  • Common NRTIs include tenofovir, emtricitabine, and abacavir.
  • These drugs are often used in combination with other classes of HIV medications to form a complete regimen.

Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs)

  • NNRTIs also target the reverse transcriptase enzyme but do so in a different way than NRTIs.
  • Drugs like efavirenz, nevirapine, and rilpivirine fall into this class.
  • NNRTIs are usually taken in combination with other HIV drugs to prevent viral resistance.

Protease Inhibitors

  • Protease inhibitors block an enzyme called protease, which HIV needs to produce mature infectious viral particles.
  • Popular protease inhibitors include lopinavir, atazanavir, and darunavir.
  • These drugs are often used in combination with other classes of HIV medications to increase their effectiveness.

Fusion Inhibitors

  • Fusion inhibitors work by preventing HIV from entering human cells by blocking the fusion of viral and cellular membranes.
  • Enfuvirtide is an example of a fusion inhibitor prescribed to certain HIV patients.
  • These drugs are typically used in combination with other HIV medications.

Integrase Strand Transfer Inhibitors (INSTIs)

  • INSTIs target the integrase enzyme, which HIV uses to integrate its genetic material into the DNA of host cells.
  • Raltegravir, dolutegravir, and elvitegravir are common INSTIs prescribed for HIV treatment.
  • INSTIs are often part of initial combination therapies due to their potency and safety profile.
