Final answer:
Integrase inhibitors are antiviral medications that block the HIV integrase, preventing the integration of the viral genome into the host cell chromosome. There are also other classes of antiviral drugs used to treat HIV.
Step-by-step explanation:
Integrase inhibitors are a type of antiviral medication that target the HIV integrase, which is responsible for integrating the viral genome into the host cell chromosome. By blocking this process, these inhibitors prevent the replication of the virus. Examples of integrase inhibitors include raltegravir and dolutegravir.
In addition to integrase inhibitors, there are other classes of antiviral drugs used to treat HIV. These include reverse transcriptase inhibitors, protease inhibitors, fusion inhibitors, and CCR5 antagonists.
