Medications
A
“-dipine”
- Amiodipine
- Felodipine
- Nifedipine
- Verapamil
- Diltiazem
2
Q
Action
A
- Inhibits the movement of calcium ions across the cell membranes of cardiac and arterial muscles, leading to slowed conduction, decreased myocardial contractility, and relaxing and dilating the arteries
- Decreases BP and cardiac work load
