Early Oral Antivirals Reduce Risk of Post-COVID Condition, Study Finds

• The meta-analysis included nine observational studies with a total of 866,066 patients.

• Nirmatrelvir-ritonavir was evaluated in eight studies, and molnupiravir in two, with one study assessing both drugs.

• The pairwise meta-analysis demonstrated that early use of oral antiviral drugs significantly reduced the risk of PCC, with a risk ratio of 0.77 (95% CI 0.68–0.88).

• The network meta-analysis revealed that nirmatrelvir-ritonavir was potentially more effective than molnupiravir in reducing PCC risk, with a surface under the cumulative ranking curve (SUCRA) of 95.5% compared to 28.8% for molnupiravir.

The findings suggest that early intervention with oral antiviral drugs during the acute phase of COVID-19 can play a crucial role in preventing long-term complications associated with PCC. Nirmatrelvir-ritonavir, in particular, showed superior efficacy compared to molnupiravir, indicating it may be the preferred choice for reducing the risk of PCC.

The study supports the standardized administration of oral antiviral drugs in non-hospitalized COVID-19 patients according to current guidelines. This approach could significantly decrease the incidence of PCC, improving patient outcomes and reducing the strain on healthcare systems dealing with long COVID cases.

The early administration of oral antiviral drugs, particularly nirmatrelvir-ritonavir, during the acute phase of COVID-19 is effective in reducing the risk of developing post-COVID conditions. These findings underscore the importance of timely antiviral treatment to prevent long-term COVID-19 sequelae and advocate for adherence to current treatment guidelines.
