E3: AntiVirals Flashcards
What are the 3 ways you can STOP a virus?
1.alter UNCOATING 2.Polymerase Inhibitors 3.Inhibit protein synthesis
What are the 2 most common indications for Interferons?
Hep B/C and MS
What does “HAART” therapy stand for?
Highly Active AntiRetroviral Therapy
Typical HAART cocktail: 3 types
- nucleoside reverse transcriptase inhibitor, 2.non-nucleoside reverse transcriptase inhibitor and 3. a protease inhibitor
Antiretrovirals are started for most HIV-infected patients when immunosuppression becomes pronounced….CD4 count less than _____
500
What is the HIV antiFungal?
Amphoteracin B. should be a reflex
nucleoside reverse transcriptase inhibitor, Must be biotransformed/________ to work
bioactivated
Reverse transcriptase of HIV is ____ times more susceptible to inhibition than are normal human cells
1100
Which Drugs have no effect on cells already containing HIV?
Nucleoside reverse transcriptase inhibitors
AZT/Retrovir is a(n)
Nucleoside reverse transcriptase inhibitor
Many oral effects: altered taste, tongue edema, bleeding gingiva, mouth ulcers
zidovudine (Retrovir) = “AZT”
Do not require bioactivation
NONnucleoside reverse transcriptase inhibitors
Drugs suppress viral replication by inhibiting _______, the enzyme responsible for cleaving viral precursor peptides into infective virions
protease
Inhibits ______, the enzyme that helps to insert the viral cDNA strand produced by reverse transcriptase into the human genome
integrase
Hiv can cause this term for “ring around the teeth”
linear gingival erythema
