Instgra general information

What is Instgra used for?

Instgra tablets 50mg are used to treat Human Immunodeficiency Virus (HIV) infection, in combination with other HIV medications, in adults and children over 12 years of age and weighing 40 kg or more.  HIV impairs the immune system by attacking specific immune cells called CD4+ cells, a type of white blood cell involved in fighting infection, which can lead to opportunistic life-threatening infection (infections that would not normally be harmful).  If too many CD4+ cells are destroyed this can result in acquired immune deficiency syndrome (AIDS).  Instgra tablets 50mg help prevent or slow down the ability of HIV to replicate, which reduces the viral load by keeping the amount virus down to a low level and this results in an increase in CD4 cell numbers, so that the immune system can recover reducing the risk of disease progression. 

How does Instgra work?

Instgra tablets 50mg contains the antiretroviral dolutegravir, a second generation integrase strand transfer inhibitor.  Dolutegravir in Instgra tablets 50mg inhibits the catalytic activity of the enzyme HIV-1 integrase, an HIV-encoded enzyme that is essential for viral replication.  HIV is a retrovirus, which is an RNA virus that produces an enzyme called reverse transcriptase to transcribe its RNA into DNA.  Another viral enzyme, HIV-integrase, is used to insert or integrate viral DNA into the host cell genome during the early phase of infection.  Once integrated into the host cell DNA the viral DNA is replicated, transcribed into RNA and translated into viral proteins, the process known as gene expression, so that the viral proteins needed to make to virus particles are produced alongside host cell proteins. By blocking the action of viral integrase, dolutegravir in Instgra tablets 50mg prevents replication of the virus and thereby inhibits production of new infectious viral particles.  Instgra tablets 50mg 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.   

What does Instgra contain?

Instgra tablets 50mg contain the active ingredient antiretroviral dolutegravir, an antiretroviral used to treat HIV infection.

Treating HIV infection with Instgra

Instgra tablets 50mg contain the antiretroviral drug dolutegravir, an inhibitor of the viral integrase enzyme.  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), including pneumonia, herpes virus infections, and Mycobacterium avium complex (MAC) infection.  If too many CD4+ cells are destroyed this can result in acquired immune deficiency syndrome (AIDS).  HIV is a retrovirus, which is an RNA virus that produces an enzyme called reverse transcriptase to transcribe its RNA into DNA.  Another viral enzyme, integrase, is used to insert or integrate viral DNA into the host cell genome during the early phase of infection.  Dolutegravir in Instgra tablets 400mg works by blocking the action of the viral integrase and this inhibits viral replication and thereby inhibits production of new infectious viral particles.  Instgra tablets 50mg are used in combination with other HIV medications to slow down the replication of HIV within your body but they do not kill the virus already incorporated in the CD4+ cells or prevent the spread of the infection to others.
