How does combination of Atazanavir and Ritonavir work?
Atazanavir and Ritonavir are both protease inhibitors, which means they work by blocking the protease enzyme that HIV needs to replicate. Atazanavir directly inhibits this enzyme, preventing the virus from maturing and multiplying. Ritonavir, while also a protease inhibitor, is primarily used in lower doses to boost the effectiveness of Atazanavir by inhibiting the enzyme that breaks down Atazanavir, thereby increasing its concentration in the blood. Together, they effectively reduce the viral load in the body.
How long does it take for combination of Atazanavir and Ritonavir to work?
Atazanavir and Ritonavir are both antiretroviral medications used to treat HIV. Atazanavir typically starts working within a few hours after ingestion, as it is absorbed and begins to inhibit the virus's protease enzyme, which is crucial for viral replication. Ritonavir, on the other hand, is often used in lower doses to boost the effectiveness of other protease inhibitors like Atazanavir. It also starts working within a few hours by inhibiting the same enzyme and enhancing the concentration of Atazanavir in the bloodstream. Together, they work synergistically to reduce the viral load in the body, although noticeable clinical improvements may take several weeks.
How does one take combination of Atazanavir and Ritonavir?
Atazanavir and Ritonavir should both be taken with food to enhance absorption and effectiveness. It is important to take these medications at the same time each day to maintain consistent drug levels in the body. Patients should avoid taking these medications with high-fat meals, as this can affect absorption.
