Vocabria, enriched with the powerful ingredient Cabotegravir, stands as a remarkable exemplar in the realm of antiretroviral medications. Cabotegravir belongs to the class of drugs known as integrase strand transfer inhibitors (INSTIs). These are a newer generation of antiretrovirals that have garnered significant attention due to their efficacy and distinct mode of action against HIV.

Zidovudine, widely recognized in the medical community, is a prominent member of the nucleoside reverse transcriptase inhibitors (NRTIs) family. These inhibitors play an indispensable role in the world of antiretroviral therapy. What makes NRTIs, and particularly Zidovudine, so effective is their strategic targeting and interference with a key process the HIV relies upon: the replication of its genetic material.
