BACKGROUND

Oral drugs against SARS-COV-2 have received emergency use authorization for the treatment of mild-to-moderate COVID-19 in nonhospitalized patients who are at high risk for clinical progression.

OBJECTIVES

To provide a clinical practice overview of first-generation oral antiviral agents against SARS-CoV-2.

CONTENT

Molnupiravir and nirmatrelvir/ritonavir have been authorized for use in nonhospitalized individuals with mild-to-moderate COVID-19 who are at high risk for progression. In clinical trials, molnupiravir reduced the frequency of hospitalization or death by 3% (relative risk reduction 30%), and nirmatrelvir/ritonavir by 6% (relative risk reduction 89%). Their use in clinical practice requires early administration, review of drug-drug interactions (nirmatrelvir/ritonavir), considerations of embryo-fetal toxicity (molnupiravir), and compliance with ingestion of a high number of pills. Knowledge gaps include the efficacy of these agents in vaccinated, hospitalized, or immunosuppressed individuals with prolonged SARS-CoV-2 persistence.

IMPLICATIONS

First-generation oral antivirals represent progress in therapeutics against SARS-CoV-2, but also pose new challenges in clinical practice. Further advances in the development of new drugs are required.
