Molnupiravir: Oral COVID-19 Antiviral Treatment
Molnupiravir is an oral direct-acting antiviral agent developed specifically for the treatment of COVID-19. Its mechanism of action is unique: it acts as a ribonucleoside analog that induces "error catastrophe" during viral RNA replication. The accumulation of copying errors renders the virus non-viable and halts its proliferation.
The drug helps prevent the progression to severe disease and reduces the risk of hospitalization. On Unifarm, you can find a list of medications (including Lagevrio and generics) containing this active ingredient.
Indications
- Mild to Moderate COVID-19: In adult patients with a positive SARS-CoV-2 test result.
- High-Risk Patients: Prescribed for individuals with at least one risk factor for developing severe illness (e.g., elderly age, obesity, diabetes mellitus, heart disease).
