Taffic 30mg (Bictegravir/Emtricitabine/Tenofovir Alafenamide)

Taffic 30mg is a fixed-dose antiretroviral medicine used in treating Human Immunodeficiency Virus-1 (HIV-1) disease. It is composed of three active ingredients:

1. Bictegravir (30mg) – An inhibitor of integrase-strand transfer (INSTI) which blocks the transfer of DNA from viruses into your host’s genome.
2. Emtricitabine (200mg) – a nucleoside reverse transcriptionase inhibitor (NRTI), which blocks the viral RNA-dependent DNA polymerase.
3. Tenofovir alafenamide (25mg) – A different NRTI, which is a precursor drug of tenofovir. It is activated within cells and stops HIV replication.

A combination of these medications can reduce the burden of viruses inside the body, ensure immunity, and ward off progression to Acquired Immunodeficiency Syndrome (AIDS).

Indications:

Taffic is approved for treatment of HIV-1 in adolescents and adults (aged 12 and over who weigh less than 35kg) with the following characteristics:

• Have no antiretroviral treatment history,
• Are they virologically suppressed (HIV-1 RNA < 50 copies/mL) with a long-lasting antiretroviral treatment regimen for at most three months, with no evidence of treatment failure or known mutations that could cause resistance to the components of the regimen.

Dosage and Administration:

• Recommended Dose: A tablet taken orally every day in combination with or without food.
• Route: Oral
• Form: Film-coated tablet

A dosage adjustment is not necessary for patients with mild or moderate kidney impairment. However, it’s not advised in patients suffering from extreme renal impairment (eGFR < 30 mL/min) or severely impaired liver function.

Mechanism of Action:

Each component functions at distinct phases of the HIV course of action:

• Bictegravir: It blocks the HIV integrase enzyme. It prevents the integration of viral DNA into host DNA.
• Emtricitabine and Tenofovir alafenamide: This block reverse transcriptase enzyme that is vital for the replication of viruses.

In combination, they decrease the capacity of HIV to reproduce and spread its virus into new cells.

Pharmacokinetics:

• Bictegravir: Half-life ~17.3 hours
• Emtricitabine: Half-life ~10 hours
• Tenofovir alafenamide: Intracellular half-life >150 hours

The majority of the medication is transformed through the liver (CYP3A, UGT1A1), which is followed by the elimination of feces and urine.

Contraindications:

• Hypersensitivity is a known reaction to a substance in the medication
• Utilizing concurrently with medicines that have strong stimulants to CYP3A and UGT1A1 (e.g. Rifampin, rifampin, carbamazepine, St. John’s Wort) because they can diminish bictegravir’s levels and diminish the effectiveness of the drug.

Warnings and Precautions:

1. Lactic Acidosis and Severe Hepatomegaly with Steatosis: In particular, with NRTIs. This includes deaths in some cases.
2. Hepatic Flares in Co-infected Patients: Patients suffering from Hepatitis B (HBV) can experience acute flare-ups of the hepatitis following discontinuation of the treatment.
3. Immune Reconstitution Syndrome: Inflammatory reactions can develop as the immune system is beginning to repair itself.
4. Drug Interactions: Beware of rifampin, anticonvulsants (e.g., phenytoin), as well as herbal supplements that stimulate CYP enzymes.
5. Renal and Hepatic Function: Check kidney function regularly, particularly for those suffering from kidney illness.
6. Bone Density Effects: Small reductions in mineral density of bone have been seen in a few patients.

Side Effects:

Common Side Effects (≥5%):

• Headache
• Diarrhea
• Nausea
• Fatigue
• Insomnia

Less Common but Serious:

• Lactic acidosis
• Hepatotoxicity
• Hypersensitivity reactions
• Exacerbation of HBV after discontinuation

Patients are advised to be aware of any symptoms that are unusual, including chronic fatigue, abdominal pain, or a yellowing appearance of the eyes or skin.

Use in Specific Populations:

• Pregnancy: Limitation on data. It should be employed only in cases where the benefits outweigh the risks.
• Lactation: Do not recommend. Breastfeeding mothers with HIV are not recommended as they are at risk of transmitting the virus.
• Pediatrics: Accepted by patients aged ≥12 years and ≥35kg.
• Geriatrics: Not much difference in terms of security. However, be cautious because of the possibility of decreased organ functioning.

Drug Interactions:

Avoid co-administration with:

• Rifampin
• Phenobarbital
• Carbamazepine
• St. John’s Wort
• Antacids containing aluminum or magnesium (should be taken 2 hours apart)

Caution with:

• Anticoagulants (e.g., dabigatran)
• Certain statins (e.g., atorvastatin – may need dose adjustment)
• Antifungals (e.g., ketoconazole – increases bictegravir levels)

Storage:

• Store at room temperature (20°C to 25°C)
• Place in the original container to keep moisture out
• Be sure to keep it out of the reach of young children

Frequently Asked Questions (FAQs)

What is Taffic 30mg used for?

Taffic is used for treating the HIV-1 virus in adults and adolescents. It reduces the amount of virus and boosts immunity.

How should I take Taffic 30mg?

Consume one tablet every day, either with or without food. Make sure to take it at the same time each day for the most effective outcomes.

Can I take Taffic with other HIV medications?

No, Taffic is a complete treatment. Don’t mix it with any other antiretrovirals, unless directed by your doctor.

What happens if I miss a dose?

If you’ve missed a dose, you should take the dose as soon as you can remember. If it’s near the next dose, avoid the one you missed. Do not mix it on.

Can I drink alcohol while taking Taffic?

Alcohol isn’t directly linked to traffic. However, excessive consumption could affect liver functioning. Be mindful of your consumption and talk to your physician.

Is Taffic safe during pregnancy?

There is only limited data available. Contact your physician if you’re expecting or intending to get pregnant.

Can I stop taking Taffic once my viral load is undetectable?

No. HIV treatment can last for life. Removing the drug could result in a relapse of the amount of virus and resistance to drugs.

What are signs of an allergic reaction to Taffic?

The symptoms include swelling, rash, and dizziness. It can also cause trouble breathing. Get medical attention right away in the event of these signs.

Will Taffic cure HIV?

No. Taffic is a virus-fighter, but it is not able to eliminate HIV. It can help keep HIV in a non-detectable state with frequent usage.

Can I breastfeed while on Taffic?

No. HIV is transmitted via the breastmilk of a mother. The practice of breastfeeding is not recommended for pregnant women with HIV.

Summary:

Taffic 30mg (Bictegravir/Emtricitabine/Tenofovir Alafenamide) is a once-daily, complete HIV-1 treatment regimen for adults and adolescents weighing at least 35 kg. It is a combination of three powerful antiretrovirals into a single tablet offering ease of use and superior efficacy for those who have not had prior treatment or for those who are currently virologically suppressed.

If you adhere to the treatment, Taffic helps maintain viral suppression, stop the progression of HIV, and improve the quality of life. Patients should continue treatment consistently and adhere to their doctor’s instructions. Although generally tolerated, tracking the kidneys, liver, and bone health is advised. Taffic cannot cure HIV, although it can play an important role in the longer-term treatment.
