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
