HIV Meds Flashcards
what does HAART stand for
Highly active antiretroviral therapy
6 steps to HIV replication
entry (binding and fusion)
reverse transcription
integration
replication (transcription and translation)
assembly
budding and maturation
CCR5 antagonist
Maraviroc
what do you have to use for pt prior to initiating a CCR5 antagonist
tropism assay
fusion inhibitors
Enfuvirtide (T-20)
MOA fusion inhibitors
bind to envelope glycoprotein 41 to prevent viral fusion to CD4 T cell
attachment inhibitors
Fostemsavir
Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs)
Abacavir
Emtricitabine
Lamivudine
Stavudine
Tenofovir alafenamide
Tenofovir disoproxil fumarate
Zidovudine
what strands are NRTIs active against
HIV 1 and HIV 2
what NRTIs are active against hepatitis B
Lamivudine
Emtricitabine
Tenofovir
MOA NRTIs
intracellular phosphorylation –> active triphosphate form inhibits oral replication through competitive binding
BBW for NRTIs
lactic acidosis
what do you have to test before starting Abacavir
HLA-B*5701
who should avoid Abacavir
those who test positive for HLA-B*5701
CAD and risk factors for CAD
what NRTIs should not be combined
lamivudine and emtricitabine – they are structurally similar and will compete
main ADE of tenofovir
kidney injury
bone loss
what was the first antiretroviral med for HIV
Zidovudine
what NRTI significant reduces in utero transmission from mother to fetus and is often given during L&D
Zidovudine
what medication should not be used with zidovudine
stavudine
what GI illness is lamivudine associated with
pancreatitis
what NRTI combo is technically first line
Abacavir/Lamivudine
what does TAF stand for
tenofovir alafenamide
what does TDF stand for
tenofovir disoproxil fumarate
between TAF and TDF, which is administered at lower doses
TAF (TAF will have decreased plasma levels but increased intracellular concentrations)
