Efavir (Efavirenz 200mg Tablets)

Efavir (Efavirenz 200mg Tablets)

The main active ingredient is Efavir (Efavirenz 200mg Tablets), Non-nucleoside Reverse Transcriptase Inhibitors, used actively against HIV or AIDS virus. This medicine is quite effective to reduce the discomfort and severity of AIDS and it is a very popular part of antiretroviral therapy.

Efavir (Efavirenz 200mg Tablets) used for?

Efavir (Efavirenz 200mg Tablets) (also known as Sustiva) are used with other HIV medications as part of combination therapy for the treatment of Human Immunodeficiency Virus (HIV) infection in adults and children three years of age or older.  Efavir (Efavirenz 200mg Tablets) must not be used alone as the virus can develop resistance if used as monotherapy and Efavir (Efavirenz 200mg Tablets) is, therefore, combined with two other drugs that have a different mechanism of action.  This treatment regime is known as highly active antiretroviral therapy (HAART) and is designed to minimise the ability of the virus to multiply and help prevent development of viral resistance to treatment.  HIV impairs the immune system by attacking specific immune cells called CD4+ cells that are involved in fighting infection and this can lead to opportunistic life-threatening infection (infections that would not normally be harmful).  Also if too many CD4+ cells are destroyed this can result in acquired immune deficiency syndrome (AIDS).  Efavir (Efavirenz 200mg Tablets) slows down the ability of HIV to replicate and spread, which keeps the amount virus down to a low level (reduces viral load) and this results in an increase in CD4+ cell numbers, so that the immune system can recover, reducing the risk of disease progression. 

Efavir (Efavirenz 200mg Tablets) work?

Efavir (Efavirenz 200mg Tablets) (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 (Efavirenz 200mg Tablets) 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 (Efavirenz 200mg Tablets) 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.
