Categories of Calcium Channel Blockers
Calcium channel blockers (CCBs) are used to treat cardiovascular conditions such as cerebral vasospasm. They are primarily classified into dihydropyridines and non-dihydropyridines, each with distinct mechanisms of action.
Dihydropyridines
Amlodipine, a dihydropyridine, acts on blood vessel walls to relax and dilate them. It is effective in managing high blood pressure and angina.
Dihydropyridines dilate blood vessels, enhancing blood flow and reducing vascular pressure.
Non-Dihydropyridine Agents
Verapamil and Diltiazem are non-dihydropyridine calcium channel blockers that act on the heart and blood vessels, reducing heart rate and causing vasodilation.
This treatment manages irregular heartbeats and chest pain while safeguarding the heart and blood vessels.
| Calcium Channel Blocker Type | Common Drugs | Primary Effects | Clinical Uses |
|---|---|---|---|
| Dihydropyridines | Amlodipine | Vasodilation of vascular smooth muscle | Hypertension, Angina |
| Non-Dihydropyridines | Verapamil , Diltiazem | Reduced myocardial contractility and heart rate, vasodilation | Arrhythmias, Angina, Hypertension |
