🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively inhibiting the RNA-dependent RNA polymerase enzyme of certain RNA viruses. By mimicking the natural substrate, it gets incorporated into the viral RNA chain and prevents further elongation, thereby stopping viral replication. This action is specific to viral enzymes and does not significantly affect human DNA or RNA polymerases at therapeutic concentrations.
