The Oral Antiviral Race Is Heating Up
While Merck and Pfizer are gearing up to deliver their experimental COVID‑19 pills, other players are scrambling to launch what they claim will be the next big leap in oral treatment—faster, easier, and—god forbid—safer.
Who’s In the Race?
- Enanta Pharmaceuticals: Proud of their coronavirus‑specific design.
- Pardes Biosciences: Already rolling over early‑stage trials.
- Shionogi & Co Ltd (Japan): Big‑scale trials slated for the end of the year.
- Novartis AG: Still in the lab, testing pills on animals.
Challenges on the Horizon
Antivirals need to punch at the virus after it’s already inside our cells, all while sparing our healthy ones. Timing is also everything—early treatment is the name of the game.
What Experts Are Saying
Dr. Robert Schooley from UC San Diego smiles and says, “If you’re not vaccinated, your protection is gone. If you can’t get a shot, you’re still stuck. We need a pill on tap that works.”
In a nutshell: vaccines still reign suprema, but a convenient oral remedy would be a welcome side‑kick for anyone fighting the illness.
Commercial Outlook
Industry analysts predict that a successful pill could fetch well over $10 billion per year—about 13 billion Singapore dollars—once it’s in the market. Merck’s own drug, molnupiravir, could shell out roughly $700 per treatment course, thanks to a government contract.

p*{Atea’s once‑prepped-for‑hepatitis‑C drug is now fighting COVID‑19 by chasing the virus’s copy‑cat engine. The plan? Stall the viral replication factory before it gets a chance to spin out copies. Think of it as a detective arresting a troublemaker right at the crime scene.}

p*{Pfizer’s pill, alongside a dose of older cousin ritonavir, fights the virus in its earlier stage by blocking a crucial enzyme.
Listen up: the pill needs ritonavir to stay in your bloodstream longer, but it can raise tummy troubles and mess with other medicines.

Jay Grobler says it can stay handy for future respiratory foes:

p*{Combat-sun records show there are several players:
el*{Pardes, with Gilead science funding, is taking the virus head-on with a once‑ or twice‑daily dose—no ritonavir needed.}

h3*{A Word on Safety & Side‑Effects}
p*{Pfizer’s booster can cause stomach upset, but its effect on other meds isn’t a trivial story.
Merck’s gel? Men need to skip the lovey‑dovey and optionally use contraception—no reason to skip your empire building.
And while Gilead’s oral remdesivir (the one that also went back to hepatitis‑C roots) sits on the market with IV successes for hospitalized individuals, they’re still tuning it for pills—talk about a slide‑away.}

h3*{What Comes Next?}
p*{So what’s on the horizon? Researchers are checking once‑ or twice‑daily dosage schedules, testing whether boosters are truly indispensable, and watching the courtship of the next-generation antivirals.
This drama is proof that even in a global health crisis, old drugs can get a makeover, and new science keeps rewriting the playbook.
