Twinaqt (Dolutegravir/Lamivudine)

Once-Daily, Fixed-Dose Combination Tablet for HIV-1 Treatment

Overview

Twinaqt is a fixed-dose combination tablet containing two powerful antiretroviral agents — Dolutegravir and Lamivudine. It is used as a daily oral medicine for the treatment of HIV-1-related infections for both adolescents and adults.

In combining the two drugs in a single tablet, Twinaqt streamlines the antiretroviral (ART) regimen, increasing the adherence of patients and improving treatment results. It’s designed to be used by people who have never been treated (those who are starting HIV therapy for the very first time) and also for patients who have been suppressed virologically or switching to various treatment regimens.

Composition

Each Twinaqt tablet contains:

• Dolutegravir 50 mg
  An integrase strand transfer inhibitor (INSTI) that blocks HIV from infiltrating its genetic material into the host’s DNA and thus hinders replication by HIV.
• Lamivudine 300 mg
  Nucleoside reverse transcriptase inhibitor (NRTI), which blocks the reverse transcriptase enzyme. It prevents the process of converting viral RNA to DNA. An essential step in the HIV course.

Mechanism of Action

Dolutegravir:

Dolutegravir can bind to the HIV Integrase enzyme and prevents the integration of virus DNA into the host genome, and is crucial to viral replication as well as the infection of cells that are not yet infected. It is characterized by the benefit of a strong barrier against resistance and has potency against strains that are intolerant to the other INSTIs.

Lamivudine:

Lamivudine mimics nucleosides found in nature and integrates into viral DNA in reverse transcription. It causes premature end of DNA chains as well as stopping the replication of viral DNA.

Indications

• Treatment for HIV-1 disease for adolescents and adults (≥12 years old, weighing ≥40 kg).
• It is used as a first-line therapy for patients who are not receiving treatment or as a preventative therapy for patients who are already blocked by other treatments.
• A component of combination treatment, typically prescribed along with other antiretroviral medications according to a medical examination.

Dosage and Administration

• Recommended Dose: A Tablet from Twinaqt (Dolutegravir 50 mg + Lamivudine 300 mg) each day, either with or without food.
• Duration: A life-long and continuous treatment as recommended by your healthcare professional.
• Missed Dose: If you do not take a dose within 12 hours, you should make sure to take it as soon as you can remember. If it is more than 12 hours later, do not take the missed dose and start the subsequent dose at the scheduled time. Do not increase the dose.

Benefits of Twinaqt

• A simple, once-daily schedule increases adherence and decreases the weight of the pill.
• Potent viral suppression leading to improved immune function and reduced risk of HIV progression.
• A potent inhibitor of HIV that results in better immune function as well as a reduced chance of HIV progression.
• Very well-liked with a good adverse effect on the profile.
• Lowers the viral load down to unnoticeable levels and reduces the possibility of HIV transmission.
• Helps to support the immune system through the increase of CD4+ cells.
• Incompatible with other antiretroviral medicines, giving the possibility of a variety of treatments.

Precautions and Warnings

• Hypersensitivity reactions: A few serious allergic reactions may occur. Do not stop treatment immediately if you notice signs such as fever, rash, or organ malfunction develop.
• Liver disease: Check on patients who have Hepatitis B or C concomitant infections closely, as withdrawal could trigger flare-ups.
• Pregnancy: Dolutegravir can carry a minor chance of neural tube defects when it is taken before conception or in the early stages of pregnancy. Women who have the potential to become pregnant must talk about contraceptive plans and pregnancy with their doctor.
• Drug Interactions: Dolutegravir and Lamivudine can interact with various medications, such as certain antiacids, such as rifampin, metformin, and others. Be sure to inform your physician of any medications or supplements.
• Immune Reconstitution Inflammatory Syndrome (IRIS): In rare cases, improvements in immunity can cause an inflammation response in the face of existing illnesses.
• Renal Impairment: Lamivudine is eliminated by the kidneys. It is possible to adjust dosages in patients who have diminished renal function.

Possible Side Effects

The majority of patients take Twinaqt quite well. Certain patients may experience:

Common Side Effects:

• Headache
• Nausea
• Diarrhea
• Fatigue
• Insomnia
• Dizziness

Less Common but Serious Side Effects:

• Hypersensitivity reactions (rash, fever)
• Liver toxicity (jaundice, elevated liver enzymes)
• Psychiatric symptoms (depression, anxiety, mood changes)
• Lactic acidosis (rare but serious metabolic condition)
• Pancreatitis (inflammation of the pancreas)

Get in touch with your doctor immediately if there is a serious irritation, trouble breathing, and nausea that persists, abdominal pains, or if you experience unusual fatigue.

Drug Interactions

• Antacids and mineral supplements (calcium, iron, magnesium) could reduce the absorption of dolutegravir. Take this at least 2 hours prior to or at least 6 hours following Twinaqt.
• Rifampin, as well as other antibiotics, could reduce dolutegravir levels. Dose adjustments may be necessary.
• Metformin: Dolutegravir increases metformin levels and also monitors for signs of hypoglycemia.
• Beware of co-administration with St. John’s Wort (a herbal supplement) since it reduces dolutegravir levels.
• Make sure you inform your physician regarding all medications, not just OTC medications, as well as supplements.

Storage

• Place in storage in the room temperatures (20–25°C).
• Protect from moisture and direct sunlight.
• Be sure to keep away from young children.
• Use only any products after the expiration date listed on the packaging.
