The solid lines represent the linear regression fit to the data. The method was adequately accurate and precise and fulfilled the validation requirements for quantitative boutique En Ligne Clopidogrel of drugs and their metabolites in biological samples. Several reports in the literature have indicated that the ethnic background of subjects has an influence on the pharmacokinetics of the parent drug.
According to the published data, the Cmax values of clopidogrel varied from 0, Boutique En Ligne Clopidogrel. The Cmax of 2. A possible reason for the ethnicity-specific responses is significant variability in the frequencies of the CYP2C19 allelic variants found in different ethnic groups, which may affect the metabolism of clopidogrel [ 30 ].
Clopidogrel pharmacokinetics in patients with cardiovascular disease may differ from those in healthy subjects. A similar conclusion may be drawn from the results of the present study, where the Cmax values of the H3 and H4 isomers of CTM were 5.

We could speculate that conversion of clopidogrel into the H4 boutique En Ligne Clopidogrel isomer of the thiol metabolite was diminished in the studied group of patients, compared with healthy volunteers.
One possible reason for this is impaired blood flow to the body tissues associated with cardiovascular disorders. This may result in decreased drug absorption and impaired metabolism of the drug in the liver. These variables may also have an influence on systemic exposure to the CTM isomers.
The multivariate analysis of variance showed no association between the combination of these variables and the pharmacokinetic parameters of the CTM isomers. Identification of the sources that influence both the pharmacokinetic and pharmacodynamic responses may be difficult because it is unclear whether these factors fully explain the variability of the response to clopidogrel treatment.
In the present study, Boutique En Ligne Clopidogrel, variability in clopidogrel pharmacodynamics measured by ADP-induced platelet aggregation was observed, and it was associated with plasma boutiques En Ligne Clopidogrel of the CTM isomers.
The significant correlation between the Cmax of the active H4 isomer and platelet aggregation indicates the usefulness of both factors as predictors of the patient response to clopidogrel therapy. Some studies have demonstrated that monitoring of platelet function may be especially useful in patients with decreased clopidogrel metabolism. Pharmacokinetic analysis of clopidogrel and its metabolites, especially the active H4 isomer, may be a useful tool for identification of patients who are at risk of high on-treatment platelet reactivity.
Routine monitoring of platelet aggregation and H4 plasma concentrations during clopidogrel treatment may improve clinical outcomes in patients with cardiovascular diseases. The results might be useful for designing a limited-sampling strategy in which accurate information on the antiplatelet effect of clopidogrel can be obtained using plasma concentrations determined in a few blood samples at appropriate times.
Strategies using a limited number of samples have proven to be useful in therapeutic monitoring of immunosuppressants [ 37 ] or anti-infective agents [ 38 ], Boutique En Ligne Clopidogrel. A significant correlation between the pharmacokinetic parameters of clopidogrel and the AUCt of the H4 isomer allows for prediction of patient exposure to the active metabolite in situations when only analysis of the parent compound is available.
Conclusion To our knowledge, this is the first study of the pharmacokinetics of clopidogrel and its main metabolites, the active H4 and inactive H3 and CLPM, in patients with cardiovascular diseases.
Around current exhibitions
Our results confirmed that pharmacokinetic data in healthy volunteers are not sufficient for accurate prediction of the therapeutic effect of clopidogrel in clinical conditions. The Cmax of the boutique En Ligne Clopidogrel H4 isomer and platelet aggregation measured with the Multiplate analyser may serve as indicators of the patient response to clopidogrel therapy. The differences in the pharmacokinetic parameters of clopidogrel and its metabolites that were found in the studied group suggest that further studies of genetic and non-genetic sources of inter-individual variability should be performed.
