Pharma-anti HIV drugs Flashcards
(34 cards)
Drug group that Competitively inhibits BINDING OF NATURAL nucleotides to rev transcriptase
Also acts as chain terminators
NRTI
T/F
NRTI lacks 5’- hydroxyl group
F.
3’
Resistance to NRTI due to
pol GENE MUTATION
Pancreatitis toxicity is dose limiting for this NRTI
Didanosine
Once daily dosing,
CI in preggies and young children due to propylene glycol content
Emtricitabine
anti HIV that is also effective vs HEPa B
Lamivudine
Lamivudine excreted almost exclusively by …
Kidney
NRTI with good tissue penetration with oral dosing, incl CNS
Stavudine
AE more frequently observed in Stavudine
Lactic acidosis with hepatic steatosis
a nucleotide NRTI also with HEpa B activity
Tenofovir
Tenofovir impede renal elimination of
Acyclovir
Ganciclovir
NRTi with periph neuropathy as dose limiting factor
Dr zialCITA, Nuero Proph~` ~ periph neuropatihy
zalCITAbine
This drug increases clearance of ZIDOVUDINE
Rifampin
This group of drug does not require phosphorylation to be activated
binds to site in Rev transc diff from NRTI
resistance due to
NNRTI
Pol gene mutation
Major problem is drug interaction,
CYP2D6, CYP3A4
Delavirdine
Once daily dosing NNRTI
toxicity include elevated serum cholesterol level
CI in 1st tri pregnancy
Efavirenz
For HIV resistant to other drug groups
Etravirine
Effective in preventing VIRtical transmission
given to mother once at labor and to neonate
neVIRapine
Nevirapine levels inc by
Cimetidine, Macrolides
Nevirapine levels dec by
Enzyme inducers
Dependent on ASPartate Protease (HIV-1 portease)
Protease inhibitors.
-navirs
PI given OD
Requires ACIDIC environment
Penetrates:: CSF, seminal fluid
biliary elimination
Atazanavir
T/F
Atazanavir associated with Dyslipidemia, fat deposition, metabolic syndrome
False.
Unlike most PIs
PI with propylene glycol, not for preggies or children
Fosamprenavir
