How do the following HIV antiretroviral drugs work? - CCR5 inhibitors
Black HIV binding to the ccr5 co receptor
How do the following HIV antiretroviral drugs work? - fusion inhibitors
Block HIV from fusing to anchor proteins in the host cell membrane
How do the following HIV antiretroviral drugs work? - nucleoside/ nucleotide reverse transcriptase inhibitors and non-nucleiside reverse transcriptase inhibitors
Black HIV from using reverse transcriptase enzyme to convert single stranded RNA into double stranded DNA
How do the following HIV antiretroviral drugs work? - integrase inhibitors
Black HIV from using integrase enzymes to insert viral DNA into the host DNA
How do the following HIV antiretroviral drugs work? - protease inhibitors
Black proteases that cleave long chains of HIV proteins into smaller HIV proteins that are packed together to form the new HIV virus
Nucleoside/nucleotide reverse transcriptase inhibitor developed in 1987 that reduces mortality and opportunistic infections, delays progression to AIDS, and reduces maternal to infant transmission of HIV. However resistance develops
Zidovudine (ZDV or AZT)
