How has medication and treatments for HIV changed and improved over the years?
Treatment of HIV has evolved from gruelling regimens with high pill burden, inconvenient dosing, treatment-limiting toxicities, food and drug interactions, incomplete viral suppression and emergence of drug resistance to manageable one or two pill once daily regimens that can be initiated in early HIV disease and …
Treatment that uses a combination of three or more drugs to treat HIV infection. Highly active antiretroviral therapy stops the virus from making copies of itself in the body. This may lessen the damage to the immune system caused by HIV and may slow down the development of AIDS.
ARV drugs do not ‘kill’ HIV virus but prevents HIV virus from multiplying and destroying infection fighting CD4 (soldier of the body) cells. CD4 cell are an important part of the immune system because they fight germs and infection. This helps the body fight off life threatening infections and cancer.
When was HIV treatment effective?
In March 1987, AZT became the first drug to gain approval from the U.S. Food and Drug Administration for treating AIDS. AZT, also referred to as zidovudine, belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors, or NRTIs.
How does antiretroviral medication work?
Antiretroviral drugs HIV is treated with antiretroviral medicines, which work by stopping the virus replicating in the body. This allows the immune system to repair itself and prevent further damage. A combination of HIV drugs is used because HIV can quickly adapt and become resistant.
Highly active antiretroviral therapy (HAART) is a medication regimen used to manage and treat human immunodeficiency virus type 1 (HIV-1). It is composed of several drugs in the antiretroviral classes of medications.
In 1987 the US Food and Drug Administration approved the use of azidothymidine (AZT), the first antiretroviral drug for treatment of HIV/AIDS. AZT monotherapy slowed viral replication and disease progression but added only months to life and had severe side effects.
Summary: Antiretroviral therapy (ART) is usually effective at suppressing HIV, allowing the immune system to recover by preventing the virus from destroying CD4+ T cells. Scientists have now identified a rare, paradoxical response to ART called extreme immune decline, or EXID.
What is antiretroviral therapy (ART) for HIV?
Antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection is a treatment regimen used to reduce the amount of the virus in the body (viral load). There is no cure for HIV, but antiretroviral therapy can slow the progress of the infection and reduce the chances of transmission to others.
How does combination antiretroviral therapy work?
Combination antiretroviral therapy works by blocking several stages of the HIV life cycle. There are currently six classes of antiretroviral drugs, each classified by the stage of the cycle they inhibit:
Antiretroviral Drug Discovery and Development. For more than three decades, NIAID has fostered and promoted development of antiretroviral therapies that have transformed HIV infection from an almost uniformly fatal infection into a manageable chronic condition.
HIV variants with mutations that confer resistance to an antiretroviral drug can evolve rapidly. In some people taking AZT alone, drug resistance developed in a matter of days. Scientists thus tested whether combining drugs would make it difficult for the virus to become resistant to all the drugs simultaneously.
