Safety and Efficacy of Antiviral Drugs for the Treatment of Patients with SARS-CoV-2 Infection: A Systematic Review and Meta-analyses
Abstract
Objective
To systematically review the safety and efficacy outcomes of using antivirals for the treatment of COVID-19.
Methods
Five databases were screened from inception to 27-Aug-2020. The effects of specific drug interventions on safety and efficacy were assessed in COVID-19 patients. Risk Ratios (RRs) with corresponding 95% confidence intervals (CIs) were pooled using random-effects models.
Results
A total of 10 studies were identified which fulfill the inclusion criteria. Patients taking antivirals had 26% less risk of having a severe adverse event (SAE) compared to controls (RR, 0.74, CI:0.62 to 0.89, P=0.002). Clinical improvement at day 14 was observed among the cases treated with antivirals compared to the control group (RR 1.24, CI: 1.00 to 1.53 p=0.05).
Conclusion
There is evidence that Remdesivir and LPV/r reduces the hospital length of stay and that patients to which antivirals were administered had less SAE and improvement when compared to patients not prescribed with antivirals. Due to a lack of power and the quality of the studies, it was not possible to determine which antivirals have a greater risk-benefit balance, and therefore the optimal approach to antiviral treatment is still uncertain.
