This study aimed to determine the association of early use of oral antiviral drugs (including nirmatrelvir-ritonavir and molnupiravir) with the risk of post COVID-19 condition (PCC) and compare the possible efficacy of nirmatrelvir-ritonavir and molnupiravir. PubMed, Web of Science, Embase, Cochrane, MedRxiv, and Psycinfo were searched from inception until November 1, 2023. We included studies that assessed the effect of oral antiviral drugs on the incidence of PCC. Pairwise and network meta-analyses were conducted using a random-effects model. Risk ratios (RRs) for oral antiviral drugs were calculated with a confidence interval (CI). Nine observational studies containing 866,066 patients were included. Nirmatrelvir-ritonavir and molnupiravir were evaluated in eight and two studies respectively, with both drugs evaluated in one study. Pair-wise meta-analysis showed that early oral antiviral drugs reduced PCC risk (RR 0. 77, 95% CI 0. 68-0. 88). Network meta-analysis showed that nirmatrelvir-ritonavir may perform better than molnupiravir (surface under the cumulative ranking curve: 95. 5% vs. 31. 6%) at reducing PCC risk. Early use of oral antiviral drugs may potentially protect against developing PCC in non-hospitalized patients with COVID-19. These findings support the standardized administration of oral antiviral drugs in patients during the acute phase of COVID-19 according to the guidelines.
