Active Ingredients and Mechanism of Action

**Active Ingredients and Mechanism of Action** Cabenuva, a long-acting injectable antiretroviral therapy, consists of two active ingredients: cabotegravir and rilpivirine. These components work synergistically to suppress the replication of the human immunodeficiency virus (HIV) in the body. **Cabotegravir** is an integrase strand transfer inhibitor (INSTI), which blocks the integration of HIV genetic material into the host cell's DNA. This integration is a crucial step in the viral replication cycle, as it allows the virus to insert its genetic code into the host cell's genome. By inhibiting this process, cabotegravir prevents the virus from replicating and producing new viral particles. **Rilpivirine** is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It binds to the reverse transcriptase enzyme, which is essential for converting the viral RNA into DNA. This binding causes a conformational change in the enzyme, rendering it inactive and thus preventing the reverse transcription process. Without reverse transcription, the virus cannot convert its RNA genome into DNA, which is necessary for its replication. The **mechanism of action** of Cabenuva involves the combined effects of these two drugs. When administered via injection, cabotegravir and rilpivirine are slowly released into the bloodstream, maintaining therapeutic levels over an extended period. This sustained release ensures consistent suppression of viral replication, reducing the viral load in the body. By targeting different stages of the HIV life cycle—integration and reverse transcription—Cabenuva provides a robust and comprehensive approach to managing HIV infection, making it an effective treatment option for individuals living with HIV-1 infection. This dual-action mechanism not only helps in achieving and maintaining viral suppression but also reduces the risk of drug resistance by targeting multiple pathways of viral replication.

Administration and Dosage Guidelines
