Q

What is the mechanism for ACE inhibitors

A

Blocks endothelial ACE from converting angiotensin I to angiotensin II (potent vasoconstrictor); as a side effect, also prevents breakdown of bradykinin (potent vasodilator)

25

30

Decreased exercise tolerance, lethargy, insomnia,
33
What are the miscellaneous for Metoprolol, propranolol, bisoprolol

35
What is the mechanism for Nitrates
Endothelium independent vasodilator; endothelial effects (inhibits platelet aggregation, inhibits leukocyte-endothelial interactions (anti-inflammatory))
36

For acute episodes; long-acting formulations are for those already on other drugs and still can't control angina
37
What are the important side effects for Nitrates
Tolerance w/chronic use (need nitrate free periods of 8-12 hours), headaches, hypotension, activation of Bezold-Jarisch reflex (causes bradycardia)
38

Increase preload
39
What are the miscellaneous for Nitrates
Contraindicated in hypertrophic cardiomyopathy, severe aortic stenosis, significant hypotension, use of phosphodiesterase inhibitors
40
What is the class for Nefedipine (Procardia)
Calcium channel blockers (dihydropyridines, 1st generation)
41
What is the mechanism for Nefedipine (Procardia)
Interact with L-type voltage gated plasma membrane Ca channel --> decreased calcium entry into vascular smooth muscle cell, preventing contraction; causes dilation of epicardial coronary arteries, arteriolar resistance arteries; less heart-specific activity, but more than 1st generation

44
What are the other side effects for Nefedipine (Procardia)
Constipation (most common), headache, flushing
