Along with beta blockers and digoxin, calcium channel blockers have one of the highest rates of death in overdose. [2] These medications first became available in the 1970s and 1980s. [ 2 ] They are one of the few types of medication in which one pill can result in the death of a child.
Side effects of these drugs may include but are not limited to: Constipation; Peripheral edema, which can occur in as much as 70% of people receiving calcium channel blocker, is caused by calcium channel blockers' preferential arteriolar or precapillary dilation without commensurate dilation in the venous or postcapillary circulation.
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. Amlodipine inhibits calcium ion influx across cell membranes, with a greater effect on vascular smooth ...
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.

As a medication it is used to treat low blood sugar, beta blocker overdose, calcium channel blocker overdose, and those with anaphylaxis who do not improve with epinephrine. [10] It is given by injection into a vein, muscle, or under the skin. [10] A version given in the nose is also available. [11] Common side effects include vomiting. [10]
Itraconazole also inhibits an important cytochrome liver enzyme (CYP 450 3A4) which is needed to metabolize isradipine and other calcium channel blockers. This will increase plasma levels of isradipine and could cause an unintentional overdose of the medication. Caution is advised when administering both agents together.
Administration of calcium channel blockers should be used with care in patients with renal disease and hypotension. Concomitant use of calcium channel blockers and magnesium sulfate may result in cardiovascular collapse [28] Calcium channel blockers have the fewest neonatal adverse effects [5] Atosiban: Oxytocin receptor antagonist
Chemically, it is based upon a 1,4-thiazepine ring, making it a benzothiazepine-type calcium channel blocker. It is a potent and mild vasodilator of coronary and peripheral vessels , respectively, [ 29 ] which reduces peripheral resistance and afterload , though not as potent as the dihydropyridine (DHP) calcium channel blockers.
