4. Mechanism Action Of Efavir 200mg?

Efavir 200mg Capsule (also known as Sustiva) contain efavirenz, a non-nucleoside analogue reverse transcriptase inhibitor (NNRTI), which is only effective against RNA viruses (retroviruses) like Human Immunodeficiency Virus (HIV). 

It works by inhibiting the action of the viral-specific enzyme reverse transcriptase (RT), which is needed for the virus to be able to replicate.  Retroviruses convert RNA to DNA, which is then integrated into the DNA of infected immune cells so that the virus can replicate. 

Efavirenz in Efavir 200mg Capsule acts by binding to a specific site on the RT enzyme and blocks its action in a manner that is noncompetitive with nucleosides (precursors to the building blocks of DNA and RNA), thereby preventing the conversion of viral RNA to DNA. 

This action prevents the integration of virus into the DNA of the infected CD4+ immune cell, which inhibits the replication of HIV so that no more virus can be produced; and this reduces the viral load (amount of virus). 

Efavir 200mg Capsule slow down the replication of HIV within your body but does not kill the virus already incorporated in the CD4+ cells or prevent the spread of the infection to others.
