The effective treatment of chronic and multifactorial conditions, driven by the dysregulation of multiple interconnected pathways, such as cancer, autoimmune and metabolic disorders, cardiovascular and neurodegenerative diseases, is one of the most substantial challenges in contemporary pharmacology. 'Traditional' single-target-based treatment frequently shows limited effectiveness, as resistance to therapy develops or relapses occur. The rational use of MTDLs seems therefore a promising way to address the complexity of biological systems, feedback mechanisms, crosstalk, and molecular pathways. Many MTDLs have been successfully marketed to date. Moreover, plenty of them offer an additional benefit in comparison to 'traditional' treatment approaches. To assess whether the polypharmacological trend remains prevalent, we thoroughly analysed drugs approved in the years of 2023-2024 in Germany. Among 73 newly introduced substances, 18 are in line with the polypharmacology concept, including 10 antitumor agents, 5 drugs indicated for autoimmune disorders, 1 indicated for hand eczema, 1 antidiabetic (and anti-obesity) drug, and 1 modified corticosteroid.</p>","PeriodicalId":19947,"journal":{"name":"Pharmacological Reports","volume":" ","pages":"543-560"},"PeriodicalIF":3.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12066383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This prospective study evaluated associations between radial peripapillary capillary (RPC) vessel density (VD) and systemic treatment, age, hypoxia, D-dimer, and interleukin-6 (IL-6) levels in patients recovering from coronavirus disease 2019 (COVID-19) related pneumonia.</p><p><strong>Methods: </strong>Sixty-three individuals who were admitted to the hospital due to COVID-19 bilateral pneumonia underwent ophthalmic examination two months post-discharge. RPC VD was measured using optical coherence tomography angiography. Associations with age, arterial hypertension, and systemic treatment (dexamethasone, remdesivir, and oxygen therapy), oxygen saturation, D-dimer, and IL-6 levels were evaluated. The control group comprised 43 control participants with no history of COVID-19 who attended routine ophthalmic examinations.</p><p><strong>Results: </strong>No ophthalmic abnormalities were detected. RPC VD did not differ significantly with hypertension or systemic treatment with dexamethasone and remdesivir. However, patients receiving oxygen therapy had higher RPC VD. A borderline inverse correlation was observed between inferior RPC VD and age. There were no correlations between RPC VD and oxygen saturation. Significant inverse correlations were found between nasal RPC and mean RPC with D-dimer levels and between inferior RPC VD and IL-6 levels. No significant differences in RPC parameters were observed when comparing the COVID-19 group with controls.</p><p><strong>Conclusions: </strong>Hypertension or systemic treatment had no significant effect on RCP VD.
