A cross-sectional study on metoprolol concentrations in various biological samples and their inter-correlations. BMC Pharmacol Toxicol 2024; 25:45. [PMID: 39118152 PMCID: PMC11311911 DOI: 10.1186/s40360-024-00773-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 07/26/2024] [Indexed: 08/10/2024] Open
Abstract
BACKGROUND Concentrations of metoprolol in exhaled breath condensate (EBC) have not been investigated. Herein, we aim to determine the metoprolol levels in EBC, plasma, and urine samples. METHODS Biological samples were collected from 39 patients receiving metoprolol. Metoprolol was determined using liquid chromatography mass spectrometery. The obtained metoprolol levels in biological fluids were investigated for possible inter-correlations. RESULTS Acceptable linearity was obtained with coefficient of determinations equal to 0.9998, 0.9941, and 0.9963 for EBC, plasma, and urine samples, respectively. The calibration curves were linear in the ranges of 0.6-500, 0.4-500, and 0.7-10,000 µg·L- 1 regarding EBC, plasma, and urine samples, respectively. The detection and quantification limits were (0.18, 0.12, and 0.21 µg·L- 1) and (0.60, 0.40, and 0.70 µg·L- 1) for EBC, plasma, and urine samples, respectively. The relative standard deviations for the intra- and inter-day replications were obtained between 5.2 and 6.1 and 3.3-4.6%, respectively. The obtained mean metoprolol levels in EBC, plasma, and urine samples of 39 patients were 5.35, 70.76, and 1943.1 µg·L- 1. There were correlations between daily dose and plasma and urinary concentrations of metoprolol in the investigated samples, whereas no significant correlation was observed for daily dose and EBC levels. The correlation among plasma-urine levels was significant, however, the non-significant correlation was obtained between plasma and EBC concentrations. CONCLUSION Metoprolol levels varied widely due to the metabolic pattern of the Azeri population, different dosages received by the patients, formulation effects, age, sex, and interactions with the co-administered drugs. A poor correlation of EBC-plasma concentrations and a significant correlation of plasma-urine concentrations were observed. Further investigations are required to provide the updated services to personalized medicine departments.

Garzinsky AM, Thomas A, Thevis M. Probing for factors influencing exhaled breath drug testing in sports- Pilot studies focusing on the tested individual's tobacco smoking habit and sex. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2022; 36:e9262. [PMID: 35094434 DOI: 10.1002/rcm.9262] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 01/25/2022] [Accepted: 01/26/2022] [Indexed: 06/14/2023]
Abstract
RATIONALE Exhaled breath (EB) was found to be a promising matrix in the field of sports drug testing due to the non-invasive and non-intrusive sampling procedure, but significant inter-individual variations regarding detected drug concentrations have been observed in previous studies. To investigate whether the detectability of doping agents in EB is affected by sex or tobacco smoking, two administration studies were conducted with male and female smokers and nonsmokers concerning the elimination of the beta blocker propranolol and the stimulant pseudoephedrine into EB. METHODS Following the administration of 40 mg propranolol or 30 mg pseudoephedrine, a total of 19 participants, including female and male nonsmokers as well as female and male smokers, collected EB and dried blood spot (DBS) samples over a period of 24 h. Respective analyte concentrations were determined using liquid chromatography and high-resolution tandem mass spectrometry, and semi-quantitative assays were characterized with regard to selectivity, limit of detection and identification, precision, linearity, and carryover. RESULTS Both propranolol and pseudoephedrine were identified in post-administration EB samples from female and male nonsmokers as well as female and male smokers, and the maximum detected drug levels ranged from 9 to 2847 pg/cartridge for propranolol and from 26 to 4805 pg/cartridge for pseudoephedrine. The corresponding DBS levels were in a range of 4-30 ng/mL for propranolol and 55-186 ng/mL for pseudoephedrine. CONCLUSIONS Neither the consumption of cigarettes nor the sex appears to represent a decisive criterion as to the detectability of propranolol or pseudoephedrine in EB, but inter-individual variations regarding the detected drug levels were observed among all studied population groups.

Plasma Concentrations of Methylphenidate Enantiomers in Adults with ADHD and Substance Use Disorder, with focus on high doses and relationship to Carboxylesterase activity. Basic Clin Pharmacol Toxicol 2022; 130:492-500. [PMID: 35040257 PMCID: PMC9303366 DOI: 10.1111/bcpt.13707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 01/11/2022] [Accepted: 01/12/2022] [Indexed: 11/29/2022]
Abstract
Scarce data are available on methylphenidate (MPH) plasma concentrations reached after doses higher than 180 mg. The interindividual and intraindividual variability in the exposure of MPH and ritalinic acid (RA) enantiomers was examined in 28 patients with ADHD and substance use disorders, with MPH daily doses between 30 and 600 mg (median 160 mg). MPH and RA plasma concentrations were analysed with an enantioselective LC–MS/MS method. d‐MPH plasma concentration/dose varied 25‐fold between subjects but was reasonably stable within an individual. Twelve subjects had quantifiable l‐MPH plasma concentrations, which accounted for up to 48% of the total MPH plasma concentration. The less active l‐MPH enantiomer could, in individuals with low carboxylesterase 1 (CES1) activity, contribute significantly to the total MPH plasma drug concentration and hamper the estimation of the exposure to the more active d‐MPH enantiomer. However, the high correlation between the total (d + l) RA/MPH metabolic ratio and the d‐RA/d‐MPH metabolic ratio (rs = 0.94) indicates that the ratio based on non‐enantioselective analysis could be used as a marker of CES1 activity. Whether this holds true for subjects with aberrant metabolism due to genetic variants or during concomitant treatment with inhibitors or inducers of the enzyme remains to be studied.

Evaluation of the effect of Shengxian Decoction on doxorubicin-induced chronic heart failure model rats and a multicomponent comparative pharmacokinetic study after oral administration in normal and model rats. Biomed Pharmacother 2021; 144:112354. [PMID: 34794233 DOI: 10.1016/j.biopha.2021.112354] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 10/13/2021] [Accepted: 10/19/2021] [Indexed: 12/28/2022] Open
Abstract
Shengxian Decotion (SXT), a well-known Traditional Chinese Medicine (TCM) formula composed of Astragali Radix, Bupleuri Radix, Cimicifugae Rhizoma, Anemarrhenae Rhizoma and Platycodonis Radix, is clinically considered as an effective formula against cardiovascular diseases. However, the exact effective substance of SXT in treating chronic heart failure (CHF) still remains unclear. In the current study, we investigated the benefit of SXT in doxorubicin (DOX)-induced CHF rats and established a UHPLC-MS/MS method to simultaneously determine 18 key compounds in a subsequent comparative pharmacokinetic study in normal and CHF rats. Histopathological studies, transmission electron microscopy, and echocardiography were applied to assess the therapeutic effect of SXT on DOX-induced CHF rats, which indicated that SXT significantly ameliorated DOX-induced CHF, similar to enalapril. In addition, we successfully established a UHPLC-MS/MS method to determine the pharmacokinetics of the components in rat plasma, which was validated with good linearity, inter-day and intra-day precisions and accuracies, matrix effects, extraction recovery, and stability values. Our results showed that only astragaloside IV showed increased plasma exposure in the CHF rats, while saikosaponin A, quercetin, timosaponin B-II, ferulic acid, isoferulic acid and formononetin decreased compared to their pharmacokinetic characteristics in the normal and CHF rats. This study demonstrates that SXT enjoys obvious therapeutic effect on DOX-induced CHF rats, and the altered metabolism of some compounds in SXT is affected by the pathological state of CHF rats. Our findings provide a better understanding of the in vivo exposure to complex compounds of SXT, supporting effective substance screening and further investigation of the therapeutic mechanism.

Garzinsky AM, Thomas A, Krug O, Thevis M. Probing for the presence of doping agents in exhaled breath using chromatographic/mass spectrometric approaches. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2021; 35:e8939. [PMID: 32881194 DOI: 10.1002/rcm.8939] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 08/28/2020] [Indexed: 06/11/2023]
Abstract
RATIONALE Exhaled breath (EB) has been demonstrated to be a promising alternative matrix in sports drug testing due to its non-invasive and non-intrusive nature compared with urine and blood collection protocols. In this study, a pilot-test system was employed to create drug-containing aerosols simulating EB in support of the analytical characterization of EB sampling procedures, and the used analytical method was extended to include a broad spectrum of prohibited substances. METHODS Artificial and authentic EB samples were collected using sampling devices containing an electret filter, and doping agents were detected by means of liquid chromatography and tandem mass spectrometry with unispray ionization. The analytical approach was characterized with regard to specificity, limits of detection, carry-over, recovery and matrix effects, and the potential applicability to routine doping controls was shown using authentic EB samples collected after single oral dose applications of glucocorticoids and stimulants. RESULTS The analytical method was found to be specific for a total of 49 model substances relevant in sports drug testing, with detection limits ranging from 1 to 500 pg per cartridge. Both ion suppression (-62%) and ion enhancement (+301%) effects were observed, and all model compounds applied to EB sampling devices were still detected after 28 days of storage at room temperature. Authentic EB samples collected after the oral administration of 10 mg of prednisolone resulted in prednisolone findings in specimens obtained from 3 out of 6 participants up to 2 h. In octodrine, dimethylamylamine (DMAA) and isopropylnorsynephrine post-administration EB samples, the drugs were detected over a period of 50, 48, and 8 h, respectively. CONCLUSIONS With the analytical approach developed within this study, the identification of a broad spectrum of prohibited doping agents in EB samples was accomplished. Application studies and stability tests provided information to characterize EB as a potential matrix in sports drug testing.
