overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Nucleoside Reverse Transcriptase Inhibitors (NRTIs) are a class of antiretroviral drugs used primarily in the treatment of HIV/AIDS. They work by mimicking natural nucleosides, thereby inhibiting the reverse transcriptase enzyme essential for the replication of HIV, which prevents the virus from multiplying within the host's body.
Key Features
- Mimic naturally occurring nucleosides to interfere with viral DNA synthesis
- Effective in suppressing HIV viral load when used as part of combination therapy
- Typically administered orally
- Can cause side effects such as lactic acidosis and mitochondrial toxicity
- Include drugs like zidovudine (AZT), lamivudine (3TC), and tenofovir
Pros
- Highly effective in reducing HIV viral load
- Help improve immune function and slow disease progression
- Well-studied with decades of clinical use
- Available in combination formulations for enhanced efficacy
Cons
- Potential for serious side effects, including mitochondrial toxicity
- Development of drug resistance if not taken consistently
- Requires lifelong adherence to therapy
- Possible interactions with other medications
