Aloe Vera and HIV/AIDS: Separating Fact from Fiction

Introduction:

In recent years, there has been increasing interest in alternative and complementary therapies for various health conditions, including HIV/AIDS. One such natural remedy that has garnered attention is aloe vera. Aloe vera, a succulent plant known for its therapeutic properties, has been used for centuries in traditional medicine. However, when it comes to HIV, it is essential to separate fact from fiction and evaluate the scientific evidence available. In this blog post, we will delve into the topic of aloe vera and HIV, exploring its potential benefits, limitations, and the importance of evidence-based approaches.

Scientific Name: Aloe vera English Name: Aloe vera Hindi Name: घृतकुमारी (Ghritkumari) Marathi Name: कोरफड (Korphad)

Exploring Aloe Vera's Properties: Aloe vera is a versatile plant that contains various biologically active compounds, including vitamins, minerals, enzymes, amino acids, and polysaccharides. These components contribute to its anti-inflammatory, antioxidant, and immunomodulatory properties, which have made aloe vera a popular ingredient in skincare and wellness products.

Aloe Vera and Immune Health: One of the primary claims associated with aloe vera and HIV is its potential to boost immune function. While a healthy immune system is crucial in managing HIV infection, it is important to note that aloe vera alone cannot cure or treat the virus. HIV/AIDS management requires a comprehensive approach involving antiretroviral therapy (ART) and appropriate medical care.

Scientific Evidence: When it comes to aloe vera's impact on HIV, there is a significant lack of clinical studies and scientific evidence supporting its direct effectiveness in treating or managing the virus. While some studies have shown promising results in laboratory settings, it is important to recognize the limitations of in vitro studies and the need for further research. Currently, there is no conclusive evidence to support the use of aloe vera as a standalone treatment for HIV/AIDS.

Importance of Evidence-Based Approaches: Living with HIV/AIDS requires a well-informed approach based on evidence and guidance from healthcare professionals. It is crucial to prioritize proven medical interventions, such as antiretroviral therapy, which have been extensively studied and demonstrated to effectively manage HIV infection. Alternative therapies, including aloe vera, should be approached with caution and discussed with healthcare providers to ensure they do not interfere with standard treatment protocols.

Potential Considerations and Precautions: While aloe vera is generally considered safe for topical use, there are some important considerations and precautions to keep in mind. Ingesting aloe vera orally may have laxative effects and can interact with certain medications. Additionally, the quality and purity of aloe vera products can vary, making it essential to choose reputable sources and consult healthcare professionals before use.

Conclusion: While aloe vera possesses interesting properties and has been used in traditional medicine for various purposes, the evidence supporting its effectiveness in managing HIV/AIDS is currently lacking. It is crucial to rely on scientifically proven interventions, such as antiretroviral therapy, while approaching alternative therapies like aloe vera with caution. Prioritizing evidence-based approaches and consulting healthcare professionals are vital for individuals living with HIV/AIDS to ensure the most effective and safe management of their condition.

WHAT IS A-ZAM TREATMENT FOR HIV ?

Treatment of HIV Infection with a Herbal Mixture, A-ZAM, Among Clients seeking (discovering) Herbal Remedy in Nigeria (country in west Africa).

A-ZAM :

• Nigeria is the third country in the world with largest population of people infected with HIV infection.
• The use of herbal remedies for terminal illness is very common and the fact that HIV infection had no cure prompted many to seek for traditional medicines and spiritual solutions.
•  Α- Zam is an herbal remedy used for HIV infection in Nigeria.
• α-Zam is a mixture of many herbal materials and is used as alternative therapy to Highly Active Anti-retroviral Therapy (HAART).
• The study was to determine the effectiveness (CD4 count and viral load) of a safe herbal concoction, α-Zam used by clients seeking herbal remedy for treatment of HIV infection in Nigeria.
• A -ZAM is an herbal remedy that has been in use as alternative therapy  for HIV  infection in  Nigeria for about a decade( 10 year duration).
• This study focussed on safety of the α- Zam using animal models.
• This study was to determine the effectiveness (CD4 count and viral load) of a safe herbal mixture, α-Zam used by clients seeking herbal remedy for treatment of HIV infection in Nigeria.
• Since the discovery of acquired immunodeficiency syndrome (AIDS) linked with HIV as the causative agent in early 1980s, Nigeria was not excluded from the scourge of this dreadful infection.
• The use of herbal remedies for terminal illness is very common and the fact that HIV infection had no cure prompted many to seek for traditional medicines and spiritual solutions.
• Thus Nigerians living with HIV infection since 1987 when the first case was reported in the country resulted to super-natural solutions.
• Despite the widely availability of non-expensive Highly Active Antiretroviral therapy (HAART), many HIV patients in Nigeria are desperately looking for quicker solution to the existing problems of long duration therapy by patronising herbal .
• Regular visits were paid to the patients after commencement of the α-Zam to assess the side-effects, drug interactions, toxicity and effectiveness of the herbal remedy.
• There was a statistical significance (P<0.05) between pre-treatment and post-treatment CD4 count.
• 4 (7.8%) of the patients had average increase in CD4 count of 262±16 cell/µL, 23 (45.1%) patients with average increase 310±16 cell/µL, 16 (31.4%) patients with average increase 456±25 cell/µL and 8 (15.7%) patients with average increase 510±36 cell/µL( %) were at WHO staging I , II, III and IV respectively within 4 months on herbal therapy.
• There was very marked reduction in viral (HIV-RNA) load with 41 (80.4%) and10 (19.6%) HIV infected patients had undetectable viral load and <1000 copies/ml respectively after the therapy.
• All symptoms and signs associated with HIV infection in all patients fully subsided within 4 weeks of commencement of α-zam therapy and there was no evidence of negative drug interaction in those HIV patients using both the herbal and highly active anti-retroviral therapy (HAART).
• The effectiveness of herbal remedies in HIV infection is not doubtful. There are many herbal remedies that have been found to inhibit one or more steps in HIV replication.
• Alkaloids derivatives herbal remedies (e.g. Ancistrocladus korupensis) from tropical liana plant inhibit reverse transcriptase and HIV induced cell fusion.
• Pentosan poly-sulphate, a carbohydrate derivate inhibits HIV tat regulatory protein (p14) that strongly activates transcription of proviral DNA.
• A coumarin herbal remedy in form of canolides from tropical forest tree (Calophyllum lanigerum) was rated as non nucleoside reverse transcriptase inhibitor in potency.
• Despite the fact that sero-deconversion is very rare with HAART, some herbal remedies (e.g. Chinese medicines) have been documented in serodeconversion of HIV infected patients .
• However, many HIV patients taking herbal remedies denied when asked by medical practitioners.
• The possible negative drug interaction between orthodox medicine and herb had been a major concern.
• Herbal derived vitamins and garlic were documented to have caused negative drug interaction with anti-HIV drugs in some HIV patients.
• However, many herbal medicines decreased drug resistance associated orthodox anti-retroviral drugs. Coumarins in combination therapy with nevirapine (component of HAART) decreased resistance due to HIV mutation.
• There are many herbal remedies that are effective against HIV infection in Nigeria.
• Many of these documented herbal remedies act on the opportunistic infections caused by micro-organisms.
• Baissea axillaries Hua, a popular herbal remedy in Nigeria used to treat many diseases was also effective in bacterial caused opportunistic infections in HIV patients
• However, neem leaves that are widely distributed in Nigeria increased the CD4 count and general well being significantly in HIV patients.
• Thus there is a need to investigate the level of effectiveness of α-Zam, an herbal remedy used by many HIV patients in Nigeria in patients taking it as alternative or complementary therapy.
  
  
• Materials and Methods for A-ZAM
  
  
• Is a safe herbal concoction that contained saponins (titerpene glycosides), tannins, cardenolides, alkaloids and possibly anthraquinones.

The patients taking HAART with α-Zam as complementary therapy were noted.
  
  

             Furore over black seed, honey cure for HIV

   

• Mixture made predominantly with black seed (Nigella sativa) and honey provide the much sought after cure for the Human Immuno-deficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS)?
• Study by researchers from the University of Ibadan (UI)/University College Hospital (UCH), published in Journal of Herbal Medicine concluded: “This study concluded that the herbal remedy (α-Zam/Nigella Sativa and honey) is effective in the treatment of HIV infection based on a significant improvement in both the clinical features and laboratory results of HIV infection. However, a longer follow-up is suggested to ensure that the observed improvement is sustained. In addition, a large population study is needed to confirm our observation in this cohort of people.”
• According to the study, six patients taking this herbal concoction as an alternative therapy for HIV infection were recruited into the study and monitored for four months. All six patients were infected by HIV, as confirmed by Western blot analysis in the nearest teaching hospital, that is Ladoke Akintola University of Technology (LAUTECH) teaching hospital or Ahmadu Bello University Teaching Hospital, before commencing preliminary clinical and laboratory examinations using World Health Organization (WHO) and Centres for Disease Control and Prevention (CDC) criteria.
• The researchers noted: “The patients were contacted daily and visited regularly after commencement of herbal medications to assess the efficacy (disappearance of presenting signs and symptoms associated with HIV infection), side-effects, drug toxicity, and compliance. The symptoms and signs associated with HIV infection disappeared within 20 days of commencement of herbal therapy with significant difference (p < 0.05) before treatment and at periodic intervals on α-Zam therapy. Body weight increased from an average of 53 ± 2 kg to 63 ± 2 kg, viral load (HIV-RNA) decreased from 42,300 ± 1500 copies/ml to an undetectable level (≤50 copies/ml), and CD4+ count (a marker for the immune system) increased from an average of 227 ± 9 to 680 ± 12 mm3/μL at four months post-therapy. This study concluded that the herbal remedy (α-Zam) is effective in the treatment of HIV infection based on a significant improvement in both the clinical features and laboratory results of HIV infection. However, a longer follow-up is suggested to ensure that the observed improvement is sustained. In addition, a large population study is needed to confirm our observation in this cohort of people.”

Natural treatment for HIV/AIDS

NATURAL TREATMENT FOR HIV/AIDS

HIV/AIDS virus attack on host cell which is CD4 cell.In this article we see natural ways to increase CD4 count in our body.

Natural way to increase CD4 count

• The CD4 count is like a snapshot of how well your immune system is functioning. CD4 cells (also known as CD4+ T cells) are white blood cells that fight infection. The more you have, the better. These are the cells that HIV kills. As HIV infection progresses, the number of these cells declines. When the CD4 count drops below 200 due to advanced HIV disease, a person is diagnosed with AIDS. A normal range for CD4 cells is between 600 and 1,500.
  
  
• Here we see some natural way to increase cd4 count
  
  
• Zink
• 
  
  
  
  
  
  
• Zink is the most important component of an enzyme of cd4  cell. This mineral deficiency starts to reduce the number of white cells in the body. So, incorporate zinc into your diet. Zinc is useful for meat, fish and milk intake. Crab, scallops and red meats also have a very good zinc.

• Vitamin c
• 
  
  
• Vitamin C controls the cholesterol in the blood. Vitamin C helps to work properly on the cd4 cell and increases their number, making the immune system even stronger and helping to fight any kind of infection. Vitamin C is abundant in fruits, green vegetables, tomatoes, capsicum, juicy and sour fruits.
• Green tea
• 
  
  
• Green tea has the most amount of anti-oxidant and also does not have a calorie bill total. Green T also contains anti-oxidant other than vitamin C and poliphinal which strengthens the immune system by eliminating bacteria in the body and also whites a fighting cell.
• Garlic

  
• Garlic has a considerable antioxidant, which gives our immune system the strength to fight diseases. It also contains an element called Elisin that helps the body infection and fight bacteria. Using garlic in everyday food prevents stomach ulcers and cancer and also increases the number of white cell. The study of the 2002 found that whiteing the penis promotes the ability to fight cell infections, and also stimulates other immune cells.
• Yogurt
• 
  
  
• Everyday intake of yogurt the ability to fight the body's ailments and the increase number of cd4 cells. Yogurt has a high amount of calcium compared to milk. The bacteria and nutrients present in yogurt work as an antibiotic for the body, and also provide the ability to fight diseases.
• Folic acid
• 
  
  
• Folic acid is required to make the body a white cell. and folic acid deficiency can also reduce the level of red blood cells with anemia. Increasing the amount of folic acid can help you. So incorporate spinach, beans, and citrus fruits into your diet.

HIV/AIDS

HIV

 What is HIV ?

HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome, or AIDS, if not treated. Unlike some other viruses, the human body can’t get rid of HIV completely, even with treatment. So once you get HIV, you have it for life.

HIV is a virus that attacks cells in the immune system, which is our body’s natural defence against illness. The virus destroys a type of white blood cell in the immune system called a T-helper cell, and makes copies of itself inside these cells. T-helper cells are also referred to as CD4 cells.

HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get other infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last stage of HIV infection.

No effective cure currently exists, but with proper medical care, HIV can be controlled. The medicine used to treat HIV is called antiretroviral therapy or ART. If taken the right way, every day, this medicine can dramatically prolong the lives of many people infected with HIV, keep them healthy, and greatly lower their chance of infecting others.

  Stages of HIV Life Cycle or Steps of HIV Replication

1. Binding or Attachment stage
2. Fusion stage
3. Reverse transcription
4. Replication
5. Integration 
6. Assembly
7. Budding

Binding stage of HIV Life Cycle

In the binding or attachment stage of HIV Life cycle, the HIV virus attaches itself to the surface of CD4 cells by using its receptor known as gp120 (a glycoprotein) to attach to some receptors on the CD4 cells such as CCR5 receptors and CXCR4. The HIV virus only infects CD4 cells because these cells express the receptors that help the HIV virus to enter the cells. It is due to this infection that the HIV brings down the immune system of the body because the CD4 cells maintain the immunity of the body. This stage of HIV replication is inhibited by CCR5 drugs used for treatment of HIV infection.

Fusion stage of HIV Replication Cycle

After binding to the CD4 cell, the HIV virus then fuses its envelope (which serves as the covering of the virus) with the cell membrane of the CD4 cell. This enables the Virus to gain entry into the CD4 cell. This stage of HIV Replication is blocked by Fusion inhibitorswhich are drugs used for treatment of HIV infection.

Reverse transcription stage of HIV Replication

For a HIV virus to replicate, it must change from RNA (RiboNucleic Acid) to DNA (DeoxyriboNucleic Acid); for HIV to effect this change, it uses a protein (enzyme) called Reverse Transcriptase. This enzyme then changes the HIV RNA to HIV DNA. Once the HIV DNA is produced, it can then enter the Nucleus of the CD4 cell now (remember that it fused with the CD4 membrane to enter the cytoplasm; in the cytoplasm is another compartment (or organelle) called the nucleus where the genetic materials are stored to enable reproduction and transfer of genes for animals to give birth to their kind). This stage is blocked by two classes of HIV drugs:Nucleoside Reverse Transcriptase Inhibitors and Non-Nucleoside Reverse Transcriptase Inhibitors.

Integration stage of HIV Replication Cycle

Inside the CD4 nucleus, HIV then uses an enzyme known as Integrase to integrate (or insert) its vital DNA into the DNA of the CD4 cell. This stage is blocked using Integrase Inhibitors drugs.

Replication stage of HIV life Cycle

In the Nucleus of the CD4 cell, the HIV DNA combines with the CD4 DNA so that anytime the CD4 cell wants to produce, it uses the cells proteins to produce more HIV long chains Proteins thereby multiplying the HIV protein copies. This stage of HIV Life Cycle is called Replication and not Reproduction as in animals. There is currently no drug that blocks this stage.

Assembly stage of HIV Life Cycle

Once the HIV long chains proteins are produced, they move out of the Nucleus to the surface of the CD4 membrane to assemble into immature noninfectious HIV.

Budding stage of HIV Life Cycle

After moving to the surface of the CD4 membrane, the HIV releases another enzyme called Protease that helps to cleave or break up the long chains of HIV proteins into short chains of proteins. These short chains of HIV proteins then combine to form the Mature HIV virus that is infectious and can then infect another new CD4 cell. By this repeated replication and infection, it reduces the CD4 cells count in the body and the immunity of the HIV patient goes down. Protease Inhibitors are the HIV Drugs that block this stage.

HIV to AIDS

This is the stage of HIV infection that occurs when your immune system is badly damaged and you become vulnerable to opportunistic infections. When the number of your CD4 cells falls below 200 cells per cubic millimeter of blood (200 cells/mm3), you are considered to have progressed to AIDS. (In someone with a healthy immune system, CD4 counts are between 500 and 1,600 cells/mm3.) You are also considered to have progressed to AIDS if you develop one or more opportunistic illnesses, regardless of your CD4 count.

Without treatment, people who progress to AIDS typically survive about 3 years. Once you have a dangerous opportunistic illness, life-expectancy without treatment falls to about 1 year. ART can be helpful for people who have AIDS when diagnosed and can be lifesaving. Treatment is likely to benefit people with HIV no matter when it is started, but people who start ART soon after they get HIV experience more benefits from treatment than do people who start treatment after they have developed AIDS.

People living with HIV may progress through these stages at different rates, depending on a variety of factors, including their genetic makeup, how healthy they were before they were infected, how much virus they were exposed to and its genetic characteristics, how soon after infection they are diagnosed and linked to care and treatment, whether they see their healthcare provider regularly and take their HIV medications as directed, and different health-related choices they make, such as decisions to eat a healthful diet, exercise, and not smoke.

Sign and symptoms

The symptoms of HIV at each stage can vary in type and severity from person-to-person and some people may not get any symptoms at all for many years. Without antiretroviral treatment, the virus replicates in the body and causes more and more damage to the immune system. This is why people need to start treatment as soon as possible after testing positive.

Stage 1: Acute primary infection

Around one to four weeks after getting HIV, some people will experience symptoms that can feel like flu. These may not last long (a week or two) and you may only get some of the flu symptoms – or none at all. Experiencing these symptoms alone is not a reliable way of diagnosing HIV.

You should always visit your healthcare professional if you’re worried about or think you’ve been at risk of getting HIV, even if you don’t feel unwell or have any of the following symptoms. They can then arrange for you to get tested.

Symptoms can include:

• fever (raised temperature)
• body rash
• sore throat
• swollen glands
• headache
• upset stomach
• joint aches and pains
• muscle pain.

These symptoms can happen because your body is reacting to the HIV virus. Cells that are infected with HIV are circulating throughout your blood system. Your immune system, in response, tries to attack the virus by producing HIV antibodies - this process is called seroconversion. Timing varies but once you have HIV it can take your body up to a few months to go through the seroconversion process.

It may be too early to get an accurate HIV test result at this point ,but the levels of virus in your blood system are high at this stage.

Because you may not know that you (or your partner) have HIV, condoms are the best way to protect yourself and your partner when having sex. Using a condom is especially important if you think you have been exposed to HIV.

Stage 2: The asymptomatic stage

Once a person has been through the acute primary infection stage and seroconversion process, they can often start to feel better. In fact, HIV may not cause any other symptoms for up to 10 or even 15 years (depending on age, background and general health). However, the virus will still be active, infecting new cells and making copies of itself. If left untreated, over time, this will cause severe damage to the immune system.

Stage 3: Symptomatic HIV infection

By the third stage of HIV infection a person’s immune system is severely damaged. At this point, they’re more likely to get serious infections, or bacterial and fungal diseases that the body would otherwise be able to fight off. Symptoms can include:

• weight loss
• chronic diarrhoea
• night sweats
• fever
• persistent cough
• mouth and skin problems
• regular infections
• serious illness or disease.
•  

• Treatment

• Antiretroviral Therapy
  
  
• HIV medications can help lower your viral load, fight infections, and improve your quality of life. But even if you take them, you can still give HIV to others. They're not a cure for HIV.
• The goals for these medicines are to:
• Control the growth of the virus
• Improve how well your immune system works
• Slow or stop symptoms
• Prevent transmission of HIV to others
• The FDA has approved more than two dozen antiretroviral drugs to treat HIV infection. They're often broken into six groups because they work in different ways. Doctors recommend taking a combination or "cocktail" of at least two of them. This is called antiretroviral therapy, or ART.
• Your doctor will let you know specifically how you should take your medications. You need to follow the directions exactly, and you shouldn't miss even one dose. If you miss doses, you could develop drug-resistant strains of HIV, and your medication may stop working.
  
  
• Classes of drugs
  
  
• Schematic description of the mechanism of the four classes of currently available antiretroviral drugs against HIV
• There are six classes of drugs, which are usually used in combination, to treat HIV infection. Antiretroviral (ARV) drugs are broadly classified by the phase of the retrovirus life-cycle that the drug inhibits. Typical combinations include 2 Nucleoside reverse transcriptase inhibitors (NRTI) as a "backbone" along with 1 Non-Nucleoside reverse transcriptase inhibitor (NNRTI), protease inhibitor (PI) or Integrase inhibitors (also known as integrase nuclear strand transfer inhibitors or INSTIs) as a "base."
• 
  
• Entry inhibitors
• Entry inhibitors (or fusion inhibitors) interfere with binding, fusion and entry of HIV-1 to the host cell by blocking one of several targets. Maraviroc and enfuvirtide are the two currently available agents in this class. Maraviroc works by targeting CCR5, a co-receptor located on human helper T-cells. Caution should be used when administering this drug however due to a possible shift in tropism which allows HIV to target an alternative co-receptor such as CXCR4. In rare cases, individuals may have a mutation in the CCR5 delta gene which results in a nonfunctional CCR5 co-receptor and in turn, a means of resistance or slow progression of the disease. However, as mentioned previously, this can be overcome if an HIV variant that targets CXCR4 becomes dominant. To prevent fusion of the virus with the host membrane, enfuvirtide can be used. Enfuvirtide is a peptide drug that must be injected and acts by interacting with the N-terminal heptad repeat of gp41 of HIV to form an inactive hetero six-helix bundle, therefore preventing infection of host cells.
  
  
• Nucleoside/nucleotide reverse transcriptase inhibitors
• Nucleoside reverse transcriptase inhibitors (NRTI) and nucleotide reverse transcriptase inhibitors (NtRTI) are nucleoside and nucleotide analogues which inhibit reverse transcription. HIV is an RNA virus and hence unable to become integrated into the DNA in the nucleus of the human cell; it must be "reverse" transcribed into DNA. Since the conversion of RNA to DNA is not done in the mammalian cell it is performed by a viral protein which makes it a selective target for inhibition. NRTIs are chain terminators such that once incorporated, work by preventing other nucleosides from also being incorporated into the DNA chain because of the absence of a 3' OH group. Both act as competitive substrate inhibitors. Examples of currently used NRTIs include zidovudine, abacavir, lamivudine, emtricitabine, and tenofovir.
• Non-nucleoside reverse transcriptase inhibitors
• Non-nucleoside reverse transcriptase inhibitors (NNRTI) inhibit reverse transcriptase by binding to an allosteric site of the enzyme; NNRTIs act as non-competitive inhibitors of reverse transcriptase. NNRTIs affect the handling of substrate (nucleotides) by reverse transcriptase by binding near the active site. NNRTIs can be further classified into 1st generation and 2nd generation NNRTIs. 1st generation NNRTIs include nevirapine and efavirenz. 2nd generation NNRTIs are etravirine and rilpivirine. HIV-2 is naturally resistant to NNRTIs.
  
  
• Integrase inhibitors
•  Integrase inhibitors (also known as integrase nuclear strand transfer inhibitors or INSTIs) inhibit the viral enzyme integrase, which is responsible for integration of viral DNA into the DNA of the infected cell. There are several integrase inhibitors currently under clinical trial, and raltegravir became the first to receive FDA approval in October 2007. Raltegravir has two metal binding groups that compete for substrate with two Mg2+ ions at the metal binding site of integrase. As of early 2014, two other clinically approved integrase inhibitors are elvitegravir and dolutegravir.
  
  
• Protease inhibitors
• Protease inhibitors block the viral protease enzyme necessary to produce mature virions upon budding from the host membrane. Particularly, these drugs prevent the cleavage of gag and gag/pol precursor proteins. Virus particles produced in the presence of protease inhibitors are defective and mostly non-infectious. Examples of HIV protease inhibitors are lopinavir, indinavir, nelfinavir, amprenavir and ritonavir. Darunavir and atazanavir are currently recommended as first line therapy choices. Maturation inhibitors have a similar effect by binding to gag, but development of two experimental drugs in this class, bevirimat and vivecon, was halted in 2010.Resistance to some protease inhibitors is high. Second generation drugs have been developed that are effective against otherwise resistant HIV variants.
  
  
• Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs)
• NRTIs force the HIV virus to use faulty versions of building blocks so infected cells can't make more HIV.
• Abacavir, or ABC (Ziagen)
• Didanosine, or ddl (Videx)
• Emtricitabine, or FTC (Emtriva)  
• Lamivudine, or 3TC (Epivir)
• Stavudine, or d4T (Zerit)
• Tenofovir, or TDF (Viread), or TAF (Vemlidy)
• Zidovudine, or AZT or ZDV (Retrovir)
• Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs)
• These are also called "non-nukes." NNRTIs bind to a specific protein so the HIV virus can't make copies of itself, similar to jamming a zipper.
• Delavirdine, or DLV  (Rescriptor)
• Efavirenz, or EFV (Sustiva)
• Etravirine, or ETR (Intelence)
• Nevirapine, or NVP (Viramune)
• Rilpivirine, or RPV (Edurant)
• Protease Inhibitors (PIs)
• These drugs block a protein that infected cells need to put together new HIV virus particles.
• Amprenavir (Agenerase)
• Atazanavir, or ATV (Reyataz)
• Darunavir, or DRV (Prezista)
• Fosamprenavir, or FPV (Lexiva)
• Indinavir, or IDV (Crixivan)
• Lopinavir + ritonavir, or LPV/r (Kaletra)
• Nelfinavir, or NFV (Viracept)
• Ritonavir, or RTV (Norvir)
• Saquinavir, or SQV (Invirase, Fortovase)
• Tipranavir, or TPV (Aptivus)
• Fusion Inhibitors
• Unlike NRTIs, NNRTIs, and PIs -- which work on infected cells -- these drugs help block HIV from getting inside healthy cells in the first place.
• Enfuvirtide, or ENF or T-20 (Fuzeon)
• CCR5 Antagonist
• Maraviroc, or MVC (Selzentry), also stops HIV before it gets inside a healthy cell, but in a different way than fusion inhibitors. It blocks a specific kind of "hook" on the outside of certain cells so the virus can't plug in.
• Integrase Inhibitors
• These stop HIV from making copies of itself by blocking a key protein that allows the virus to put its DNA into the healthy cell's DNA. They're also called integrase strand transfer inhibitors (INSTIs).
• Bictegravir, or BIC (combined with other drugs as Biktarvy)
• Dolutegravir, or DTG (Tivicay)
• Elvitegravir, or EVG (Vitekta)
• Raltegravir, or RAL (Isentress)
• Monoclonal Antibody
• This is a new class of antiviral medication specifically for adults living with HIV who have tried multiple HIV medications and whose HIV has been resistant to current available therapies. Ibalizumab-uiyk (Trogarzo) blocks your body’s HIV infected cells from spreading the virus into those which are uninfected. It is administered by IV.
• Cobicistat (Tybost) is a drug that helps some drugs (atazanavir, darunavir, elvitegravir) work better, but it can increase the levels of other medicines you may be taking (always tell your doctor about these other medicines).
• Atazanavir + cobicistat, or ATV/c (Evotaz)
• Darunavir + cobicistat, or DRV/c (Prezcobix)
• Elvitegravir + TDF + FTC + cobicistat, or EVG/c/TDF/FTC (Stribild)
• Elvitegravir + TAF + FTC + cobicistat, or EVG/c/TAF/FTC  (Genvoya)
• Fixed-Dose Combinations
• Some drug manufacturers put together specific medicines into a single pill so they're easier to take, including:
• Abacavir + dolutegravir + lamivudine, or ABC/DTG/3TC (Triumeq)
• Abacavir + lamivudine, or ABC/3TC (Epzicom)
• Abacavir + lamivudine + zidovudine, or ABC/3TC/ZDV (Trizivir)
• Atazanavir + cobicistat, or ATV/c (Evotaz)
• Atazanavir + cobicistat, or ATV/c (Evotaz)
• Bictegravir +   emtricitabine + tenofovir alafenamide, or BIC/FTC/TAF (Biktarvy)
• Dolutegravir + rilpivirine, or DTG/RPV (Juluca)
• Durunavir + cobicistat, or DRV/c (Prezcobix)
• Efavirenz + emtricitabine + tenofovir, or EFV/FTC/TDF (Atripla)
• Elvitegravir + cobicistat + emtricitabine + tenofovir, or EVG/c/FTC/TAF  (Genvoya)
• Elvitegravir + cobicistat + emtricitabine + tenofovir, or EVG/COBI/FTC/TDF or ECF/TDF (Stribild)
• Emtricitabine + rilpivirine + tenofovir, or FTC/RPV/TAF (Odefsey)
• Emtricitabine + rilpivirine + tenofovir, or FTC/RPV/TDF (Complera)
