Abstract:
Objective - to develop a method for the quantitative determination of the drug phenazepam in mixed saliva. For the study, samples were obtained mixed saliva in 6 patients in inpatient treatment in a psychiatric hospital. In order to correct the development of the underlying disease, patients took the drug - phenazepam. For comparison, samples of mixed saliva of healthy volunteers (n=6) who did not take medications were studied. A technique has been developed for the quantitative determination of the drug phenazepam in mixed saliva on a Sciex 4500 triple quadrupole liquid chromatography-mass spectrometer with ionization, separation and detection of samples. Allows you to determine the concentration of phenazepam in mixed saliva with an accuracy of from 102 to 109% and can be used to control the removal and dosing of drugs.

Protein-Drug Binding: Determination Methods
Indirect methods involve isolating the bound drug from its free form in biological samples such as blood, serum, or plasma. These techniques aim to measure the percentage of drugs bound to proteins. Equilibrium dialysis is a commonly used method where the free drug concentration at equilibrium is measured by separating the bound...
