical practice in several aspects, including an evaluation of the efficacy and safety of antihypertensive agents, enhancement of information during the development process, identification of factors that contribute to drug response variability, by allowing a rapid identification of poor or non-responders and by helping to determine optimal antihypertensive drug and dose requirements in each hypertensive patient. There are some limitations in PK/PD modeling of antihypertensive drugs in the clinical setting, including application of inadequate pharmacodynamic models and the inability to study large doses of antihypertensive drugs in order to determine the complete pharmacodynamic range of their antihypertensive effect. The aim of the present review is to describe the current knowledge of PK/PD modeling of antihypertensive drugs in basic and clinical research and its future applications.

Drug interactions in hypertension.

Interactions between drugs and antihypertensive agents can result in either increased or decreased antihypertensive effects. These interactions may be pharmacokinetic or pharmacodynamic in type, resulting in either altered plasma drug concentrations or altered drug effects at similar plasma concentrations. Drugs may limit the absorption of antihypertensive agents, alter their metabolism through...

Antihypertensive pharmacogenetics: getting the right drug into the right patient.

Pharmacogenetic investigation seeks to identify genetic factors that contribute to interpatient and interdrug variation in responses to antihypertensive drug therapy. Classical studies have characterized single gene polymorphisms of drug metabolizing enzymes that are responsible for large interindividual differences in pharmacokinetic responses to several antihypertensive drugs. Progress is bei...

A Bayesian approach for dose-escalation in a Phase I clinical trial incorporating pharmacodynamic endpoints.

Bayesian decision procedures have already been proposed for and implemented in Phase I dose-escalation studies in healthy volunteers. The procedures have been based on pharmacokinetic responses reflecting the concentration of the drug in blood plasma and are conducted to learn about the dose-response relationship while avoiding excessive concentrations. However, in many dose-escalation studies,...

Pharmacodynamic and Pharmacokinetic Interactions of Propranolol with Garlic (Allium sativum) in Rats

Garlic preparations and propranolol (PRO) are agents recognized as cardioprotective and potent antihypertensive agents when they are used individually. However, there is no report available to explain the role of combined therapy during simultaneous hypertension and myocardial damage in rats. We aimed to determine the pharmacokinetic and pharmacodynamic interaction of PRO with garlic homogenate...

Population Pharmacokinetic and Pharmacodynamic Modeling

As we acquire experience with the clinical and pharmacokinetic behavior of a drug, it is very desirable to capture this experience and its related information in the form of a population pharmacokinetic model, and then to relate the behavior of the model to the clinical effects of the drug or to a linked pharmacodynamic model. The purpose of population modeling is thus to describe and capture o...
