How do retroviral drugs work? Cite Sources?

Answer 1

Are you asking about ANTIretroviral drugs?

Have a look at the Wiki page - they have a good list of sources

There are
REVERSE TRANSCRIPTASE INHIBITORS which block the retroviral reverse transcriptase protein and stop the viral genome from being made into a form where it can slip into our genome.

PROTEASE INHIBITORS inhibit the protease used in the final assembly and release of virus particles

FUSION INHIBITORS stop the virus from entering the human cell membrane by preventing viral fusion with the cell membrane

INTEGRASE INHIBITORS are soon to come - they stop the viral genetic code from being integrated into the human DNA

ENTRY INHIBITORS stop the virus from binding to the CD4 T-helper cell (the virus normally binds at the membrane receptor) therefore stopping virus entry into the cell

MATURATION INHIBITORS prevent the viral capsid from being fully processed and ready for the virus to be put into it - this prevents the formation of new virus particles
