(P) DIGOXIN **
|
Txs CHF --> ENHANCES CARDIAC CONTRACTILITY
4: CHF (high HR, but 小ittle CO) atrial fibrillation (irregular QRS complexes on EKG) MECH: screws up Na+--K+--ATP-ase pump --> increases intracellular Ca++ --> slows down 心eart & squeezes more forcefully - RAPID ONSET 之f Fx - NARROW THERAPEUTIC INDEX --> monitor serum levels CONTRAS: 心eart block (no P 波aves) ventricular fibrillation ADVERSES: N & V & D, HeadA, anorexia & CNS Fx Dysrrhythmias (does bizarre things) - SNS slows down - 取AKE PULSE 持old med if HR<60 (since will 遅low the SNS) - get baseline K, Ca, Mg (hypoK = 危angerous) |

(P) NESIRITIDE
|
Txs CHF --> NATRIURETIC PEPTIDE
4: acute, decompensated HF - RAPID ONSET - MECH: Stimulates natriuretic peptide A/B receptors, promoting smooth 筋uscle cell relaxation & vasoDILATION (= decreases preload) CONTRAS: Cardiogenic shock, hypersensitivity & systolic 血lood 圧ressure <90 mm Hg ADVERSES: cardiac 側ide effects -只nly administer with constant cardiac monitoring |

NITROGLYCERIN
|
Txs CHF -->others
- vasodilates - dilates coronary 血lood 隻essels - also an explosive (causes syncope & pounding headA) |
