Antiretrovirals Flashcards
What does NRTI stand for?

List three NRTIs.
Abacavir
Zidovudine
Lamivudine
Emtricitabine
What is the MOA of the NRTIs?
Analogs of nucleotides that inhibit nucleotide binding to REVERSE TRANSCRIPTASE and cause DNA chain termination
What are the adverse effects common to the NRTIs?
1) Lactic acidosis
2) Fatty liver disease
3) Lipodystrophy
What does NNRTI stand for?

What is the MOA of the NNRTIs?
Binds to Reverse Transcriptase a site OTHER THAN THE ACTIVE SITE and inhibits the enzyme
What are the adverse effects common to the NNRTIs?
Hepatoxicity
Rash (StevensJohnson Syndrome)
Drug Interactions
What does PI stand for?
