Which of these drugs DO NOT decrease angiotensin Il activity 
Select and explain. 
A. Enalapril, B. Valsaan, C. Nesiritide, D. Omapatrilat
C: Nesiritide
Answer: C: Nesiritide 
Explanation: (Ref: Katzung 10/e p205, 286) ACE inhibitors and AT1, antagonists decrease angiotensin Il activity. Omapatrilat is a vasopeptidase inhibitor that acts by inhibiting two enzymes, ACE and NEP. As it inhibits ACE, it may also decrease angitotensin II activity. Nesiritide is a recombinant BNP and has no effect on angiotensin II activity.
