Test2: Wk8: 3 Inhibitors of the RAAS - Salisbury Flashcards
Function of RAAS
adaptive pathway that mediates Na and Water retention to restore BP during periods of decreased BP
ACEIs Mechanism
Prevent ATII formation ⬇ aldosterone ⬇ ATII vasoconstriction ⬇ neuronal release of NE ⬇ cardiac, vascular, glomerular remodeling ⬆ BK/PG ⬇ VC EA
ACEI effects
⬇ TPR ⬇ Na and H2O retention ⬆ K retention ⬇ BP ⬇ GFR
— have renoprotective effects
ACEIs
ANGII effects —, —, and, —
EA, Mesangial Cells, Mesangial Matrix
ACEI suffiix
pril
ACEIs are prodrugs except
captopril and lisinopril
Most ACEI are — eliminated
renal
ACEIs with hepatic and renal metabolism
Fosinopril
ACEIs uses
Hypertension
CHF
Post Mi
ACEIs renal protective effects
decrease intraglomerular pressure and prevent further damage
decrease mesangial proliferation, matric expansion and thickening of glomerular basement membrane
ACEIs adverse effects
Hypotension. Teratogen, Cough, Angioedema, Hyperkalemia, increase serum Creatine
ACEIs contraindications/ precautions
Pregnancy
Low renal Blood Flow
ACEIs compromise — contriction
EA
ACE inhibitors Contraindications/precautions
Hyperkalemia • K sparing diuretics • Non selective ꞵblockers • K supplements
Drug interactions with ACEIs
K sparing diuretics, K
supplements, non selective Beta blockers
(antagonism of ꞵ2 will ↓ K + uptake by skeletal
— may worsen ACEIs cough
Capsaicin
AT 1 Receptor antagonists suffix
-tan
ARBs inhibit
AT1 R
ACEIs are more likely to promote venodilation (preload) than ARBs because ACEIs increase
