Nonselective Beta-Adrenergic Blocking Agent (Alfa Beta Blocker)
(Propranolol) ✅Actions:
Competitively blocks receptors in heart
(= decreased HR contractility, excitability, membrane stabilization, decrease arrhyth.,
decrease heart workload, decrease O2 use) & in juxtaglomerular app. in nephron (no
renin released = further decrease in BP.
Indication:
*HTN, angina, migraine headaches
Re-infarction after MI's
Prevention of stage fright
Essential tremors
Nucleoside inhibitors
(Zidovudine) ✅Indication:
Combination HIV tx
Nucleoside inhibitors
(Zidovudine) ✅Action:
Competes w/naturally occurring nucleosides w/in cell that the virus needs to develop
and build DNA chain = No production *Can't build DNA chain!*
Nucleoside inhibitors
(Zidovudine) ✅Caution:
Hep/Renal dysfx
Bone marrow suppression
Contra:
No breast feeding!!
Nucleoside inhibitors
(Zidovudine) ✅Drug-Drug:
Alcohol
Some HIV meds
Antibiotic/Anti-fungal (Increase their effects!)
Nucleoside inhibitors
(Zidovudine) ✅Adverse Effects:
Hypersensitive rxn-fever*
Hepatomegaly
Bone marrow suppression
Nucleoside inhibitors
,(Zidovudine) ✅Nursing C's:
Safe if pregnant!
Reverse Transcriptase Inhibitors-non nucleoside
(Nevirapine, Abacavir, Viread) ✅Indications:
HIV/AIDs w/ARC w/ decreased # of helpter T cells and increased opportunistic
infections
Reverse Transcriptase Inhibitors-non nucleoside
(Nevirapine, Abacavir, Viread) ✅Action:
Binds directly to HIV recerse transc. = Blocks RNA & DNA dependent DNA polymerase
= *virus can't form viral DNA* & can't take over cell/reproduce

FLu-like symp. ( muscle aches/pains, faligue, appetite loss, fever
Protease Inhibitor
(Fasamprenavir) ✅Actions:
BLocks protease activity w/in HIV virus = *remains immature & non-infective (unable to
fuse w/and inject ifself into cells)*
Indication:
Part of combo therapy for HIV inf.
Reverse Transcriptase Inhibitors-non nucleoside
(Nevirapine, Abacavir, Viread) ✅Caution:
Hepatic dysfx
**saquinavir safe for lact**
, Contra:
No breast feeding!!
