Description

What is Atazor R?

Atazor R is an antiretroviral medication used to treat HIV-1 infection.
It is a combination therapy containing:

  • Atazanavir (a Protease Inhibitor)

  • Ritonavir (a booster that increases the effectiveness of Atazanavir)

Composition

Each tablet typically contains:

(Strengths may vary depending on the exact product variant.)

Working (Mechanism of Action)

Atazanavir

  • Inhibits the HIV protease enzyme

  • Prevents new viral particles from maturing

  • Slows viral replication

Ritonavir

  • Inhibits liver enzymes that metabolize Atazanavir

  • Boosts Atazanavir levels → makes it more effective

Together, they reduce viral load and increase CD4 counts.
