PubMed, Google Scholar, EMBASE, ResearchGate scientific information network and elibrary.ru databases were used as search resources. The keywords used for the search were “gabapentin”, “mechanism of action”, “gabapentin targets”, “gabapentin pharmacodynamics”, “pharmacokinetics”, “pharmacokinetic parameters”, “neuropathic pain”, and “randomized clinical trials”. The depth of the search was 26 years (from 1998 to 2024). This review resulted in 87 literature sources.Results. Neuropathic pain (NeP) is one of the most common types of chronic pain, characterized by a high prevalence among people of the working age. Effective pharmacotherapy aimed at eliminating the pain syndrome is a key tool for improving the quality of life and preserving the work capacity of patients. Heterogeneity of etiologic factors involved in the genesis of NeP indicates the need to use drugs the analgesic effect of which is based on weakening the transmission of pain impulses in the CNS. In clinical trials, gabapentin has demonstrated efficacy in reducing the severity of pain in patients with postherpetic NeP, painful diabetic neuropathy and many other conditions accompanied by NeP. The dose of gabapentin 300 mg/day is the initial dose in the therapy of NeP and requires a further slow titration depending on the patient’s response to therapy and tolerability of the drug, especially in elderly and senile patients, as well as in patients with an impaired renal function. According to the published data, the most pronounced analgesic effect is achieved in the patients against the background of the gabapentin administration at a dose of 3600 mg/day.Conclusion. Gabapentin is the drug of choice in the management of patients with NeP of different etiology and intensity. A satisfactory safety profile and pharmacodynamic effects make gabapentin possible, despite the long history of its use, to remain a relevant drug used by a wide range of physicians, specialties, for pharmacotherapy of NeP patients.","PeriodicalId":513390,"journal":{"name":"Pharmacy & Pharmacology","volume":" 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140997186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 142 patients with LUTS, with an established BPH diagnosis (N40 according to ICD-10) were included in the study and underwent all stages. All patients received monotherapy with tamsulosin 0.4 mg/day for at least 8 weeks. An IPSS questionnaire with the definition of quality of life, a prostate ultrasound with the determination of the prostate volume and residual urine, as well as uroflowmetry, were used to evaluate the results of the treatment. Controls were performed at 2, 4 and 8 weeks from the start of the therapy. The carriage of polymorphic markers CYP3A4 (*1B, *22) and CYP3A5*3 was determined in patients; HPLC was used to determine drug concentrations in blood plasma and levels of cortisol and its metabolite 6-beta-hydroxycortisol in urine to assess the phenotypic activity of CYP3A.Results. No statistically significant associations between CYP3A phenotype (defined by CYP3A4 and CYP3A5 genotypes) and clinical parameters of the tamsulosin therapy efficacy and the safety assessment in the studied sample of patients were found (p >0.05).

The study of physiological processes occurring with the participation of NO, as well as the metabolism and pharmacodynamics of pharmacological agents from the group of NO donors, requires the introduction of accurate and reproducible methods for the quantitative determination of this metabolite in biological media.The aim of the study was to develop the HPLC-MS/MS methods for the quantitative determination of NO in various tissues of rats.Materials and methods. The indirect NO quantification was based on estimation of the level of more stable metabolites: nitrites and nitrates extracted from rat tissues by homogenization with water. The reduction of nitrates to nitrites was carried out using nitrate reductase. The derivatization of nitrites was based on a reaction with Griess reagent. The resulting azo dye was determined by HPLC-MS/MS using an Agilent InfinityLab Poroshell 120 EC-C18 4.6×100 mm, 2.7 μm analytical column. The total chromatographic analysis time was 12 minutes, and the analyte retention time was 6.1 minutes. The analytical range of the method was 0.1–100.0 nmol (in terms of nitrite) per 1 ml of plasma or tissue homogenate.Results. The developed a bioanalytical method was validated according to the following parameters: a selectivity, a matrix effect, a recovery degree, a sample transfer, an analytical range linearity, a lower limit of quantification (LLOQ), an intra- and inter-assay accuracy and precision, and a stability at all the stages of the analysis. To test the method, the NO content in the plasma, brain, heart, aorta and lungs of rats was determined.Conclusion. The developed bioanalytical HPLC-MS/MS methods fully meets the validation requirements. The metrological characteristics of the technique make it possible to highly accurately estimate the NO production in various tissues of rats, which is undoubtedly relevant and in demand in the study of pathological processes as well as the mechanism of action of pharmacological agents from the group of NO donors.","PeriodicalId":513390,"journal":{"name":"Pharmacy & Pharmacology","volume":" 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140998999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted on male rats of the Wistar line. The post-intoxication state was modeled by a single injection of ethanol (3 g/kg, intraperitoneally). 30 min after awakening, the animals were injected with a physiological solution, acetylcysteine (1 g/kg), ademetionine (100 mg/kg) or taurine (40 mg/kg). A zoosocial interaction test was performed 30 min after the administration.Results. Among the behavioral indicators investigated, the following were validated: the number of acts of freezing, their duration, the number of acts of sniffing in front, the number of acts of avoidance and the number of vertical stances without support (p <0.05 between the values of the negative and positive control groups in all cases). The administration of acetylcysteine, ademetionine and taurine reduced the number of freezing acts by 53.64, 7.27 and 24.51%, respectively (p <0.05 when compared with the indicator index in the animals from the positive control group in all cases).

The data from the authors’ previous scientific research on the analysis of the diuretic properties of certain types of medicinal plant raw materials, as well as individual substances of a phenolic nature isolated from them (simple phenols, flavonoids), were also reviewed.Results. It was determined that the diuretic activity of most of the medicinal plants used, is due to such groups of biologically active compounds as terpenoids (essential oils and saponins), simple phenols, flavonoids and anthracene derivatives related to the secondary metabolites. It has been shown that, despite the fact that many herbal diuretics have concomitant anti-inflammatory, antimicrobial, antiviral, antihistamine and other properties relevant from the point of view of etiology and pathogenesis of the disease, it is reasonable to use them as part of collections of medicinal plants and other combined medicinal herbal preparations, as this is in accordance with the global trend.

This study is a non-interventional, retrospective analysis of the electronic database records of Cursor Marketing LLC (Russia) about the announced by medical organizations and executed contracts for the purchase of direct oral anticoagulants (DOACs). The сonsumption was calculated on the basis of a DDD (defined-daily-dose) and estimated DDDTID (defined-daily-dose/1000-inhabitants/day) for each DOACs: rivaroxaban, dabigatran and apixaban. The Rosstat database available on its official website were used as a source of inhabitants data for the Russian regions.Results. A total of 57 866 records were entered into the analyzed databases of Cursor Marketing LLC (Russia) from 2017 to 2022, 47.38% of which indicated rivaroxaban as the drug being procured, 26.51% indicated dabigatran, and 26.11% indicated apixaban. Edoxaban was not procured by healthcare organizations. During the period investigated, there was an increase in the consumption of all DOACs studied, with a higher increase for apixaban (by an average of 284.6% per year), then rivaroxaban (by 144.8% per year) and, to a lesser extent, dabigatran (by 92.5% per year). The analysis of DOACs consumption in general showed that compared to 2017, the need for these drugs in medical organizations in 2022 increased by 18 times. The Urals Federal District consistently exceeds the national average in terms of DDTID consumption. Noteworthy is the consumption dynamics of the regions of the Central Federal District and the North-Western Federal District, which made it possible to achieve DDDTID values above the national average for 5 out of 6 observation years. The lowest rates of DOACs consumption were observed in the Volga Federal District, which, despite positive growth dynamics, failed to reach the national average values. A high level of consumption (>10 DDDTID) of rivaroxaban was noted for the Arkhangelsk region (2018) and the Nenets Autonomous District (in 2021), dabigatran – only for the Arkhangelsk region (in 2018). Many more regions reached high levels of the apixaban consumption, especially in 2021.Conclusion. Despite a number of limitations, the data on the volume of DOACs procurement can be used in the analysis of the consumption at both regional and national levels. When analyzing the DOACs consumption, the impact of COVID-19 pandemic and pharmacogenetic features of patients in different regions should be taken into account.

The study included 179 patients of the Moscow region with a first-diagnosed arterial hypertension (AH) of 1–2 degree, including 141 (78.8%) women and 38 (21.2%) men aged from 32 to 69 years. By a simple randomization method, the patients were randomly allocated into groups receiving irbesartan and valsartan as mono- or combination therapy with hydrochlorthiazide. After 3 weeks of this pharmacotherapy, the presence of rs4646994 Alu Ins / Del genetic polymorphism of the angiotensin-converting enzyme (ACE) gene and the minimum equilibrium concentration of angiotensin II receptor blockers (ARBs) were determined.Results. The patients treated with irbesartan, the D/D genotype carriers, were significantly less likely to reach the target BP and more likely to require a pharmacotherapy intensification compared to I/D heterozygotes (p=0.042 and p=0.058, respectively) and I/I homozygotes (p=0.011 and p=0.011, respectively). The patients treated with valsartan, the D/D genotype carriers, significantly more often reached the target BP and significantly less often required a pharmacotherapy intensification than the I/D genotype carriers (p=0.05 and p=0.05, respectively). Herewith, at the end of the study, according to the results of the office BP measurements and daily BP monitoring, the target BP achievement was not significantly correlated with the I/D polymorphism of the ACE gene.Conclusion. When personalizing the AH therapy in patients of the Moscow region, the genotype I/I carriers by I/D polymorphism of the ACE gene, can be recommended irbesartan in the form of mono- or bicomponent therapy as a starting therapy of ARBs; the D/D genotype carriers can be recommended valsartan. A more pronounced decrease in the daytime systolic BP (SBP), the daytime diastolic BP (DBP) and the nighttime SBP variabilities in the valsartan group of patients, the D allele carriers may indicate a more persistent effect of the antihypertensive therapy.","PeriodicalId":513390,"journal":{"name":"Pharmacy &amp; Pharmacology","volume":"84 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140482011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
