Brief Summary:
The purpose of this study is to characterise the pharmacokinetic profiles of non-nucleoside analog reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs), and the influence of the individual characteristics on the pharmacokinetic parameters in the Spanish population of HIV-infected subjects.
Detailed Description:
The antiretrovirals were administered conventionally according to fixed dosage systems, or depending on the weight of the individual in the case of certain agents. However, the plasma levels of antiretrovirals following the administration of a fixed dose present a marked interindividual variability. Moreover, a significant proportion of the patients on treatment with PIs presented plasma levels regarded as suboptimal in previous studies.
Moreover, for the correct modification of the dosage of a drug, populational data on its pharmacokinetic behaviour during the dosing interval is required. Only by integrating this information with the specific characteristics of each individual is it possible, using mathematical models, to estimate the effect that a modification of the dosage of the drug would have on its plasma concentration. However, populational data on the pharmacokinetic behaviour of antiretroviral agents are still very limited at this moment, and have not always been obtained in populations similar to the one to which they are to be applied.
Thus, knowing the pharmacokinetic behaviour of the antiretroviral agents in our population and the influence of certain individual characteristics on this behaviour may be of great interest, since only in this way will we be able to tailor the dosage of antiretrovirals reliably in our patients.
