Insights
Remdesivir, an antiviral drug, is being studied for its effectiveness against coronavirus disease 2019 (COVID-19). Clinical trials and compassionate use are exploring its role in treating hospitalized patients with COVID-19.
Area of Science:
- * Virology and Infectious Diseases
- * Pharmacology and Therapeutics
Background:
- * The emergence of coronavirus disease 2019 (COVID-19) as a global pandemic necessitates urgent therapeutic strategies.
- * Remdesivir, a nucleotide analog, is under investigation for its antiviral properties against SARS-CoV-2, the virus causing COVID-19.
Purpose of the Study:
- * To review the development and mechanism of action of remdesivir.
- * To summarize its use in COVID-19 patients under compassionate use and clinical trials.
- * To assess the efficacy of remdesivir in treating COVID-19.
Main Methods:
- * Literature review of remdesivir's journey, mechanism, and clinical applications.
- * Analysis of data from compassionate use cases and ongoing clinical trials for COVID-19 treatment.
Main Results:
- * Remdesivir functions by inhibiting the RNA-dependent RNA polymerase of SARS-CoV-2.
- * Initial emergency use authorization was for severe COVID-19, now expanded to all hospitalized patients.
Conclusions:
- * Remdesivir is an evolving therapeutic option for COVID-19.
- * Its application has broadened from severe cases to all hospitalized patients under emergency use authorization.
Background:
Since its initial start in December 2019 at Wuhan, China, the coronavirus disease 2019 (COVID-19) has been rapidly spreading and labelled as a pandemic by the World Health Organization. The rate of human to human transmission of COVID-19 is far higher than severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome coronavirus (MERS). With no drugs or vaccines approved for the treatment of the disease, physicians have been using pre-existing drugs to curb the disease. One potential anti-viral agent currently undergoing numerous clinical trials is remdesivir, a nucleotide analog that inhibits RNA-dependent RNA polymerase of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Objective:
In this mini-review, we provide an overview of remdesivir's journey, mechanism of action, pharmacokinetics, used in patients with COVID-19 under compassionate use principle and clinical trials to understand the effect of remdesivir in the treatment of patients with COVID-19.
Conclusion:
Initially, remdesivir was granted an emergency use authorization (EUA) by the U.S. Food and Drug Administration for the treatment of COVID-19 with severe disease. But now, remdesivir has been granted for use under EUA to treat all hospitalized COVID-19 patients, irrespective of their severity of disease.
