| Outline of Final Research Achievements |
Measuring blood concentration of anti- HIV drugs is important for the optimization of the treatment and the prevention of the acquisition of drug-resistance. The drug concentration in hair is thought to reflect average blood concentration of the drug, and it is expected that we can estimate the long-term change of the blood levels of the drug by measuring drug concentrations of hairs from hair roots to hair tips.
This time we established the beads spall method for the drug extraction from the hair, and we measured the hair and blood concentrations of tenofovir (TFV) and emtricitabine (FTC), which are reverse transcriptase inhibitors, in HIV infected patients by using a liquid chromatography mass spectrometry. As a result, the possibilities to be able to estimate the long-term change of the blood levels of TFV and FTC by measuring the drug concentration of the hair were shown.
