Paxlovid is a combination of Nirmatrelvir, an antiviral medication, which is designed to stop the virus from spreading into the body, and medicine Ritonavir, which works like a booster that increases the existence of Nirmatrelvir in the body to enhance the effectiveness of this combination medication.

The FDA has authorized the emergency use of Paxlovid to treat mild-to-moderate COVID-19 in adults and children (aged 12 years and older, weighing at least 40kg), with a positive test for SARS-CoV 2, who are at risk for progression to disease including hospital stay and death.

Also the medicine is only indicated withing 5 days of the onset of signs/symptoms of Coronavirus disease (COVID-19). 

The FDA-approved COVID-19 medicine had demonstrated 89% efficacy in phase 2 & 3 clinical trials when given within 3 days of symptoms, and as per an US study it reduced hospital stay or death by 49% in a highly vaccinated group of individuals of beyond 50 years of age.

Notably, the clinical trials of medicine has demonstrated that it works effectively in vaccinated people, too, as 90.3% of people in the US study had 3 or more vaccine doses. It may be significant for a small group of those who get infected and may develop severe complications, despite a very high COVID-19 coverage in India.

Paxlovid and Its Efficacy Against All Variants of COVID-19:

Paxlovid has seeken much attention across the globe over the last several months as it demonstrated efficacy and promising outcomes against all variants of SARS CoV 2, including Omicron variant and its different sub-variants which have shown immune escape features and are capable of cursing repetitive infection.

The antiviral medicine is useful across all variants of COVID-19. It is effective for all those who have risk factors for developing severe disease. The antiviral medicine Paxlovid reduced the risk of hospital stay or death from SARS-CoV-2 Omicron variants in older individuals by 44%.

According to Dr Gagandeep Kang, a virologist and who teaches at the Christian Medical College, Vellore, “As the virus has evolved to escape immunity, the monoclonal antibody therapies no longer work.” So, Paxlovid is the only significant antiviral we have, since medicine Molnupiravir (another drug widely used for COVID-19 disease) seems to be not as much as good and has a few safety concerns.
