Medical News: Researchers have been exploring new and existing drugs to manage the devastating effects of COVID-19. A recent clinical study conducted at the Egyptian Armed Forces Fever Hospital in Cairo, Egypt, has brought exciting findings to light. It focused on comparing the antiviral drug triazavirin (TZV) with the widely used oseltamivir (Tamiflu). The team, led by scientists from institutions like Ain Shams University and the Al-Galaa Military Medical Complex, aimed to determine which drug is more effective in reducing the severity and duration of the disease.

Medical News report delves into their findings, which shed light on how Triazavirin (TZV) significantly outperformed oseltamivir in key areas like hospital stay duration and recovery rates.
What is Triazavirin
Triazavirin, also known as Riamilovir, is a versatile antiviral medication originating in Russia. It was developed through collaboration between Ural Federal University, the Russian Academy of Sciences, Ural Center for Biopharma Technologies, and Medsintez Pharmaceutical. Unlike conventional nucleoside antiviral drugs, Triazavirin features a unique triazolotriazine core, marking it as a novel structural class of antiviral agents. Its primary mechanism involves disrupting the synthesis of viral RNA and hindering the replication of viral genomic fragments by mimicking purine nucleosides. Initially designed to combat pandemic influenza strains like H5N1, its broad-spectrum efficacy has been demonstrated against various pathogens, including tick-borne encephalitis and other severe viral infections.
Beyond influenza, Triazavirin is being explored for its potential against life-threatening conditions such as Ebola, Lassa fever, and secondary bacterial pneumonia. Having undergone clinical trials, it has shown significant antiviral activity against acute respiratory viral infections. In 2020, its use extended to battling SARS-CoV-2 in regions like Russia, China, and South Africa, further establishing its versatility. While the exact mechanism of its action remains under debate, its efficacy against a wide range of viruses highlights its promise as a critical tool in combating emerging infectious diseases.
Key Findings of the Study
The randomized, double-blind trial included 80 patients who were diagnosed with COVID-19. Participants were split into two groups: one received TZV (250 mg three times daily) alongside standard treatments, while the other was given oseltamivir (75 mg twice daily) with similar supportive care. The treatment period lasted seven days, and outcomes were monitored for eight days.
-Shorter Hospital Stays:
Patients in the TZV group had an average hospital stay of 6.1 days, compared to 8.4 days for those treated with oseltamivir.
-Improved Symptom Recovery:
Clinical symptoms such as fever, cough, and shortness of breath resolved 1.8 days faster on average in the TZV group. This speedier recovery reduces the strain on healthcare resources.
-Effective Pneumonia Treatment:
Using CT scans, 37.5% of patients in the
TZV group showed full recovery from pneumonia by the end of the treatment period, whereas none in the oseltamivir group reached this milestone.
-Viral Load Reduction:
By the end of the trial, only 15% of TZV-treated patients tested positive for COVID-19 via PCR tests, compared to 20% in the oseltamivir group, although this difference was not statistically significant.
-Safety and Tolerability:
Both drugs were well-tolerated, with no significant side effects reported. This indicates that both TZV and oseltamivir are safe for treating COVID-19.
A Closer Look at Triazavirin’s Mechanism
Triazavirin is a synthetic antiviral drug originally developed in Russia to combat influenza. It works by inhibiting the replication of viral RNA, which effectively halts the virus's ability to multiply and spread within the body. This multitarget mechanism is what makes it highly effective against a range of RNA viruses, including SARS-CoV-2, the virus responsible for COVID-19.
-Why Triazavirin Is Superior to Oseltamivir
Oseltamivir, though a well-known antiviral drug, primarily targets influenza viruses by blocking the neuraminidase enzyme, which helps release new viral particles. While it has been used off-label for COVID-19, its efficacy has been inconsistent. On the other hand, triazavirin's broad-spectrum antiviral action seems to address the challenges of COVID-19 more effectively.
Moreover, the study highlighted that TZV’s ability to cure chest pneumonia - a critical and often fatal complication of COVID-19 - sets it apart from oseltamivir. This is a significant breakthrough in managing severe cases of the disease.
Implications for Healthcare Systems
Shorter hospital stays and faster symptom recovery are not just beneficial for patients - they also ease the burden on overwhelmed healthcare facilities. This is particularly crucial during surges in COVID-19 cases when hospital resources are stretched thin. By facilitating quicker recoveries, TZV could play a vital role in managing future pandemics.
Study Limitations and Future Directions
While the study results are promising, they also point to the need for further research. Larger, multicenter trials involving diverse patient populations could validate these findings. Additionally, exploring the long-term effects of TZV treatment, as well as its efficacy in elderly or immunocompromised patients, would provide a more comprehensive understanding of its potential.
Conclusion
The findings from this study underscore triazavirin's superiority over oseltamivir in managing COVID-19. With shorter recovery times, better pneumonia outcomes, and a similar safety profile, TZV stands out as a promising candidate for treating the disease. Its broad-spectrum antiviral activity also makes it a valuable addition to the arsenal against respiratory viruses.
As we continue to navigate the challenges posed by COVID-19, innovative treatments like triazavirin offer hope for improving patient outcomes and alleviating the strain on healthcare systems.
