They work by blocking the action of reverse transcriptase, an enzyme that HIV uses to convert its RNA into DNA, a crucial step in the virus's replication cycle [1].

Several alternative medications and treatment regimens are available for both HIV treatment and PrEP. For HIV treatment, these include other combinations of NRTIs, integrase strand transfer inhibitors (INSTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), and protease inhibitors.
