What is the mechanism of action for Amlodipine?
Mechanism of Action Amlodipine is a dihydropyridine calcium antagonist (calcium ion antagonist or slow-channel blocker) that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle.
What is the MOA of calcium channel blockers?
They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze (contract) more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.
What is the pharmacodynamics of Amlodipine?
Amlodipine, a basic dihydropyridine derivative, inhibits the calcium influx through ‘slow’ channels in peripheral vascular and coronary smooth muscle cells, thus producing marked vasodilation in peripheral and coronary vascular beds.
Is Amlodipine an ACE inhibitor?
Amlodipine relaxes (widens) blood vessels and improves blood flow. Benazepril is an ACE inhibitor. ACE stands for angiotensin converting enzyme….Similar Drugs.

Does amlodipine cause vasodilation?
Dihydropyridines — The dihydropyridines, including nifedipine, isradipine, felodipine, nicardipine, nisoldipine, lacidipine, amlodipine, and levamlodipine are potent vasodilators that have little or no negative effect clinically upon cardiac contractility or conduction.
Is amlodipine a vasodilator?
Amlodipine (Norvasc) is a dihydropyridine calcium channel blocker (CCB). It has vasodilator effects without significant negative inotropic properties and has been used safely in patients with congestive heart failure.
Is amlodipine a Nondihydropyridine?
A calcium channel blocker used to treat hypertension and to manage chronic stable angina. A non-dihydropyridine calcium channel blocker used in the treatment of angina, arrhythmia, and hypertension.
What is the mechanism of action of telmisartan?
Mechanism of Action Telmisartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland.
Where is amlodipine metabolized?
Amlodipine is extensively metabolised in the liver (but there is no significant presystemic or first-pass metabolism) and is slowly cleared with a terminal elimination half-life of 40 to 50h. Volume of distribution is large (21 L/kg) and there is a high degree of protein binding (98%).
Is amlodipine an ARB inhibitor?
Amlodipine is an effective antianginal agent, whereas ARBs are not. However, amlodipine is not effective in the treatment of heart failure; ARBs may be useful in this setting. ARBs are also effective in preserving renal function and may provide some protection from restenosis in patients who have had a PCI.
Is amlodipine an ACE inhibitor or calcium channel blocker?
ACE Inhibitors and Calcium Channel Blockers
| Drug | Drug Description |
|---|---|
| Manidipine | A dihydropyridine calcium channel blocker used to treat hypertension. |
| Amlodipine | A calcium channel blocker used to treat hypertension and angina. |
| Enalapril | A prodrug of an ACE inhibitor used to treat hypertension and congestive heart failure. |
What is the mechanism of action of amlodipine?
Mechanism of Action of amlodipine In a normotensive person, vascular smooth muscle contraction initiates when calcium enters the cell via voltage-dependent L-type calcium channels. The calcium binds to intracellular calmodulin, which subsequently binds to and activates myosin light-chain kinase (MLCK).
What kind of calcium channel blocker is amlodipine?
Amlodipine is an angioselective calcium channel blocker and inhibits the movement of calcium ions into vascular smooth muscle cells and cardiac muscle cells which inhibits the contraction of cardiac muscle and vascular smooth muscle cells.
When was amlodipine first approved by the FDA?
Amlodipine, initially approved by the FDA in 1987, is a popular antihypertensive drug belonging to the group of drugs called dihydropyridine calcium channel blockers.
When to use amlodipine for chronic stable angina?
Chronic Stable Angina – Amlodipine is indicated for the symptomatic treatment of chronic stable angina. Amlodipine may be used alone or in combination with other antianginal agents.
