Overview of Sustiva – Uses, Names, and Classification as NNRTI

Overview of Sustiva and its Uses

Sustiva, also known as efavirenz, is an antiviral medication that is primarily used to treat HIV-1 infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs).

When a person is infected with HIV, the virus replicates by converting its RNA into DNA using an enzyme called reverse transcriptase. Sustiva works by blocking the action of reverse transcriptase, preventing the virus from multiplying and reducing the amount of virus in the body.

Sustiva may be prescribed as part of a combination therapy along with other antiretroviral drugs. Combination therapy is the standard treatment for HIV infection and has been shown to be more effective in delaying the progression of the disease and improving the patient’s quality of life.

Some of the other names for Sustiva include Stocrin and Avifanz.

How Does Sustiva Work?

Sustiva works by specifically binding to the reverse transcriptase enzyme, inhibiting its activity. By blocking this enzyme, Sustiva prevents the conversion of viral RNA into DNA, which is necessary for the virus to replicate and infect healthy cells.

Unlike other antiretroviral drugs that target the viral DNA directly, Sustiva acts by binding to a specific pocket on the reverse transcriptase enzyme, causing a conformational change that renders the enzyme inactive.

It is important to note that Sustiva should not be used as a monotherapy, as this can lead to the development of drug resistance. It is always prescribed in combination with other antiretroviral medications to increase effectiveness and reduce the chances of resistance.

Benefits of Sustiva Treatment

There are several benefits associated with Sustiva treatment for HIV-1 infection:

1. Reduction in viral load: Sustiva helps to decrease the amount of HIV in the blood, which can slow down the progression of the disease.
2. Improved immune function: By suppressing viral replication, Sustiva allows the immune system to recover and function better, reducing the risk of opportunistic infections.
3. Convenience: Sustiva is usually taken once daily, making it easier for patients to adhere to their medication regimen.
4. Tolerability: Sustiva is generally well-tolerated, with most side effects being mild to moderate and transient.

It is important for patients to adhere to their Sustiva regimen as prescribed by their healthcare provider to ensure the best possible outcomes.
