Common Adverse Effects of Antiretroviral Therapy for HIV Disease

arv drug classes

Currently, more than 30 antiretroviral drugs are available, including several fixed-dose combinations, which contain two or more medications from one or more drug classes in a single tablet. The search for new drugs remains a priority due to the development of resistance against existing drugs and the unwanted side effects associated with some current drugs. This drug can also cause lactic acidosis and severe liver and kidney problems. Fatty meal can improve absorption of some protease inhibitors like nelfinavir and lopinavir. The evidence is of low to moderate quality and therefore it is likely that future research may change these findings. Combination drugs combine medications from different classes into one drug form.

This is not an example of the work written by our professional academic writers. The choice of the specific first-line antiretroviral regimen depends on multiple factors, including medical comorbidities, potential drug interactions, and patient preferences pill burden, frequency of dosing, and requirements to take with or without food. Dual energy x-ray absorptiometry should be considered in patients older than 50 years. Even where such treatment is available, however, its use is complicated by a number of factors, including side effects, drug-drug interactions, and the selection of drug-resistant virus. J Acquir Immune Defic Syndr. Studies have shown that it is 5 to 10 times more potent than the other nucleosides. Antiretroviral drugs must be taken at the right time and in the right way for them to work properly.

Note that dolutegravir is also a component of two fixed-dose combinations: dolutegravir-abacavir-lamivudine and dolutegravir-rilpivirine. Rilpivirine also causes adverse central nervous system adverse effects in some patients, but to a lesser degree than efavirenz. Fusion inhibitors Fusion inhibitors are a group of drugs that block the entry of the virus into the cells of the affected individual host. Examples of drugs that may cause it: Combinations of drugs from the and protease inhibitor classes. For these drugs to be active they need to be phosphorylated intracellularly. The trimer of heterodimers is arranged arranged in a tripod-like conformation. Department of Health and Human Services; 2011.

Hypersensitivity reactions are also seen with enfuvirtide. To prevent fusion of the virus with the host membrane, enfuvirtide can be used. Raltegravir Isentress is the first medicine to be approved in the class of antiretroviral drugs called integrase inhibitors. Patients taking maraviroc also report more fever and esophageal candidiasis, but fewer headache symptoms than those receiving placebo. Lactic acidosis occurs more often in women and causes fatigue, belly pain, and shortness of breath.

By blocking the interactions between regions of the gp41 molecule, fusion inhibitors interfere with the conformational change folding of the envelope molecule required for fusion with the target cell membrane. Information from references , , and. The Gag polyprotein contains four structural proteins: matrix p17 , capsid p24 , nucleocapsid p7 , and p6 proteins. Treatment of Dyslipidemia in Patients with Human Immunodeficiency Virus Infection Lifestyle and dietary changes Medications Dietary cholesterol intake 200 kcal per day Saturated fat intake 200 to 499 mg per dL 2. Improved outcomes with earlier initiation of highly active antiretroviral therapy among human immunodeficiency virus-infected patients who achieve durable virologic suppression: longer follow-up of an observational cohort study. Viral particles are still produced when the protease is inhibited, but these particles are not effective at infecting new cells. A second combination pill, Trizivir, is also available.

Protease Inhibitors Protease is an enzyme responsible for cutting large protein molecules to produce the smaller structural proteins of the mature virus. These errors, or mutations, cause small changes in the virus. Patients should be screened for traditional cardiac risk factors e. Movement from the open to closed causes the flap ends to overlap and functionally act as a molecular scissors. Vitamin D levels should be monitored if clinically indicated. However, when people stop taking tesamorelin, belly fat is likely to come back. Tenofovir contains a single phosphonate group to which only two phosphate groups need to be added to generate the active compound.

Step 8 is the budding and maturation of new viral particles, which then go on to infect other host cells. Entry and fusion inhibitors block these receptors, preventing the virus from entering the cells. The use of the drug is also known to cause enlargement of lymph nodes and increased incidence of pneumonia. This three drug combination is commonly known as a triple cocktail.
