Describe the Mechanisms of Ischemia

Describe the Clinical Utility of Vasodilators

What is the The “Steal Phenomenon”

What are the Vasodilator Mechanisms?
- Blockade of endogenous vasoconstrictors
- Direct relaxation of vascular smooth muscle
- Non-endothelium-dependent vasodilators
Describe the Blockade of endogenous vasoconstrictors

Describe the Direct relaxation of vascular smooth muscle

Describe the Non-endothelium-dependent vasodilators

Describe what Sodium Nitroprusside is used for

Describe what Nitroglycerin is what its MOA

Describe the PKs and ADRs of Nitroglycerin

Describe Isosorbide dinitrate

Describe Nifedipine

Describe Dipyridamole

What are the “Other Vasodilators”

Describe EDRF and Endothelin
● Endothelin has structural similarities to venom of the Israeli burrowing asp
○ Victims die of heart attack (likely due to severe vasoconstriction)
