Patients were grouped by the antiviral drug received. The primary endpoint was the length of hospital stay. Patients were further divided into subgroups for stratified analysis, considering age, timing of medication, and drug mechanisms, to explore whether these factors could influence the treatment efficacy.<br/><strong>Results:</strong> Of the enrolled 195 patients receiving any treatment, 42 received Nirmatrelvir/Ritonavir, 33 received Molnupiravir, 81 received Simnotrelvir/Ritonavir, and 39 received Azvudine. Patients in Nirmatrelvir/Ritonavir and Simnotrelvir/Ritonavir groups had significantly shorter hospital stays compared to those in Azvudine group (<em>P</em> &lt; 0.05). No significant difference was observed in hospital stays between those initiating antiviral therapy within or more than five days after symptom onset (<em>P</em> = 0.1109). Among patients with comorbidities, the Nirmatrelvir/Ritonavir and Simnotrelvir/Ritonavir group showed shorter hospital stays than the Azvudine group (<em>P</em> &lt; 0.05). No serious treatment-related adverse events were observed across the groups.<br/><strong>Conclusion:</strong> In this retrospective study, Nirmatrelvir/Ritonavir and Simnotrelvir/Ritonavir exerts stronger potency on reducing duration of hospital stays in hospitalized patient with COVID-19, suggestive of a better choice for antiviral therapy. Patients who fail to take antiviral drugs in time after symptom onset would still benefit from these antiviral regimens. Additional well-designed clinical trials with large sample size are still needed to further confirm the effectiveness of these antivirals.<br/><br/><strong>Keywords:</strong> antivirals, COVID-19, molnupiravir, simnotrelvir/ritonavir, azvudine, nirmatrelvir/ritonavir<br/>","PeriodicalId":13577,"journal":{"name":"Infection and Drug Resistance","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
