According to medical experts, HIV/AIDS can be the cause of the most dreadful epidemic mankind has ever witnessed. Human immunodeficiency virus is a sexually transmitted infection that does not have any cure till date. All the available treatment options for this disease are capable of suppressing the symptoms. Best among these treatment options is the one that suppresses AIDS-related symptoms for as long as possible. As per the recommendations made by a panel of leading AIDS specialists, highly active retroviral therapy or HAART is one such treatment option.
The basic objective of HAART method is to improve the life expectancy of a HIV-infected person by reducing the amount of virus present in the blood to very low or almost undetectable levels. This objective is achieved by means of administrating more than 2 different kinds of anti-retroviral drugs as a combination therapy. These anti-retroviral drugs are medications used for the treatment of infections caused by retroviruses like HIV. There are six different classes of antiretroviral drugs available in the market whose function is to act as potent inhibitors at different stages of HIV lifecycle and prevent the growth, replication and proliferation of the virus.
Combination of antiretroviral drugs belonging to different classes helps in creating multiple obstacles for the virus at each stage of its lifecycle thus reducing the ability of the virus to replicate. This strategy has also been effective against drug-resistant strains of HIV. Drug-resistant strains arise as a result of mutations occurring in the viral genome. The most favored combination of antiretroviral drugs in a HAART method is the triple-cocktail approach where two nucleoside-analogue RTIs and one non-nucleoside-analogue RTI or a protease inhibitor are used.
