This cross-sectional study involved 125 unrelated healthy Saudis ages 18–60 years visiting the King Abdulaziz University Hospital (KAUH) in Jeddah, Western Saudi Arabia. The Oragene™ DNA saliva collection kits were used to collect and extract DNA from saliva samples. A polymerase chain reaction-restriction fragment length polymorphism analysis was used to detect the mutant alleles. Over 51.4% of the Saudi participants carried one or more mutant alleles. The frequency of the VKORC1 (-1639G>A) allele in Saudi was relatively high at 54.8%. The frequencies of the CYP2C9 allele were 19.6% and 54% for the CYP2C9*2 and CYP2C9*3 alleles, respectively, which are substantially more abundant than in other populations. The observed high frequencies of VKORC1 (-1639G>A) and CYP2C9*2 and CYP2C9*3 polymorphisms suggest that genetic testing should be considered before initiating warfarin therapy to predict the optimal initial dose of warfarin and minimize warfarin-related side effects.","PeriodicalId":16761,"journal":{"name":"Journal of Pharmacology & Pharmacotherapeutics","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45070715","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}

Adult male Wistar rats (8 weeks of age) received an HS (8.0% NaCl) or normal sodium (NS; 1.3% NaCl) diet and NAC (600 mg/L) in drinking water or normal water. At 11 weeks of age, the rats underwent a renal I/R procedure. They followed for 10 weeks after I/R, at the 1st, 2nd, 4th, and 10th weeks, in which tail blood pressure (tBP) and renal function were evaluated. And renal renin gene expression was evaluated in the 10th week after I/R. During the study, it was observed that the tBP remained consistently higher in the HS-I/R+water group compared to the NS-I/R+water group. However, in the early weeks following I/R (1st, 2nd, and 4th weeks), the tBP was lower in the HS-I/R+NAC group than in the HS-I/R+water group. In the 10th week after I/R, the serum creatinine levels were higher in both the HS-I/R+NAC and NS-I/R+NAC groups compared to the HS-I/R+water and NS-I/R+water groups. Conversely, the creatinine clearance was higher in the HS-I/R+NAC group than in the HS-I/R+ group in the 2nd week following I/R. Additionally, the urinary protein levels were higher in the HS-I/R+NAC group than in the NS-I/R+NAC group in the 10th week after I/R. It was also observed that NAC treatment resulted in increased renal renin gene expression in the 10th week following I/R. After renal I/R in animals given HS, NAC treatment was initially effective in lowering blood pressure or increasing creatinine clearance. However, these positive effects did not persist over the long term, resulting in decreased kidney function and increased blood pressure. Furthermore, the renin-angiotensin-aldosterone system was increased by HS intake, and the benefits of the NS diet were less effective than those of the HS diet. Thus, NAC provides temporary protection only in the early stages following an insult.","PeriodicalId":16761,"journal":{"name":"Journal of Pharmacology & Pharmacotherapeutics","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"65432638","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 rationalization of antimicrobial doses in clinical studies is crucial for preventing AMR. This review analyzes how rationalization tactics affect AMR and gut microbiota in clinical studies. Studies that provided data on the use of antibiotics, AMR, or gastrointestinal microbiota were taken into account for the current review. The AMR rate was found to be low when healthy gut flora was maintained using various antibiotic rationalization techniques, such as limited use of antibiotics or targeted treatments. However, the effectiveness of these strategies differed based on the particular intervention, the research population, and the length of the course of therapy. The rationalization of antibiotic prescriptions in clinical research is one potential method for reducing the prevalence of AMR by maintaining the gut flora. Rationalization techniques may help lower AMR rates and foster the development of good intestinal flora. This review describes various antibiotic rationalization techniques and the importance of maintaining healthy microbial flora to minimize AMR-associated health issues.","PeriodicalId":16761,"journal":{"name":"Journal of Pharmacology & Pharmacotherapeutics","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47226366","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}

Methods Cells expressing human (h) or rat V1a, V1b, V2, or oxytocin receptors (OTR) were incubated with varying concentrations of OCE-205 or with arginine vasopressin (AVP), and responses were measured with fluorescence or reporter gene assays. In addition, human resistance arteries were exposed to increasing concentrations of OCE-205, and the resulting contractility was measured. Results The mean efficacy of OCE-205 at hV1aR was 39% of the maximal possible effect (MPE), with a mean EC50 of 0.71 nM. Above 1 nM OCE-205, the percent maximal possible effect (%MPE) plateaued. The EC50 was much higher at hV1bR (134 nM), hV2R (420 nM), and OTR (6.9 nM), indicating selectivity for hV1aR. Results at rat receptors were similar. OCE-205 produced 40.0% of maximal depolarization-induced contraction, demonstrating functional partial agonism. Conclusion The dual agonist/antagonist structure of OCE-205 thus allows it to act as a highly selective partial agonist at vasopressin V1aR at therapeutically relevant concentrations.","PeriodicalId":16761,"journal":{"name":"Journal of Pharmacology & Pharmacotherapeutics","volume":"14 1","pages":"54 - 61"},"PeriodicalIF":0.2,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42769858","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}

To address these issues, educators have advocated the use of virtual reality and mannequins to teach clinical pharmacology. Objectives To study the effect, perception, and feedback of virtual reality high-fidelity adult mannequin-based (VHFM) simulation of real-life clinical scenarios over conventional tutorials in teaching clinical pharmacology to medical students. Material and Methods An interventional study was designed for 2nd year MBBS students for a period of 6 months. The enrolled students were randomly assigned to the test group (VHFM) or control group (tutorials). The CAE Healthcare Ltd. maestro, high-fidelity prehospital mannequin (APOLLO) was used in the test group. Three sessions consisting of six different cases were discussed, and multiple-choice questions (MCQs)-based pre-test, post–test, and retest after a month were conducted in both groups and compared. The perception and feedback of faculty and students were obtained by using a modified and revalidated questionnaire. Results The test group outperformed the control group (p <.001) in all sessions based on pre-test, post-test, and retest scores, and within-group comparisons revealed significant improvements in both groups. Students’ perceptions and feedback regarding VHFM were more enthusiastic and promising than in the tutorial group. Conclusions VHFM is student-centered, provides an active learning environment, and aids in skill development. We strongly suggest VHFM-based learning as a complement to traditional teaching strategies in pharmacology, especially for teaching clinical reasoning to medical students.","PeriodicalId":16761,"journal":{"name":"Journal of Pharmacology & Pharmacotherapeutics","volume":"14 1","pages":"25 - 34"},"PeriodicalIF":0.2,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42213238","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}
