How It Works (Mechanism of Action)
Zidovudine works by inhibiting the action of reverse transcriptase, an enzyme that HIV needs to multiply. This helps reduce the amount of virus in the body, allowing the immune system to function better.
Scientifically, Zidovudine is a nucleoside reverse transcriptase inhibitor (NRTI). It incorporates itself into the viral DNA chain and causes chain termination, preventing the virus from replicating effectively.
