Antivirals Flashcards
Classes of HIV drugs
NRTI
NNRTI
Protease inhibitors
INSTIs
MOA of NRTI
nucleoside analog inhibits reverse transcriptase which inhibits cDNA

bone marrow suppression
pancreatitis
peripheral neuropathy
hepatotoxicity
lactic acidosis
nephrotoxicity
NNRTI HIV drugs
“-vir-“
AE’s of HIV NNRTI
depression
hepatotoxicity
QTc prolongation
IRIS
HIV protease inhibitor drugs
“-navir”
MOA of NNRTI
bind to reverse transcriptase and inhibit cDNA
MOA of protease inhibitors
bind to protease which inhibits protein cleavage and inhibits new viral progeny
AE’s of HIV protease inhibitors
PR prolongation
QTc prolongation
hyperglycemia
hepatotoxicity
hyperlipidemia
pancreatitis
increases bleeding (no hemophiliacs)
IRIS
Avoid in patients at risk of phenylketonuria
Caution w/ sulfa allergy
MOA of INSTIs
inhibit integrase which inhibits DNA transfer which inhibits new viruses
HIV INSTI drugs
“-tegr-“
Special consideration for raltegravir?
Avoid in patients at risk for phenylketonuria
AE’s of INSTIs
nephrotoxicity
lactic acidosis
hepatotoxicity
depression
IRIS
Classes of Influenza drugs
Neuraminidase inhibitors
Polymerase acidic protein endonuclease inhibitor
MOA of neuraminidase inhibitors
bind to viral neuraminidase which inhibits the release of virus from sialic acid and inhibits viral spreading
Neuraminidase inhibitor drugs?

Zanamivir (Relenza)
Peramivir (Rapivab)
Tamiflu: treatment or prophylaxis?
both
Relenza: treatment or prophylaxis?
both
Rapivab: treatment or prophylaxis?
treatment only
AE’s of Tamiflu?
Skin rxn
Neuropsych rxn
Special consideration for Relenza?
Not used in asthma/COPD
AE’s of Rapivab?
Skin rxn
hallucinations
neuropsych rxn
MOA of PA protein endonuclease inhibitor?
inhibit endonuclease which inhibits insertion of viral RNA and inhibits viral replication
PA protein endonuclease inhibitor drug?
Baloxavir marboxil (Xofluza)
