Overview

What is Atazanavir?

Atazanavir is an HIV protease inhibitor with the advantage of once-daily dosing and minimal effect on cholesterol. It is typically boosted with ritonavir or cobicistat and used in combination ART regimens.

Mechanism

How Does It Work?

Protease inhibition

Atazanavir blocks HIV-1 protease, preventing cleavage of polyprotein precursors required for viral maturation.

Immature virion formation

Without functional protease, HIV produces non-infectious particles that cannot initiate new infections.

Once-daily convenience

Atazanavir's long half-life supports simple once-daily dosing with a good adherence profile.

FAQ

Frequently Asked Questions

Why does Anzavir-r Tablet cause yellow skin or eyes?

Atazanavir causes a harmless rise in indirect bilirubin in most patients, resulting in yellowing of the skin or whites of the eyes. This is a cosmetic effect and does not indicate liver damage, but should be reported to your doctor.

Is Atazanavir safe with acid reflux medication?

Atazanavir absorption depends on stomach acid. Proton pump inhibitors (PPIs) can reduce its levels significantly. If you need acid reflux treatment, your doctor may prescribe H2 blockers instead and will adjust timing carefully.

Can I take Anzavir-r Tablet once a day?

Yes. Atazanavir is dosed once daily, which simplifies your HIV regimen and supports adherence. It is usually taken once daily with ritonavir 100 mg or cobicistat 150 mg as a booster.

How does Atazanavir compare to other HIV protease inhibitors?

Atazanavir is favoured for its minimal effect on cholesterol and triglycerides compared to other PIs. However, it can cause kidney stones and requires food for absorption. Your doctor will choose the best PI for your clinical situation.
