<div style="text-align: center;"> <img src="https://tse1.mm.bing.net/th?q=Amlodipine%20Medication" alt="Amlodipine"> </div>
Amlodipine is a calcium channel blocker, effectively used to manage high blood pressure, angina, and coronary artery disease. Here's a closer look:
- Class: Calcium Channel Blockers
- Available Forms: Tablets (2.5 mg, 5 mg, 10 mg)
- Common Brand Names: Norvasc, Istin
How Does Amlodipine Work?
Amlodipine works by:
- Reducing Calcium Entry: Preventing excessive calcium from entering the muscle cells of the heart and arteries, which relaxes and widens these vessels.
- Lowering Blood Pressure: By allowing blood to flow more easily, it reduces arterial pressure.
- Decreasing Heart's Workload: Reducing the heart's oxygen demand, making it suitable for angina treatment.
<p class="pro-note">๐ก Note: Always consult with a healthcare provider for personalized medical advice on using Amlodipine.</p>
