One of its main objectives is to avoid infected individuals from acquiring AIDS, a kind of chronic disease brought about by the human immunodeficiency virus. If Truvada is consumed as what is being instructed for individuals to do, the treatment is also expected to be a successful undertaking.

As mentioned here, Truvada is also one of those drugs with dual purposes. First, this ART is made for treating the infection – HIV. Secondly, it is also classified as a drug for PrEP. This medicine is not only produced for inhibiting the virus inside the body but also prevents someone’s possible infection of the human immunodeficiency virus.

How does it work?

As identified with other ARTs available, there are a specific group of medicines that provide medical relief to several infections. As for Truvada, this antiretroviral drug associates itself with the family of nucleoside reverse transcriptase inhibitors. NRTIs like Truvada aim to block the process of reproduction that HIV continues to do within our bodily systems.

Truvada’s main components are emtricitabine and tenofovir. Combined to one, the body is given the support to fight back and hinder other forms of illness to emerge. Additionally, when Truvada is used as a preventive drug, it is very much capable of lessening someone’s possibility of getting infected. The drug acts as a protective barrier against HIV’s life-threatening impact.
