About Acivir 400 mg
Acivir is an antiviral medicine used to treat viral infections.
Acyclovir, its active salt, is an effective remedy to treat symptoms involved in viral infections and ailments.

Acivir 400 mg Uses
Acivir 400 mg treats viral infections caused by specific virus types.
Its primary salt, Acyclovir, treats and regulates viral infections (such as Influenza, HIV, and Pneumonia).

Working of Acivir 400 mg
Acivir 400 contains Acyclovir as its primary salt.
It blocks viral DNA polymerase by acting like deoxyGuanosine Triphosphate (dGTP).
When Acyclovir is added to DNA, the chain ends, making it impossible for more nucleosides to join.
It sticks to viral DNA polymerase much better than it sticks to the cellular homolog, giving it a high therapeutic ratio.
Therefore, it effectively alleviates the symptoms of viral infections.
