J Pharmacol Exp Ther 2024; 388:190-200. [PMID: 37863485 DOI: 10.1124/jpet.123.001767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 09/29/2023] [Accepted: 10/04/2023] [Indexed: 10/22/2023] Open
Abstract
This study aimed to evaluate the effects of cytochrome P450 3A4 (CYP3A4) gene polymorphism and drug interaction on the metabolism of blonanserin. Human recombinant CYP3A4 was prepared using the Bac-to-Bac baculovirus expression system. A microsomal enzyme reaction system was established, and drug-drug interactions were evaluated using Sprague-Dawley rats. Ultra-performance liquid chromatography-tandem mass spectrometry was used to detect the concentrations of blonanserin and its metabolite. Compared with wild type CYP34A, the relative clearance of blonanserin by CYP3A4.29 significantly increased to 251.3%, while it decreased notably with CYP3A4.4, 5, 7, 8, 9, 10, 12, 13, 14, 16, 17, 18, 23, 24, 28, 31, 33, and 34, ranging from 6.09% to 63.34%. Among 153 tested drugs, nimodipine, felodipine, and amlodipine were found to potently inhibit the metabolism of blonanserin. Moreover, the inhibitory potency of nimodipine, felodipine, and amlodipine varied with different CYP3A4 variants. The half-maximal inhibitory concentration and enzymatic kinetics assay demonstrated that the metabolism of blonanserin was noncompetitively inhibited by nimodipine in rat liver microsomes and was inhibited in a mixed manner by felodipine and amlodipine in both rat liver microsomes and human liver microsomes. When nimodipine and felodipine were coadministered with blonanserin, the area under the blood concentration-time curve (AUC)(0-t), AUC(0-∞), and C max of blonanserin increased. When amlodipine and blonanserin were combined, the C max of blonanserin C increased remarkably. The vast majority of CYP3A4 variants have a low ability to catalyze blonanserin. With combined administration of nimodipine, felodipine, and amlodipine, the elimination of blonanserin was inhibited. This study provides the basis for individualized clinical use of blonanserin. SIGNIFICANCE STATEMENT: The enzyme kinetics of novel CYP3A4 enzymes for metabolizing blonanserin were investigated. Clearance of blonanserin by CYP3A4.4, 5, 7-10, 12-14, 16-18, 23-24, 28, 31, 33, and 34 decreased notably, but increased with CYP3A4.29. Additionally, we established a drug interaction spectrum for blonanserin, in which nimodipine, felodipine, and amlodipine kinetics exhibited mixed inhibition. Moreover, their inhibitory potencies decreased with CYP3A4.4 and 5 compared to CYP3A4.1. This study provides essential data for personalized clinical use of blonanserin.

Abstract
Blonanserin is a novel oral antischizophrenic drug. Under fasting (n = 50) and fed (n = 60) conditions, this study compared the bioequivalence of the generic blonanserin tablet with the reference blonanserin tablet. In this single-center, randomized, open-label, 2-period, 2-sequence, crossover study, 110 patients were randomly given a 4-mg dose of either the test or reference blonanserin tablet with a 14-day washout period. Blood samples were taken before performing and up to 72 hours following. A validated high-performance liquid chromatography-tandem mass spectrometry technique was used to measure the levels of blonanserin in plasma. Safety was evaluated throughout the study. The study found no significant differences in the maximum observed drug concentration in the plasma (Cmax ), the area under the plasma concentration-time curve from time 0 to the last sampling time (AUC0-t ), and the area under the plasma concentration-time curve from time 0 to infinity (AUC0-∞ ) between the 2 blonanserin formulations. The 90% confidence intervals of the geometric mean ratio of the test/reference formulations for Cmax , AUC0-t , and AUC0-∞ were within the 80%-125% limit. Food dramatically raised blonanserin exposure, and also significantly prolonged the lag time of absorption. No serious adverse events occurred. These results indicate that the 2 blonanserin formulations were bioequivalent and well tolerated in healthy Chinese subjects. In clinical treatment, it is necessary to consider the food effect of blonanserin.

JOURNAL OF ANALYTICAL METHODS IN CHEMISTRY 2022; 2022:5914581. [PMID: 35433070 PMCID: PMC9010218 DOI: 10.1155/2022/5914581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 01/26/2022] [Accepted: 03/08/2022] [Indexed: 06/14/2023]
Abstract
A high-performance liquid chromatographic method coupled with triple quadrupole mass spectrometry (LC-MS/MS) for the analysis of blonanserin and its active metabolite, N-desethyl blonanserin, in rat plasma has been developed and validated. The biological samples were treated by simple direct protein precipitation before separation on an Agilent Eclipse Plus C18 column (4.6 × 100 mm, 3.5 μm) with a column temperature of 35°C at a flow rate of 0.5 mL/min. The mobile phase A is a mixture of methanol and water (75 : 25, v/v, 5 mM ammonium formate), and the mobile phase B is acetonitrile containing 0.1% formic acid. The ratio of mobile phase A to mobile phase B is 15 : 85. Electrospray ionization (ESI) multiple reaction monitoring modes are used for detection, which are m/z 368.10 ⟶ 296.90 (blonanserin), m/z 340.15 ⟶ 297.05(N-desethyl blonanserin), and m/z 348.15⟶ 302.05 (N-desethyl blonanserin-d8). The linear response range was 0.1-100.0 ng/mL for blonanserin and N-desethyl blonanserin. The lower limit of quantification (LLOQ), calibration curves, carryover, and matrix effects were sufficiently accurate and precise according to the National Medical Products Administration (NMPA) guidelines for bioanalytical method validation. This analytical method was successfully applied in a blonanserin-poloxamer thermosensitive gel pharmacokinetic study in rats.

Abstract
We developed and validated a novel, sensitive, selective, and inexpensive high-performance liquid chromatography (HPLC) method for the determination of tadalafil in rats plasma and to investigate the effect of grapefruit juice on the pharmacokinetics of tadalafil in rats. The ZORBAX Eclipse XDB-C18 (4.6 × 150 mm, 5 μm) chromatography column can be used to separate tadalafil and carbamazepine (internal standard, IS). A mixture of acetonitrile-0.2% trifluoroacetic acid-water (48 : 10 : 42, V/V/V) was used as the mobile phase with a flow rate of 1.0 mL/min. The column temperature was set at 35.0°C. The detection wavelength was set at 286 nm. The tadalafil was extracted by ethyl acetate from plasma at the alkaline condition. 12 healthy male Sprague-Dawley (SD) rats were randomly divided into two groups, Group A (experimental group, received grapefruit juice 5 mL/kg for 7 days) and Group B (control group, received normal saline for 7 days). All the rats were given a single dose of tadalafil (5 mg/kg) after the last administration. The main pharmacokinetic parameters were calculated by DAS 2.0 software. Under the conditions of this experiment, the plasma concentrations of tadalafil in the range of 10–2000 ng/ml had a good linear relationship. The intra- and interday precision for tadalafil in plasma were less than 15%, and the relative recovery rate was good at low, medium, and high QC levels. The Cmax of tadalafil in the control group and the experimental group was (725.89 ± 161.59) ng/mL and (1271.60 ± 179.31) ng/mL, t1/2 was (9.28 ± 2.07) h and (11.70 ± 1.47) h, AUC (0-t) was (7399.61 ± 696.85) ng·h/mL and (9586.52 ± 2048.81) ng·h/mL, and AUC(0-∞) was (7995.50 ± 707.23) ng·h/mL and (10639.43 ± 2235.94) ng·h/mL, respectively. Results show that the Cmax of tadalafil in group A was 75.17% higher than that in group B, the Vz/F was also reduced, and the t1/2 was increased by 2.42 h. The developed HPLC–DAD method for the determination of tadalafil in rats plasma was accurate, reproducible, specific, and it was found to be suitable for the pharmacokinetics of tadalafil and food-drug interactions. Grapefruit juice can inhibit the metabolism of tadalafil and increase the exposure of tadalafil in rats.

Abstract
PURPOSE/BACKGROUND Blonanserin is a novel antipsychotic drug approved for the treatment of schizophrenia in East Asia. The main objective of the present study was to investigate the effect of alcohol on the pharmacokinetic properties of blonanserin and its metabolite N-deethyl blonanserin in healthy Chinese male subjects under fasting conditions. METHODS/PROCEDURES The study was designed as a randomized, open-label, crossover clinical investigation in 10 male volunteers, each of whom received 2 treatments under fasted conditions: treatment A, blonanserin (8 mg) with water, and treatment B, blonanserin (8 mg) with alcohol (1 mL/kg). FINDINGS/RESULTS The average values of areas under the curve (AUCs) and mean peak plasma concentrations (Cmax) were noticeably increased by alcohol consumption. In treatment A, average values of AUC0-24h, AUC0-∞, and Cmax were 3178 ng/h/L, 3879 ng/h/L, and 492 ng/L for blonanserin, and 1932 ng/h/L, 4208 ng/h/L, and 137 ng/L for N-deethylated blonanserin, respectively. In treatment B, AUC0-∞ and Cmax were both increased 2.4-fold for blonanserin and 1.4-fold and 1.7-fold, respectively, for N-deethylated blonanserin (P < 0.05). Compared with treatment A, clearance (Clz/F) of blonanserin and N-deethylated blonanserin decreased significantly (2.4-fold and 1.7-fold, respectively) in treatment B (P < 0.05). Alcohol delayed the absorption and reduced the clearance of blonanserin, leading to a 1.8-fold increase in the time to reach Cmax (Tmax) and half life time (t1/2) (P < 0.05). IMPLICATIONS/CONCLUSIONS Alcohol increased the bioavailability of blonanserin and N-deethyl blonanserin in healthy subjects and the marked effect of alcohol on blonanserin bioavailability should be taken into consideration in deciding dosing schedules in clinical therapy.
