Abstract:
The coronavirus disease 2019 (COVID-19) pandemic has become a global public health crisis, for which antiviral treatments are considered mainstream therapeutic approaches. With the development of this pandemic, the number of clinical studies on antiviral therapy, including remdesivir, chloroquine and hydroxychloroquine, lopinavir/ritonavir, ribavirin, arbidol, interferon, favipiravir, oseltamivir, nitazoxanide, nelfinavir, and camostat mesylate, has been increasing. However, the efficacy of these antiviral drugs for COVID-19 remains controversial. In this review, we summarize the recent progress and findings on antiviral therapies, aiming to provide clinical support for the management of COVID-19. In addition, we analyze the causes of controversy in antiviral drug research and discuss the quality of current studies on antiviral treatments. High-quality randomized clinical trials are required to demonstrate the efficacy and safety of antiviral drugs for the treatment of COVID-19.
Insights
The efficacy of antiviral drugs for COVID-19 remains controversial. High-quality clinical trials are needed to confirm the safety and effectiveness of these coronavirus disease 2019 treatments.
Area of Science:
- Virology
- Infectious Diseases
- Pharmacology
Background:
- The COVID-19 pandemic necessitated rapid development of antiviral treatments.
- Numerous antiviral agents have been investigated for treating coronavirus disease 2019.
- The clinical effectiveness of these antiviral therapies remains a subject of debate.
Purpose of the Study:
- To review recent findings on antiviral therapies for COVID-19.

- To assess the quality of existing studies on antiviral treatments for coronavirus disease 2019.
Main Methods:
- Literature review of clinical studies on antiviral drugs for COVID-19.
- Analysis of factors contributing to controversial results in antiviral research.
- Evaluation of the methodological quality of published trials.
Main Results:
- The efficacy of many antiviral drugs, including remdesivir and hydroxychloroquine, for COVID-19 is not definitively established.
- Inconsistent study designs and methodologies contribute to conflicting findings.
- A significant portion of current research lacks the rigor of high-quality randomized clinical trials.
Conclusions:
- The effectiveness and safety of antiviral treatments for COVID-19 require further rigorous investigation.
- High-quality randomized clinical trials are essential to resolve controversies and guide clinical practice.
