Antivirals Are Already Established Drugs
Before we further explain the potential of the newly-developed antivirals against SARS-CoV-2, let’s first highlight that antivirals are already established drugs.
Oseltamivir (Tamiflu), for instance, is a common antiviral that can prevent the development of severe flu symptoms when given early and even shorten its duration. Doctors also prescribe antivirals to treat AIDS and Hepatitis C.
Come to think of it, remdesivir is a common drug for Hepatitis C. Experts simply repurposed it to work against COVID-19.
COVID-19 Medicine Update: 3 Newly Developed Antivirals
If things go as planned, the world might just have at least one antiviral against COVID-19 within a few months.
These medicines are molnupiravir by Merck & Co. and Ridgeback Biotherapeutics, PF-07321332 by Pfizer, and AT-527 by Roche and Atea Pharmaceuticals.
Scientific investigators said these drugs inhibit the virus’ ability to replicate in human cells. This inability to replicate or reproduce means three things:
- Less viral load
- Shortened duration of illness
- Prevention of drastic immune response that results in critical illness or death
Among the 3, Molnupiravir is the Top Contender
As for the COVID-19 medicine update, reports say among the three drugs, molnupiravir holds the strongest potential.
