Atavir Capsule (Atazanavir)

Description

Atavir 300 (Atazanavir 300mg) Capsules

Atavir 300 contains atazanavir 300mg, an antiviral medicine in the HIV protease inhibitor class. Atazanavir is used with other antiretroviral medicines to treat HIV-1 infection. The product shown here is Atavir 300 from Cipla and contains 30 capsules.

Atavir 300 Atazanavir: What Is It?

Atavir 300 is a prescription capsule containing atazanavir 300mg. The product shown in the image is manufactured by Cipla and contains 30 capsules.

Atazanavir belongs to a group of HIV medicines called protease inhibitors. It works by blocking HIV protease, an enzyme that HIV needs to produce mature infectious virus.

Because atazanavir forms part of combination HIV treatment, patients should take it with the other medicines prescribed by their healthcare professional.

Atavir 300 Atazanavir Uses

Atavir 300 is used as part of combination treatment for HIV-1 infection.

Atazanavir reduces the amount of HIV in the blood by interfering with viral maturation. Consequently, combination antiretroviral therapy can reduce viral replication and support immune function.

However, atazanavir does not cure HIV. Therefore, patients should continue their complete prescribed treatment regimen even when they feel well.

What Is Atazanavir Used For?

Atazanavir is an antiretroviral medicine used for the treatment of HIV-1 infection. It belongs to the protease inhibitor class.

Current U.S. prescribing information describes atazanavir as a medicine used in combination with other antiretroviral agents. The exact regimen depends on factors such as previous treatment, resistance, age, kidney function, liver function, and other medicines.

For that reason, Atavir 300 should not be used as a stand-alone HIV treatment.

How Does Atavir 300 Atazanavir Work?

Atazanavir inhibits HIV protease. This enzyme helps HIV produce mature infectious viral particles.

When protease activity is blocked, newly produced viral particles cannot mature normally. As a result, atazanavir helps reduce the production of infectious HIV.

Nevertheless, the medicine does not remove HIV from the body. Effective treatment therefore requires an appropriate combination antiretroviral regimen.

Atavir 300 Composition

• Active ingredient: Atazanavir
• Strength: 300mg
• Dosage form: Capsule
• Drug class: HIV protease inhibitor
• Brand: Atavir 300
• Manufacturer/marketer shown: Cipla
• Pack shown: 30 capsules

Atazanavir 300mg Dose

The appropriate atazanavir dose depends on the complete HIV treatment regimen and the patient’s clinical situation.

Current U.S. prescribing information for atazanavir includes the following adult regimens:

• Treatment-naive adults: 300mg with ritonavir 100mg once daily with food, or 400mg once daily with food in appropriate patients.
• Treatment-experienced adults: 300mg with ritonavir 100mg once daily with food.

Concomitant medicines can change the recommended dose. In addition, kidney or liver impairment may require treatment modification.

Therefore, do not assume that every person taking atazanavir should use 300mg alone.

For current prescribing information, review the DailyMed atazanavir prescribing information.

How to Take Atavir 300

Take Atavir exactly as prescribed by your healthcare professional.

• Take atazanavir with food.
• Take it at approximately the same time each day.
• Swallow the capsule whole.
• Do not open the capsule unless a healthcare professional specifically instructs you to do so.
• Continue the other antiretroviral medicines in your prescribed regimen.
• Do not stop treatment without medical advice.

Taking atazanavir consistently helps maintain appropriate medicine levels. Therefore, try to follow the same daily schedule.

Atavir 300 Atazanavir Side Effects

Atazanavir can cause side effects, although not everyone experiences them.

Possible reactions include:

• Nausea
• Headache
• Diarrhea
• Vomiting
• Dizziness
• Rash
• Changes in bilirubin levels

Some people develop increased bilirubin without significant liver injury. However, unusual or severe symptoms should still be discussed with a healthcare professional.

Serious Atazanavir Side Effects

Atazanavir has important safety warnings. Serious reactions can include severe skin reactions, liver problems, gallbladder problems, kidney stones, and changes in heart rhythm.

Seek prompt medical attention if you develop:

• Severe or widespread skin rash
• Blistering or peeling skin
• Yellowing of the skin or eyes
• Severe abdominal pain
• Fainting or severe dizziness
• Irregular heartbeat
• Severe weakness

Atazanavir can also increase bilirubin. Therefore, healthcare professionals may monitor liver-related laboratory results during treatment.

Atazanavir and Bilirubin

Atazanavir commonly affects bilirubin levels because it inhibits an enzyme involved in bilirubin processing.

As a result, some patients develop elevated indirect bilirubin or yellowing of the skin or eyes. This does not always mean that the liver has been damaged.

Nevertheless, new or worsening jaundice should be evaluated by a healthcare professional.

Atazanavir and Food

Atazanavir capsules should be taken with food. Food improves absorption and helps the medicine reach appropriate levels in the body.

Therefore, do not routinely take Atavir 300 on an empty stomach unless your healthcare professional provides different instructions for your specific regimen.

Atazanavir and Ritonavir

Ritonavir is commonly used as a pharmacokinetic booster with atazanavir. It inhibits CYP3A enzymes and increases atazanavir exposure.

This boosting effect allows a 300mg atazanavir dose to be used in several established treatment regimens.

However, ritonavir also interacts with many other medicines. Consequently, healthcare professionals should review the complete medication list before treatment begins.

Atazanavir and Cobicistat

Cobicistat can also boost atazanavir by increasing its concentration in the body.

However, cobicistat availability and product labeling differ by country. In the United States, cobicistat as a standalone product has been discontinued, although it remains present in certain fixed-dose combination products.

Therefore, patients should follow the specific booster regimen prescribed by their healthcare professional.

Atavir 300 Atazanavir vs Darunavir

Atazanavir and darunavir are both HIV protease inhibitors. However, they are different active ingredients with different dosing, interactions, resistance profiles, and clinical considerations.

Neither medicine is automatically better for every patient. Treatment selection should follow current HIV guidelines and individual clinical factors.

Atazanavir and Nelfinavir

Nelfinavir is another protease inhibitor that has been used in HIV treatment. However, HIV treatment has changed substantially over time, and many current regimens favor newer medicines.

Therefore, historical use of nelfinavir should not be interpreted as a recommendation for a modern HIV regimen.

Atazanavir and Tenofovir

Atazanavir can be used with certain NRTIs, including tenofovir-based medicines, depending on the treatment regimen.

However, tenofovir can affect atazanavir exposure and may change the recommended atazanavir regimen. Consequently, healthcare professionals need to consider the complete combination before prescribing.

Atazanavir and Emtricitabine

Atazanavir can appear in HIV treatment combinations containing emtricitabine and another NRTI. The exact combination depends on the patient’s treatment plan.

Patients should not add or remove emtricitabine independently. Instead, follow the complete regimen prescribed by the HIV treatment team.

Atazanavir Drug Interactions

Atazanavir has many clinically important drug interactions because it affects CYP3A and other drug-transport pathways.

Tell your healthcare professional about every medicine, vitamin, supplement, and herbal product you use.

Important interaction categories include:

• Strong CYP3A inducers
• Certain cholesterol-lowering medicines
• Some sedatives
• Certain erectile dysfunction medicines
• Acid-reducing medicines
• Some antiarrhythmic medicines
• Certain anticonvulsants
• St. John’s wort

Because interaction rules can be complex, do not start or stop another medicine without checking with your healthcare professional.

Atazanavir and Antacids

Medicines that reduce stomach acidity can lower atazanavir absorption.

Antacids and buffered medicines may need to be separated from atazanavir. H2-receptor antagonists and proton-pump inhibitors can require additional restrictions or dose adjustments.

Therefore, tell your doctor or pharmacist about medicines such as omeprazole, pantoprazole, famotidine, or antacid products before taking Atavir 300.

Atazanavir and St. John’s Wort

St. John’s wort can reduce concentrations of several antiretroviral medicines.

For that reason, current prescribing information lists St. John’s wort among medicines that should not be combined with atazanavir.

Do not use herbal supplements containing St. John’s wort without discussing them with your healthcare professional.

Atavir 300 Atazanavir and Kidney Function

Tell your healthcare professional if you have kidney disease or a history of kidney stones.

Atazanavir has been associated with nephrolithiasis and, less commonly, kidney-related complications. Therefore, clinicians may consider kidney function and the patient’s medical history when selecting treatment.

Atazanavir and Liver Disease

Liver function can influence atazanavir treatment decisions because the medicine undergoes hepatic metabolism.

Tell your healthcare professional if you have hepatitis, cirrhosis, or another liver condition. Moderate or severe hepatic impairment can require changes to the regimen.

Atazanavir and Heart Rhythm

Atazanavir can prolong the PR interval in some people. Patients with existing conduction abnormalities or those taking other medicines that affect cardiac conduction may require additional caution.

Tell your healthcare professional if you have a history of abnormal heart rhythm, fainting, or heart disease.

Atazanavir During Pregnancy

Tell your healthcare professional if you are pregnant, planning pregnancy, or breastfeeding.

Pregnancy can affect antiretroviral treatment decisions. Therefore, people who are pregnant should receive individualized advice from an HIV specialist or qualified healthcare professional.

Do not stop HIV treatment independently because of pregnancy. Instead, discuss the complete treatment plan with your healthcare team.

Atazanavir and Breastfeeding

Discuss breastfeeding with your healthcare professional before starting or continuing atazanavir.

HIV can be transmitted through breast milk. Therefore, infant-feeding recommendations should follow current local and clinical guidance.

Can Atazanavir Cure HIV?

No. Atazanavir does not cure HIV.

Instead, it reduces HIV replication as part of combination antiretroviral therapy. Effective treatment can reduce viral load and help protect immune function.

Patients should continue their complete HIV regimen unless their healthcare professional changes the treatment plan.

What Happens If You Miss an Atavir 300 Dose?

If you miss a dose, follow the instructions provided by your healthcare professional or pharmacist.

Do not take an extra dose unless specifically instructed. Try to take Atavir at the same time each day to maintain a consistent treatment routine.

Can I Stop Atavir 300 When I Feel Better?

No. Do not stop Atavir without medical advice.

HIV can begin replicating again when antiretroviral treatment stops. In addition, treatment interruption can increase the risk of resistance.

Therefore, discuss any concerns about side effects, cost, availability, or treatment changes with your healthcare professional before stopping the medicine.
