Vasodilators

Question 1

Calcium channel blockers

Answer 1

• Prevents calcium from entering cell. Cell cannot contract the same–> relaxes/dilates
• Cardiac arrhythmias, HTN, angina

Question 2

Angiotensin Converting Enzyme (ACE) Inhibitors

Answer 2

• Decreases BP by reducing peripheral vascular resistance, w/o increasing CO output
• HTN
• Dry Cough

Question 3

Angiotensin Receptor Blockers (ARBs)

Answer 3

• Arterial/venous dilation. Blocks aldosterone secretion, therefore BP drops, but no H2O region
• HTN
