Amlodipine besylate is a calcium channel blocker primarily used to treat hypertension and angina. It relaxes blood vessels, lowering blood pressure and improving blood flow to the heart.
Here’s what you should know:
- Mechanism of Action: Amlodipine inhibits the influx of calcium ions into vascular smooth muscle and cardiac muscle cells. This leads to vasodilation and decreased myocardial contractility. Dosage Forms: It’s available as tablets and extended-release tablets, allowing for once-daily dosing in many cases. Hypertension Treatment: Amlodipine effectively lowers both systolic and diastolic blood pressure. It often used in combination with other antihypertensive medications for optimal control. Angina Treatment: By improving blood flow to the heart, amlodipine reduces the frequency and severity of angina attacks. It’s particularly beneficial for patients with vasospastic angina (Prinzmetal’s angina).
Important considerations:
Side Effects: Common side effects include headache, dizziness, edema, and flushing. Rare but serious side effects include liver injury and allergic reactions. Consult a physician if you experience any concerning symptoms. Precautions: Amlodipine should be used cautiously in patients with liver disease, heart failure, or elderly patients. Grapefruit juice can interact with amlodipine, potentially increasing its blood levels and the risk of side effects. Avoid grapefruit juice while taking this medication. Drug Interactions: Amlodipine may interact with several medications, including other calcium channel blockers, beta-blockers, and certain statins. Always inform your doctor of all medications you are taking. Pregnancy and Breastfeeding: Consult your doctor before using amlodipine if you are pregnant or breastfeeding. The medication may pass into breast milk.
