How Remdesivir 100 mg Works

Remdesivir 100 mg works by stopping SARS‑CoV‑2 from making RNA. Remdesivir 100 mg changes inside cells, into a version that acts like a building block used by the virus when it makes RNA. The active version works with the RNA polymerase, an enzyme needed for copying.

When the viral polymerase is affected the virus has trouble making the RNA it needs to make virus particles. Remdesivir does not directly remove all symptoms of COVID‑19. Instead Remdesivir attacks the virus itself. The patients immune system the stage of the disease, age, risk factors and other health issues can all affect how the illness goes.

Antiviral treatment works best when given in the infection. For high‑risk outpatients CDC guidance says that Remdesivir should start soon as possible and within the recommended time after symptoms start.

Mechanism of Action of Remdesivir

The active form of Remdesivir targets the polymerase enzyme of SARS‑CoV‑2. This enzyme is needed for the virus to copy its RNA. The active form acts like a building block. Remdesivir can stop the making of RNA.

This is important because SARS‑CoV‑2 is an RNA virus. Its ability to make copies depends on copying its material. By stopping this process Remdesivir can reduce how much the virus makes.

Remdesivir does not work like antibiotics. Antibiotics attack bacteria, whereas Remdesivir stops virus replication. Therefore, Remdesivir should not be used to treat infections. The benefit of Remdesivir can also depend on when Remdesivir starts. Current CDC guidance says that Remdesivir for high‑risk patients should help lower the chance of getting worse.
