[Abstract]:research objective
To establish a quantitative analysis of ILP and its metabolites P88 and P95 by liquid chromatography tandem mass spectrometry (LC-MS/MS) in human plasma samples, which meet the clinical pharmacokinetic requirements of ILP (ILP), and determine the concentration of ILP and its metabolites P88, P95 drug concentration in the plasma samples of Chinese healthy volunteers, and draw the concentration of three kinds of drugs to be measured. The time curve was used to calculate its pharmacokinetic parameters, and to investigate its pharmacokinetic characteristics in vivo, so as to provide data support for the listing of ilpridone tablets.
Using acetonitrile as a eluant solid phase extraction method, the LC-MS/MS analysis of peridone and its metabolites P88, P95 in human plasma was carried out with the gradient elution of methanol -10mM acetate -0.1% formic acid solution as the mobile phase, and the separation of three kinds of samples and the internal standard SUPELCOAscentis-C18 (50mm x 4.6mm I.D., 5 micron m particle size) of the internal standard was separated. In MS, the electrospray ionization source (ESI) was selected and the mode of positive ion multiple reaction monitoring (MRM) was used. The ion pairs used for quantitative analysis were m/z427.3 to m/z261.0 (Pan Litong), m/z429.3 to m/z261.0 (metabolite P88), m/z429.3 to m/z261.0 (P95 of metabolites) and m/z256.3 to (internal standard phenhydramine). The relevant provisions of the food and Drug Administration (FDA) of the United States were confirmed in this study. The precision and accuracy of the method, specificity, linear range, minimum quantitative lower limit, extraction recovery, matrix effect and stability under various conditions were investigated.
The clinical trial scheme was formulated in accordance with the Helsinki declaration, the drug management law of People's Republic of China, and other relevant regulations. 16 healthy subjects were chosen to take oral 1mg, 3mg and two doses of peridone tablets. The plasma samples were collected at different time and LC-MS/MS method was used to determine the plasma samples and their metabolites P88, P95 The drug concentration time curve was plotted and the pharmacokinetic parameters were calculated by DAS3.0 (Drugand Statistics) software. The pharmacokinetics of peridone in human body was studied by SPSS analysis.
In the human plasma samples established in this study, the quantitative analysis of peridone and its metabolite P88, P95 LC-MS/MS method, no endogenous interference was found at the peak position of three kinds of subjects and internal standard diphenhydramine; the linear peri of irido Pan Litong and its metabolite P88, P95 were 5-1500pg/mL, and the lowest quantitative lower limit was 5pg/mL The accuracy of the QC samples of low, middle and high concentrations was not more than 15%. The recovery rates of the extraction of Pan Litong and its metabolites P88, P95, middle and high levels were 85.89 + 4.08%, 95.17 + 6.93%, 86.07 + 1.07%, 97.98 + 5.29%, 92.29 +, 92.29 +, 84.04 + 6.93%. The yield was high and stable, and the matrix effects of peridone and its metabolites P88, P95 were 81.96 + 5.10%, 85.55 + 9.09%, 95.86 + 1.97%, 88.20 + 2.68%, 91.18 + 10.05%, 97.51 + 1.75% and 91.27 + 5. The stability is good, the relative error is not more than 15%. The accuracy and precision of the plasma samples are not more than 15% after 10 times the dilution, and the dilution of the plasma samples does not affect the determination of the samples. The human plasma samples set up in this subject are simultaneously quantifying the LC-MS/MS method of the Irone and its metabolite P88, P95, and the spirit of the plasma sample. High sensitivity, good selectivity, short analysis time, good reproducibility and accuracy, which provide support for the clinical pharmacokinetics of irperidone.
16 Chinese healthy subjects were given 1mg and 3mg eperidone tablets. The concentration of plasma drugs was detected by the established LC-MS/MS method. The drug concentration time curves of eperidone and metabolic products P88 and P95 were plotted and the pharmacokinetic parameters were calculated. The main pharmacokinetic parameters of peridone and metabolic products P88 and P95 (AUC0-t, AUC0- infinity and Cmax) were used for linear correlation analysis. The results showed that the pharmacokinetic process of peridone in the human body was in line with the nonlinear kinetic process after a single dose of 1~3mg dose within a single dose of 1~3mg. The pharmacokinetic process of the metabolites P88 and P95 was not judged by the linear pharmacokinetics process.
