First approved in 1987, the drug azidothymidine (AZT), now known as zidovudine, was the first medication to be made available for the treatment of HIV/AIDS, offering a glimmer of hope during a critical period of the epidemic. Its effectiveness hinges on its ability to inhibit a specific viral enzyme: HIV reverse transcriptase.

While the nucleoside reverse transcriptase inhibitor (NRTI) lamivudine has a significantly lower risk of causing peripheral neuropathy compared to older agents like stavudine, it can still occur as a side effect. This condition can manifest as numbness, tingling, or burning sensations, primarily in the hands and feet.

NRTIs, or nucleoside reverse transcriptase inhibitors, were the first class of antiretroviral drugs to be approved by the FDA for HIV treatment, marking a monumental step in managing the infection. Understanding what is the mechanism of action of NRTI is crucial for comprehending how these foundational drugs work to combat the virus at its core.

First approved by the FDA in 2003, emtricitabine (FTC) is a nucleoside reverse transcriptase inhibitor (NRTI). This classification places it among the essential antiretroviral drugs used in combination to treat and prevent HIV infection, leveraging its unique mechanism to block viral replication.

Emtricitabine is a cornerstone of modern antiretroviral therapy (ART) and HIV pre-exposure prophylaxis (PrEP), widely used in combination with other medications. So, what class of antiviral is emtricitabine? It belongs to the nucleoside reverse transcriptase inhibitor (NRTI) drug class.

Atripla, a discontinued fixed-dose combination therapy, contains three distinct antiretroviral medications that work together to prevent the human immunodeficiency virus (HIV) from replicating. Though the branded version is no longer produced, its generic equivalent remains a key option for controlling HIV infection in adults and children.

As of 2025, an estimated 28 million people globally are receiving antiretroviral therapy (ART) to manage HIV. Two cornerstone classes of these life-saving drugs are NRTIs and NNRTIs. Understanding **what is the difference between NRTI and Nnrti** is crucial to appreciating how modern combination therapies work to control the virus.

Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) that has been a cornerstone of HIV treatment and prevention for over two decades. Knowing what does emtricitabine target is key to understanding its efficacy in slowing the progression of Human Immunodeficiency Virus (HIV) and managing Hepatitis B Virus (HBV). By inhibiting a specific viral enzyme, the medication effectively prevents the virus from replicating and overwhelming the immune system.

As a critical component of antiretroviral therapy (ART) for HIV, abacavir is a well-established medication. To answer the question, "Which class is abacavir?", it belongs to the nucleoside reverse transcriptase inhibitor (NRTI) class.

Stavudine has long been recognized as a medication capable of causing pancreatitis, a serious and sometimes fatal inflammation of the pancreas. This risk is heightened when the drug is used in combination with other antiretroviral agents, particularly didanosine. While its use has declined in favor of safer alternatives, understanding this adverse effect is critical for patients, especially in resource-limited settings where the drug is still prevalent.
