Atazor-R 300mg/100mg Tablet is a combination of two anti-HIV medicines: Atazanavir and Ritonavir. They work by interfering with an enzyme (protease), which is required by HIV-infected cells to make new viruses. This stops the production of new viruses.
Atazanavir is rapidly absorbed and administration of a single dose of atazanavir with a light meal resulted in a 70% increase in area under the plasma concentration-time curve (AUC); therefore atazanavir should be taken with food. Atazanavir is 86% bound to human serum protein independently of concentration.The pharmacokinetics of ritonavir are relatively linear after multiple doses, with apparent oral clearance averaging 7 to 9 L/h. In vitro, ritonavir is a potent inhibitor of CYP3A.
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

Atazanavir
Q. What is Atazanavir used for?
Atazanavir is used in combination with other anti-retroviral medicines for the treatment of human immunodeficiency virus (HIV-1) infection
Q. Does Atazanavir cause hyperbilirubinemia?
Yes, hyperbilirubinemia (an increase in the level of bilirubin in the blood) is a known side effect of Atazanavir.
Q. How does Atazanavir work?
Atazanavir belong to a group of medications called azapeptide HIV-1 protease inhibitor. It inhibits some viral polypeptides in the HIV-1 infected cells of the body and inhibits and prevents maturation of virus in the cells. Atazanavir does not cure HIV infections; it decreases the risks of developing acquired immunodeficiency syndrome (AIDS) and other HIV-related illnesses due to compromised immunity
Q. Does Atazanavir cause lipodystrophy?
Yes, lipodystrophy (changes in body fat - build up or loss of body fat) is a known side effect of Atazanavir
Ritonavir
Q. What is Ritonavir used for?
It is used along with other medication for treating human immunodeficiency virus (HIV) infection. It does not completely cure HIV or AIDS
Q. Why is ritonavir used along with lopinavir?
Ritonavir is available with lopinavir as a fixed dose combination as it improves the availability of lopinavir which helps in increasing activity against HIV
Q. Is ritonavir a protease inhibitor?
Ritonavir, a protease inhibitor
Q. How does Ritonavir work and what does it inhibit?
Ritonavir belongs to a class of medication called protease inhibitors. It inhibits protease enzymes from breaking down proteins and thus prevents HIV from multiplying inside the body. It does not cure HIV completely but reduces the chances of getting acquired immunodeficiency syndrome (AIDS) and HIV related infections or cancer
Q. Why is it used as a booster?
Ritonavir is used as a booster to increase the absorption of other protease inhibitors as well as prevent other protease inhibitors from being degraded.
