Nowadays, it is very important to put an emphasis on widely understood teamwork. This is of great importance for achieving and maintaining success in all areas, especially in medicine. This kind of unity has many advantages, including unique ideas that are very helpful in a competitive environment, improve performance and knowledge, and create stronger supportive work relationships. Patient’s health can be improved by using comprehensive treatment. This provides an urgent need for multidisciplinary partnership in the medical community. Optimal pharmacological treatment is crucial to achieving treatment goals. To ensure excellent quality of medical care, interprofessional cooperation between physicians and pharmacists and/or other medical professionals is necessary. Their complementary knowledge and experience can lead to improved health outcomes and can also reduce treatment costs. There are also many barriers and difficulties in legal systems that would allow for more effective inter-professional cooperation. The COVID-19 pandemic contributed to emphasizing the role of the pharmacist, increasing powers, and at the same time to teamwork, sometimes forced by the situation. The purpose of this publication is to view the literature on the cooperation of physicians and pharmacists in the provision of medical services for patients. Professional cooperation has been well known in many countries for years, as it is a key medium supporting optimized patient care. Analyzing the challenges and approaches can lead to better and improved health care.

Purpose: P2Y₁₂ receptor inhibitors are drugs that decrease the risk of stent thrombosis and lower the long-term risk of non-stent-related myocardial infarction and stroke. They inhibit the binding of adenosine diphosphate (ADP) to the P2Y₁₂ receptor and effectively reduce platelet reactivity. However, considerable variability in the pharmacodynamics response contributes to a failure of antiplatelet therapy; this phenomenon is especially notorious for older drugs, such as clopidogrel. Some genetic polymorphisms associated with these drugs’ metabolic pathway, especially in the CYP2C19 gene, can significantly decrease antiplatelet efficacy. There are few reports on the variability stemming from the target of this drug class that is the P2Y₁₂ receptor itself. Results and conclusion: This review summarizes the results of research that focus on the influence of P2Y₁₂ genetic polymorphisms on the pharmacodynamics and the efficacy of P2Y₁₂ inhibitors. We found that the conclusions of the studies are unequivocal, and despite several strong candidates, such as G52T (rs6809699) or T744C (rs2046934), they may not be independent predictors of the inadequate response to the drug. Most probably, P2Y₁₂ genetic polymorphisms contribute to the effect exerted by other gene variants (such as CYP2C19*2/*3/*17), drug interactions, or patient habits, such as smoking. Also, epigenetic modifications, such as methylation or miRNA levels, may play a role in the efficacy of antiplatelet treatment.

Despite a higher safety profile compared to vitamin K antagonists, rivaroxaban therapy is still connected with multiple adverse effects, such as a high risk of bleeding. Thus, therapeutic drug monitoring (TDM) of rivaroxaban concentrations is suggested. An alternative to plasma samples can be dried blood spots (DBS), which minimize the cost of sample storage and transport. In this study, we developed a UPLC-MS/MS method for the analysis of rivaroxaban in DBS and plasma samples. Chromatographic separation was achieved on a Zorbax Eclipse Plus C18 column (2.1 × 100 mm; 3.5 µm, Agilent Technologies Inc., Santa Clara, CA, USA) with a mobile phase consisting of water and acetonitrile, both containing 0.1% formic acid. The analytes were detected using a positive ionization mode by multiple reaction monitoring. We validated the method according to ICH guidelines. The precision and accuracy were satisfactory. Extraction recovery was approximately 57% and 66% for DBS and plasma samples, respectively. A high correlation between rivaroxaban concentrations in plasma and DBS samples collected from patients was confirmed with Deming regression. The suitability of both sampling techniques for the rivaroxaban TDM was also verified by Bland–Altman plots based on DBS-predicted and observed plasma concentrations. In addition, we found a significant relationship between rivaroxaban concentrations and coagulation parameters, including prothrombin time (PT) and international normalized ratio (INR).

Purpose: Interindividual variability in rivaroxaban exposure remains incompletely understood and may contribute to differences in treatment outcomes. This study aimed to investigate associations between polymorphisms in CYP3A4 (rs2242480), CYP2J2 (rs890293), and ABCB1 (rs1045642, rs2032582) genes, clinical factors and rivaroxaban pharmacokinetics. Methods: The study included 66 patients receiving 20 mg of rivaroxaban once daily. Rivaroxaban concentrations in plasma and dried blood spots were determined using a validated UPLC-MS/MS method. Genotyping was performed using PCR-RFLP. Associations between pharmacokinetic parameters, genetic variants and anthropometric characteristics, concomitant medications, comorbidities, and coagulation parameters were assessed using appropriate statistical analyses. Results: Carriers of the ABCB1 rs2032582 G allele exhibited lower rivaroxaban exposure, as reflected by reduced AUC_0–12h values compared with non-carriers (1817.43 ± 703.70 vs. 2442.96 ± 691.13 ng·h/mL, nominal p = 0.0369). Concomitant use of eplerenone was associated with increased rivaroxaban exposure. Body mass composition and impaired renal function were associated with rivaroxaban concentrations. In addition, associations between CYP3A4 rs2242480 genotype and several body size descriptors, including body weight or lean body mass, and selected coagulation parameters were observed in exploratory analyses. However, most nominal associations did not remain statistically significant after correction for multiple comparisons. After Benjamini–Hochberg correction, only impaired renal function, drug interactions and biological sex remained statistically significant factors, impacting rivaroxaban’s pharmacokinetics and anticoagulant parameters. Conclusions: Several genetic and clinical factors showed nominal association with rivaroxaban pharmacokinetics and coagulation parameters in this study. These findings should be interpreted as exploratory given the limited sample size and the number of statistical comparisons. Further studies in larger cohorts are needed to clarify the clinical relevance of genetic and clinical determinants of rivaroxaban exposure.

Background: The number of publications related to rivaroxaban is growing, making it difficult for scientists to review relevant materials. Objectives: This bibliometric analysis is focused on highlighting hot spots and new trends associated with rivaroxaban studies and provides references and guidance for further research. Methods: A comparison between countries, journals, authors, and organizations was performed. Microsoft Excel 2021 and VOSviewer were used to process and visualize data extracted from Web of Science. The time range was set from 1991 to late 2024. A total of 6979 articles were analyzed and bibliometric maps of co-citations of references and co-occurrences of the keywords were built. Results: Relative research interest increased until 2021, when it started to drop. The new trends in publications related to rivaroxaban are associated with a comparison of NOAC therapy outcomes with previously used vitamin K antagonists (warfarin). The research was focused also on new NOAC representatives, medical conditions treated with NOAC, and safety of the therapy. New trending topics are related to ABCB1, peripheral artery disease, direct-acting oral anticoagulants, PCI, and SARS-CoV-2. Conclusions: This bibliometric analysis showed that increasing attention is being paid to the medical conditions treated with NOACs and issues related to the safety of this therapy.

Aim: We aimed to define the influence of P2Y12 polymorphisms (rs6801273, rs2046934, and rs6809699), diabetes, hypertension, obesity, hypercholesterolemia, statins intake, and smoking habit on clopidogrel therapy in patients undergoing percutaneous coronary intervention. Materials & methods: We used PCR-RFLP and PCR-ASO for P2Y(12) genotype analysis. The effectiveness of the therapy was measured with the VerifyNow method and defined in platelet reactivity units. Results: Studied polymorphisms had no statistically significant influence on PRU before (PRU0) and 6 months (PRU6) after the procedure. H1/H1 diabetic carriers had significantly higher PRU6 values than patients without diabetes. Obese H1/H2 subjects had significantly lower PRU6 values than H1/H2 non-obese carriers. Conclusion: We found that obesity and diabetes may influence the long-term outcome of antiplatelet therapy.
