Definition
inhibits Na+/K+ ATPase; stim vagus n.
toxicity -- blurry yellow vision, N/V/D, prolonged PR/decreased QT/scooping/T-wave inversion/arrhythmia/hyperK
worse with renal failure (less excretion), hypoK (less competition for ATPase), quinidine (competes for albumin)
Term
nesiritide
Definition
recombinant BNP --> increased cGMP --> vasodilation
Term
