• Avoid consuming alcohol or using recreational drugs while taking ritonavir, as they may interact with the medication and cause adverse effects.

Some of the specific indications for Ritomune Tablet (Ritonavir/Norvir) include

• HIV Treatment: Ritonavir is Life-Saving Drug, primarily used as part of combination therapy to treat HIV infection. It belongs to a class of medications called protease inhibitors, which work by inhibiting the replication of the virus and reducing the viral load in the body.
• Boosting Other HIV Medications: Ritonavir/Norvir is often used as a "booster" medication to enhance the effectiveness of other protease inhibitors. It is used in lower doses to increase their concentration in the blood, allowing for better control of HIV.
• Prevention of Mother-to-Child Transmission: Ritonavir may be used during pregnancy to reduce the risk of transmitting HIV from mother to child. It is part of a comprehensive antiretroviral regimen prescribed by healthcare providers for pregnant women with HIV.
• Post-Exposure Prophylaxis (PEP): In certain situations, such as occupational exposure to HIV, ritonavir may be used as part of a post-exposure prophylaxis regimen to prevent HIV infection.
• Off-Label Uses: Ritonavir may also be used off-label for other conditions, as determined by healthcare providers. These uses may include the treatment of certain viral infections or as a component of experimental therapies.

Is Ritonavir/Norvir a protease inhibitor? What is it used for?

Ritonavir belongs to a class of medications called protease inhibitors. It is used in combination with other drugs for the treatment of human immunodeficiency virus (HIV) infection. Ritonavir does not provide a complete cure for HIV but reduces the risk of developing acquired immunodeficiency syndrome (AIDS), HIV-related infections, or cancer.

How does Ritonavir work, and what does it inhibit?

Ritonavir inhibits protease enzymes responsible for breaking down proteins, thereby preventing the multiplication of HIV within the body. It does not cure HIV completely but reduces the risk of developing AIDS and HIV-related infections or cancer.

Why is Ritonavir used together with lopinavir? Why is it considered a booster?

Ritonavir is available in a fixed-dose combination with lopinavir because it enhances the availability and effectiveness of lopinavir against HIV. Ritonavir is used as a booster to increase the absorption of other protease inhibitors and prevent their degradation.

Some of the notable interactions with Ritomune Tablet (Ritonavir) include:

Ritonavir/Norvir can interact with various medications, potentially affecting their effectiveness or leading to adverse effects. 

• Other HIV Medications: Ritonavir is frequently used as a booster for other protease inhibitors, increasing their levels in the blood and enhancing their efficacy. Commonly combined with drugs like Atazanavir, Lopinavir, and Darunavir.
• Antifungal Drugs: Azole antifungals (e.g., Ketoconazole) can interact with Ritonavir, leading to increased levels of both drugs in the bloodstream.
• Certain Antibiotics: Macrolide antibiotics (e.g., Clarithromycin, Erythromycin) should be used with caution due to potential interactions with Ritonavir.
• Some Heart Medications: Drugs like Amiodarone and Quinidine may interact with Ritonavir, affecting heart rhythm.
