What is the mechanism of action for amlodipine?
Mechanism of action on blood pressure Amlodipine is considered a peripheral arterial vasodilator that exerts its action directly on vascular smooth muscle to lead to a reduction in peripheral vascular resistance, causing a decrease in blood pressure.
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.
What is the onset of action of amlodipine?
Onset of effect is gradual after oral administration which is due, in part, to an intermediate rate of drug absorption (peak plasma drug concentration occurs 6-8 h after dosing) and perhaps also to the physicochemical characteristics of the drug-cell membrane-receptor interaction.

Is Amlodipine a receptor blocker?
Amlodipine/valsartan (Exforge) is a new combination of antihypertensive agents that lower blood pressure via calcium channel blockade and angiotensin receptor antagonism.
How is amlodipine absorbed?
Thus, amlodipine undergoes gradual absorption from the gastro-intestinal tract and is widely distributed throughout body tissues. It is cleared only slowly by metabolism in the liver and so has a long elimination half-life, which makes it suitable for single daily dosing.
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.
Why is amlodipine an antagonist?
Amlodipine Besylate Amlodipine is an intrinsically long-acting, vasoselective dihydropyridine calcium antagonist that inhibits calcium ion influx across cell membranes selectively, with a greater effect on vascular smooth muscle cells than on cardiac muscle cells.
How does amlodipine excreted from the body?
Amlodipine is extensively metabolized by the liver to inactive metabolites with 10% of the parent compound. The plasma elimination half-life is about 35-50 hours and is consistent with once daily dosing. 60% of metabolites are excreted in the urine.
Is Amlodipine a vasodilator?
Amlodipine is a peripheral arterial vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure.
Is amlodipine an ARB or ACE?
Amlodipine relaxes (widens) blood vessels and improves blood flow. Benazepril is an ACE inhibitor. ACE stands for angiotensin converting enzyme….Similar Drugs.
