Sustiva Overview
Sustiva, also known by its generic name Efavirenz, is an antiviral medication used to treat HIV infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs).
- Drug Name: Sustiva (Efavirenz)
- Drug Class: Non-nucleoside reverse transcriptase inhibitor (NNRTI)
- Indication: Treatment of HIV infection
According to the World Health Organization (WHO), HIV remains a major global public health issue, with an estimated 38 million people living with the virus worldwide. Antiretroviral therapy (ART), including drugs like Sustiva, is essential for managing HIV and improving the quality of life for those affected.
Sustiva works by inhibiting the reverse transcriptase enzyme, which is crucial for the replication of the HIV virus. This mechanism of action helps reduce viral load and allows the immune system to function more effectively in controlling the infection.
It is important for individuals taking Sustiva to adhere to their prescribed treatment regimen to ensure optimal viral suppression and reduce the risk of developing drug-resistant strains of HIV.
Common side effects of Sustiva may include dizziness, drowsiness, and vivid dreams. It is essential to consult a healthcare provider before starting any antiretroviral treatment to discuss potential side effects and interactions with other medications.
For more information on Sustiva, its dosage, and precautions, refer to the WHO HIV/AIDS fact sheet and consult with a healthcare professional.

Use in Treating HIV infection
Studies have shown that Sustiva is highly effective in managing HIV infection by suppressing the viral replication process. Clinical trials have demonstrated that Sustiva, when used in combination with other antiretroviral drugs, can significantly reduce the viral load in patients with HIV. The medication works by inhibiting the reverse transcriptase enzyme, which is essential for the replication of the HIV virus.
Benefits of Sustiva in HIV Treatment:
- Effective in lowering viral load
- Reduces the risk of developing drug resistance
- Improves the overall immune system health
- Offers once-daily dosing convenience
Additionally, a survey conducted among HIV patients revealed that Sustiva has been well-tolerated with few reported side effects. Common side effects may include dizziness, vivid dreams, and rash. However, these side effects are usually mild and temporary.
Efficacy of Sustiva in Clinical Trials:
| Study | Results |
|---|---|
| ACTG 5095 trial | Sustiva-based regimens demonstrated superior virological outcomes compared to other regimens. |
| Atripla Study | Combination therapy with Sustiva showed sustained viral suppression and improved quality of life for HIV patients. |
In conclusion, Sustiva remains a cornerstone in the treatment of HIV infection due to its efficacy, tolerability, and convenience of dosing. Consulting a healthcare provider before starting Sustiva is crucial to ensure proper management and monitoring of HIV.
