Cabotegravir

Cabotegravir is a new type of HIV-1 prevention medicine that is taken as an injection every 8 weeks. It is a long-acting antiretroviral medicine that works by blocking a key protein needed for the virus to multiply. Cabotegravir is currently approved for use as a pre-exposure prophylaxis (PrEP) for adults at risk of HIV-1 infection. It is also being studied as a treatment for people who are already infected with HIV-1.

Cabotegravir: An Antiviral Medication for HIV

Cabotegravir, sold under brand names like Vocabria and Apretude, is an antiretroviral medication used to treat and prevent HIV infection. Here's a breakdown of its key characteristics:

Function:

  • Treatment of HIV-1: Used in combination with other antiretroviral medications for adults and adolescents over 12 years old to treat HIV-1 infection. By working together, these medications aim to suppress the virus and slow its progression to AIDS (acquired immunodeficiency syndrome).
  • Prevention of HIV-1: Recently approved for pre-exposure prophylaxis (PrEP) in adults and adolescents over 12 years old who are at high risk of acquiring HIV-1. PrEP involves taking medication to prevent HIV infection before potential exposure.

Mechanism of Action:

  • Belongs to a class of medications called integrase strand transfer inhibitors (INSTIs). These medications work by blocking the HIV integrase enzyme. This enzyme is essential for the virus to integrate its genetic material into the DNA of human cells, a crucial step for its replication. By blocking the integrase, cabotegravir prevents the virus from replicating and spreading in the body.

Formulations:

  • Available in two forms:
    • Tablets: Used for short-term (1 month) treatment or PrEP initiation to assess tolerability before switching to the injectable form.
    • Long-acting injectable: Administered by a healthcare professional every 2 months for treatment or every 8 weeks for PrEP. This long-acting form is a major benefit, offering increased adherence and potentially improved treatment outcomes compared to daily oral medications.

Important to Note:

  • Cabotegravir is not a cure for HIV infection. It should be used as part of a comprehensive treatment plan that may involve other medications.
  • It can cause various side effects, including:
    • Headache
    • Fever
    • Fatigue
    • Muscle aches
    • Injection site reactions (with the injectable form)
  • Cabotegravir has interactions with other medications. It's crucial to inform your doctor about all medications you are taking before starting cabotegravir.
