ABSTRACT
BACKGROUND:
Oral drugs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have received emergency use authorization for the treatment of mild-to-moderate COVID-19 in non-hospitalized 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. SOURCES References for this review were identified through searches of PubMed, Google Scholar, bioRxiv, medRxiv, regulatory drug agencies, and pharmaceutical companies' websites up to 16 February 2022. CONTENT Molnupiravir and nirmatrelvir and 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 and ritonavir by 6% (relative risk reduction 89%). Their use in clinical practice requires early administration, review of drug-drug interactions (nirmatrelvir and 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.Keywords
