Pfizer PAXLOVID : What Is It?

Pfizer PAXLOVID is an antiviral treatment that consists of two protease inhibitors :

  • two 150 mg tablets of Nirmatrelvir (the new protease inhibitor developed by Pfizer)
  • one 100 mg tablet of Ritonavir (an old antiviral approved in 1996)

Protease inhibitors work by binding to proteolytic enzymes used by the SARS-CoV-2 virus to replicate. This prevents the virus from replicating in the infected cells, stopping the infection and preventing transmission.

Drug combinations like this offer a synergistic effect, above and beyond their individual abilities. In this combination, ritonavir helps to slow down the breakdown of nirmatrelvir, allowing it to remain in the body for a longer period at higher concentrations.

PAXLOVID was first given an Emergency Use Authorisation (EUA) by the US FDA on 22 December 2021, for the treatment of mild to moderate COVID-19 in adults and children 12 years and older.

It is meant to be taken by those who are at high-risk of developing severe COVID-19, and must be taken within 5 days of symptom onset. In addition, PAXLOVID must not be taken for more than 5 consecutive days.

The EPIC-HR trial showed that PAXLOVID is able to reduce the risk of hospitalisation or death from COVID-19 b y 88%, compared to placebo.

Individuals who took PAXLOVID have reported side effects like impaired sense of taste, diarrhoea, high blood pressure and muscle aches.
