Sustiva (Efavirenz) – An Effective Antiviral Drug for HIV Treatment

Sustiva (Efavirenz): An Effective Antiviral Drug for HIV Infection Treatment

Sustiva, also known as Efavirenz, is a highly potent antiviral drug specifically developed to combat Human Immunodeficiency Virus (HIV) infection. It belongs to the prestigious class of non-nucleoside reverse transcriptase inhibitors (NNRTIs) which have proven to be effective in suppressing the replication of the virus within the body.

What is Sustiva?

Sustiva, or Efavirenz, is an oral medication predominantly used in combination with other antiretroviral drugs for the treatment of HIV-1 infection in both adult and pediatric patients. It acts by inhibiting the reverse transcriptase enzyme, an essential protein responsible for the replication of the viral DNA.

How does Sustiva work?

By binding to the reverse transcriptase enzyme, Sustiva effectively blocks the conversion of viral RNA into DNA, thus preventing the virus from infecting healthy cells and replicating itself. This inhibitory action significantly reduces the viral load in HIV-infected individuals and helps to maintain or improve the overall immune function of the patient.

Main features of Sustiva:

Drug Name	Sustiva (Efavirenz)
Drug Class	Non-nucleoside reverse transcriptase inhibitors (NNRTIs)
Indications	Treatment of HIV-1 infection in adults and pediatric patients (weighing at least 40kg or 88lb)
