nucleoside reverse transcriptase inhibitor
Definition
- Noun:
- A class of antiretroviral medication: A nucleoside reverse transcriptase inhibitor (NRTI) is a type of antiviral drug specifically used in the treatment of HIV infection. It works by inhibiting the action of the reverse transcriptase enzyme, which is crucial for the virus to replicate its genetic material.
Usage
- NRTIs are a foundational component of most HIV treatment regimens.
- They are almost always used in combination with other classes of antiretroviral drugs to form a complete treatment strategy, known as combination therapy.
- This term is primarily used in medical, pharmacological, and public health contexts.
Examples
- Noun:
- The doctor prescribed a regimen containing a nucleoside reverse transcriptase inhibitor.
- Tenofovir and lamivudine are examples of nucleoside reverse transcriptase inhibitors.
Advanced Usage
- "NRTI": This is the standard and widely used acronym for "nucleoside reverse transcriptase inhibitor."
- The patient's new regimen includes two NRTIs and an integrase inhibitor.
Variants and Related Words
- Non-nucleoside reverse transcriptase inhibitor (NNRTI) (n): A different class of antiretroviral drug that also targets the reverse transcriptase enzyme but through a different mechanism of action.
- Efavirenz is a non-nucleoside reverse transcriptase inhibitor.
Synonyms
- NRTI (n): The direct acronym.
- Nucleoside analogue (n): A broader term describing the chemical structure; many NRTIs are nucleoside analogues.
Related Terms
- Reverse transcriptase (n): The viral enzyme that is the target of this drug class.
- Antiretroviral therapy (ART) (n): The overall treatment for HIV that includes NRTIs and other drugs.
- Combination therapy (n): The standard HIV treatment approach using multiple drugs from different classes, which almost always includes an NRTI.
Noun
-
an antiviral drug used against HIV; is incorporated into the DNA of the virus and stops the building process; results in incomplete DNA that cannot create a new virus; often used in combination with other drugs
