Which of the following antiviral medications inhibits neuraminidase enzyme?
Acyclovir
Oseltamivir
Efavirenz
Rilpivirine.
The Correct Answer is B
This is because oseltamivir is a neuraminidase inhibitor, which means it blocks the enzyme that helps the influenza virus to spread from cell to cell. By preventing the release of new virus particles, oseltamivir reduces the duration and severity of influenza infection.
Choice A is wrong because Acyclovir is wrong because it is a nucleoside analog that inhibits viral DNA synthesis.
It is effective against herpes simplex virus (HSV) and varicella zoster virus (VZV), but not against influenza virus.
Choice C is wrong because Efavirenz is wrong because it is a **non-nucleoside reverse transcript
