© 2020 Elsevier B.V. Alprazolam is used in the treatment of patients with anxiety disorders comorbid with alcohol use disorder. Some proportion of these patients does not respond adequately to treatment with alprazolam, while many of them experience dose-dependent adverse drug reactions. Results of the previous studies have shown that CYP3A is involved in the biotransformation of alprazolam, the activity of which is dependent, inter alia, on the polymorphism of the encoding gene. Objective: The objective of our study was to investigate the effect of 99366316G>A polymorphism of the CYP3A4 gene on the concentration/dose indicator of alprazolam in patients with anxiety disorders comorbid with alcohol use disorder, using findings on enzymatic activity of CYP3A (as evaluated by the 6-beta-hydroxy-cortisol/cortisol ratio measurement) and on CYP3A4 expression level obtained by measuring the miR-27b plasma concentration levels in patients with anxiety disorders comorbid with alcoholism. Material and methods: Our study enrolled 105 patients with anxiety disorders comorbid with alcohol use disorder (age - 37.8±14.6 years). Therapy included alprazolam in an average daily dose of 5.6±2.4 mg per day. Treatment efficacy was evaluated using the psychometric scales. Therapy safety was assessed using the UKU Side-Effect Rating Scale. For genotyping and estimation of the microRNA (miRNA) plasma levels, we performed the real-time polymerase chain reaction. The activity of CYP3A was evaluated using the HPLC-MS/MS method by the content of the endogenous substrate of the given isoenzyme and its metabolite in urine (6- beta-hydroxy-cortisol/cortisol). Therapeutic drug monitoring (TDM) has been performed using HPLC-MS/MS. Results: Our study revealed the statistically significant results in terms of the treatment efficacy evaluation (HAMA scores at the end of the treatment course): (GG) 3.0 [2.0; 5.0] and (GA) 4.0 [4.0; 5.0], p = 0.007; at the same time, the statistical significance in the safety profile was not obtained (the UKU scores): (GG) 3.0 [2.0; 3.8] and (GA) 3.0 [1.5; 4.0], p = 0.650. We revealed a statistical significance for concentration/dose indicator of alprazolam in patients with different genotypes: (GG) 1.583 [0.941; 2.301] and (GA) 2.888 [2.305; 4.394], p = 0.001). Analysis of the results of the pharmacotranscriptomic part of the study didn't show the statistically significant difference in the miR-27b plasma levels in patients with different genotypes: (GG) 25.6 [20.4; 28.8], (GA) 25.7 [19.7; 33.1], p = 0.423. At the same time, correlation analysis revealed a statistically significant relationship between the alprazolam efficacy profile evaluated by changes in HAMA scale scores and the miR-27b plasma concentration: rs = 0.20, p = 0.042. Also, we didn't reveal the correlation between the miRNA concentration and safety profile: rs = 0.15, p = 0.127. In addition, we revealed the relationship between the CYP3A enzymatic activity (as evaluated by 6-beta-hydroxycortisol/ cortisol ratio measurement) and the miR-27b plasma concentration: rs = −0.27, p = 0.006. At the same time, correlation analysis revealed a statistically significant relationship between the alprazolam concentration and the miR-27b plasma concentration: rs = 0.28, p = 0.003. Conclusion: The effect of genetic polymorphism of the CYP3A4 gene on the efficacy and safety profiles of alprazolam was demonstrated in a group of 105 patients with anxiety disorders comorbid with alcohol use disorder. At the same time, miR-27b remains a promising biomarker for assessing the level of CYP3A4 expression, because it correlates with the encoded isoenzyme's activity.

© 2019, Springer Nature B.V. The objective of this study was to determine the impact of polymorphism of CYP3A subfamily isoenzymes (allelic variants of CYP3A4*22 and CYP3A5*3) on the efficacy clopidogrel in patients with an acute coronary syndrome (ACS), who have undergone percutaneous coronary intervention (PCI). Platelet activity was determined on a VerifyNow P2Y12 test system in 81 patients with ACS aged 37–91 who had PCI. The activity of CYP3A4/5 was expressed as the ratio of the concentrations of cortisol and 6β-hydroxycortisol was performed by using high performance liquid chromatography. Genotyping was performed by using real-time polymerase real-time chain reaction. The frequencies for the CYP3A5 gene, rs 776746, were identified as follows: 77 (95.1%)—CC, 4 (4.9%)—CT; the allele frequencies by loci for the CYP3A4, rs rs35599367, were as follows: 78 (96.3%)—GG, 3 (3.7%)—AG. There was no statistically significant genotype-dependent difference between the presence of a minor T and G alleles and the presence of clopidogrel resistance (OR 3.53; 95% CI 0.46–26.94; p = 0.233 and p = 0.443, respectively). The average level of the metabolic relationship (6β-hydroxycortisol/cortisol) between the clopidogrel-resistant group and the normal platelet reactivity group was not statistically significantly different: 3.3 ± 2.8 versus 3.2 ± 3.2; p = 0.947. So, the activity of CYP3A4/5 was not related to platelet aggregation rates in this model. Genotyping and phenotyping CYP3A4\CYP3A5 does not predict the antiplatelet effect of clopidogrel. More extensive research is required to establish their clinical relevance.

© 2018 by the authors; licensee Modestum Ltd., UK. Objective: The problem of drug interactions is increasingly important today because they may induce serious adverse events as well as interfere with efficacy of pharmacotherapy. Combinations of drugs are most often prescribed to patients presenting with comorbid pathology. The incidence of a combination of arterial hypertension (AH) and acid-dependent diseases (ADDs) varies widely ranging from 11.6 to 50%. One of combinations of drugs prescribed to such patients is a combination of calcium channel blocker amlodipine and proton pump inhibitor omeprazole. The latter in the human body undergoes biotransformation mediated at the level of cytochrome P450 by isoenzymes CYP2C19 and CYP3A4. Amlodipine is a substrate of the isoenzyme CYP3A4, which increases the probability of the development of interaction between these drugs. The purpose of our study was to investigate antihypertensive efficacy of amlodipine in patients suffering from arterial hypertension combined with acid-dependent diseases and additionally taking omeprazole. Method: Study included a total of 150 patients with AH and ADD. Antihypertensive therapy was evaluated by means of office measuring of arterial pressure (AP) and circadian monitoring of AP (CMAP). The followed-up patients with AH and ADD were divided into 2 groups. Group One was composed of hypertensive patients undergoing pharmacotherapy with 10 mg amlodipine, whose condition required due to exacerbation of ADD administration of omeprazole at a dose of 20 mg for a period from 3 to 4 weeks. Group Two comprised hypertensive patients receiving antihypertensive therapy consisting of 10 mg amlodipine, who were found to have remission of acid-dependent diseases, with no additional medication taken. Results: The obtained findings demonstrated that one of the commonly used drug combinations in treatment of patients with AH and ADD in ambulatory conditions was a combination of omeprazole and amlodipine, accounting for 7.1%. The results of office measurement of arterial pressure (AP) 2 weeks after initiating pharmacotherapy with omeprazole in patients with AH and ADD demonstrated that the patients receiving omeprazole in addition to antihypertensive therapy were found to have a statistically significant decrease in systolic arterial pressure (SAP) and statistically significantly more pronounced dynamics of a decrease in diastolic arterial pressure (SAP) (p<0.05) compared with those not receiving therapy with omeprazole. Also, in the group of patients taking omeprazole, the findings of circadian monitoring of blood pressure (CMAP) showed a statistically significant decrease in average circadian SAP, average circadian DAP, mean value of daytime SAP and mean value of nighttime SAP (p<0.05). Conclusion: The obtained findings demonstrated that simultaneous prescription of amlodipine and omeprazole to patients with concomitant pathology, i.e., AH and ADD, turned out to enhance the antihypertensive affect of amlodipine, which probably resulted from substrate competition of amlodipine and omeprazole at the level isoenzyme CYP 3A4 of cytochrome P450.

© Copyright 2018, Mary Ann Liebert, Inc. 2018. Background: Rivaroxaban is metabolized in the liver via CYP3A4, the cytochrome involved in the metabolism of nearly 50% of all medications. Thus, its effective concentration depends on multiple pharmacologic parameters. Methods: The primary goal of our research was to study the correlation between the CYP3A family activity and the safety and efficacy of anticoagulant therapy with rivaroxaban in patients with deep vein thrombosis (DVT). Thirty one patients with DVT aged 21-83 years, 18 men and 13 women, received rivaroxaban (Xarelto) 30 mg/day for 21 days after diagnosis and 20 mg/day for the follow-up period of 6 months. During the study period, Doppler ultrasound was performed weekly to assess the clot dynamics and recanalization time. Results: We found a direct statistically reliable correlation between CYP3A4 activity and both peak and trough rivaroxaban levels. A correlation was also found between the initial clot length and the time to full recanalization r = 0.764 (0.554-0.883), p < 0.0001. No significant link was found between either the glomerular filtration rate and peak rivaroxaban concentrations or between CYP3A4 activity and the treatment effectiveness parameters. No connection between renal function and rivaroxaban concentration was established in our study, which agrees with the clinical trials data that allow unlimited rivaroxaban use in patients with glomerular filtration rate >30 mL/min. Conclusions: The direct link between the initial clot length and time to full recanalization that has been found means that patients with more advanced stages of thrombosis need more time to reach recanalization than their counterparts with a less severe condition.

© 2018 Sychev et al. Purpose: The aim of this study was to determine the impact of ABCB1 (MDR1) rs1045642 polymorphisms on the efficacy and safety of amlodipine in Caucasian patients. Patients and methods: The 12-week study included 100 patients. Patients with the newly diagnosed stage I–II hypertension (HT) were recruited to complete genotyping of the rs1045642 single-nucleotide polymorphism (SNP). The study design did not include a control group. Before treatment, all patients either did not undergo antihypertensive treatment at all or did not receive regular antihypertensive therapy. The initial dose was 5 mg/day. Four office blood pressure measurements, two 24-hour noninvasive ambulatory blood pressure measurements, and questionnaires of Tsvetov were used to evaluate the efficacy and safety of amlodipine. Results and conclusion: The highest antihypertensive effect in combination with the lowest incidence of adverse reactions was observed in the TT group, while patients with the CC genotype showed a low antihypertensive effect and the highest incidence of adverse effects. Patients with the CC genotype presented with adverse effects predominantly in the form of edema. A total of 33 patients reached the target blood pressure (SBP <140 mmHg; DBP <90 mmHg): two patients with the CC genotype (12%); 18 patients with the CT genotype (34%); and 13 patients with the TT genotype (43%). The intergroup differences were: CC vs CT, P=0.02; CC vs TT, P=0.02; and CT vs TT, P=0.05. The results of this study indicate the potential of pharmacogenetic testing for rs1045642 SNP when prescribing amlodipine for the first time in Caucasian patients with stage I–II arterial HT.
