Current Available Treatments for HIV

The main treatment for HIV is antiretroviral therapy, or ART, and is a combination treatment. This combination of daily medicines is known as an HIV treatment regimen. Antiretroviral therapy is used with anyone who presents with HIV. This therapy cannot totally cure the illness but does increase life expectancy in better health. It also lowers the chance of transmitting the disease to anyone else.

There are different drug classes used to treat HIV, normally a patient will start their treatment by taking 3 drugs from at least 2 different classes. There are also combination medicines across multiple classes, let’s take a look at the current treatments offered.


Nucleoside Reverse Transcriptase Inhibitors prevent an enzyme that is required by the virus to multiply. Listed using the generic names in the order of release.

■  Zidovudine

■  Lamivudine

■  Abacavir

■  Tenofovir disoproxil fumarate

■  Emtricitabine


Non-Nucleoside Reverse Transcriptase Inhibitors are also used to prevent the virus from multiplying. They work by binding to the enzyme responsible and altering it so that it can’t make copies.

■  Nevirapine

■  Efavirenz

■  Etravirine

■  Rilpivirine

■  Doravirine


Protease Inhibitors block the protease enzyme within HIV, also stopping multiplication.

■  Ritonavir

■  Atazanavir

■  Fosamprenavir

■  Tipranavir

■  Darunavir

Fusion Inhibitors

These fusion inhibitors block entry to the CD4 T lymphocyte, also known as CD4 cells, within the immune system.

■  Enfuvirtide

CCR5 Antagonists

CCR5 coreceptors are blocked by these antagonists. This happens on the surface of certain cells required by HIV to gain entry to these immune cells.

■  Maraviroc


Integrase Strand Transfer Inhibitors prevent the HIV integrase, an enzyme used by the virus to multiple.

■  Raltegravir

■  Dolutegravir

■  Cabotegravir

Attachment Inhibitors

These inhibitors bind themselves to a protein on the surface of HIV. The gp120 protein with the inhibitors attached cannot then enter the CD4 cells.

■  Fostemsavir

Post Attachment Inhibitors

CD4 receptors are blocked with Post Attachment Inhibitors. This prevents HIV from breaking through the surface of certain immune cells.

■  Ibalizumab-uiyk

Pharmacokinetic Enhancers

These drugs are used to increase how well other treatments in the regimen work.

■  Cobicistat

Combination HIV Treatments

Combining 2 or more meds from single or multiple classes into 1 medicine. There are many of these combining drugs we have previously mentioned sometimes allowing the patient to only need one pill per day.

What Will an HIV Regimen Include?

What medicines are chosen, will depend on the individual needs of the patient. The medical professionals will consider lots of different things that affect treatment. This will include possible interactions with other drugs taken, and the side effects caused could also make different meds preferable.

Often the side effects caused will not be too serious and can be managed by the patient. But some side effects can potentially be very serious. However, the benefit of HIV meds certainly outweighs the downsides.

As new treatments are developed, these side effects are often reduced. Even if side effects are an issue now, that may not always be the case.

When Should HIV Treatments Start Being Taken?

It is important to begin treatment soon after infection. This is even more important if the patient has opportunistic infections or cancer where they need to begin their HIV medicine regimen as soon as possible.
