Calcium channel blocker toxicity is the taking of too much of the medications known as calcium channel blockers (CCBs), either by accident or on purpose. [3] This often causes a slow heart rate and low blood pressure . [ 1 ]
It is a calcium channel blocker of the dihydropyridine type. [2] Nifedipine is taken by mouth and comes in fast- and slow-release formulations. [2] Common side effects include lightheadedness, headache, feeling tired, leg swelling, cough, and shortness of breath. [2] Serious side effects may include low blood pressure and heart failure. [2]
Amlodipine is a long-acting calcium channel antagonist that selectively inhibits calcium ion influx across cell membranes. [42] It targets L-type calcium channels in muscle cells and N-type calcium channels in the central nervous system which are involved in nociceptive signalling and pain perception.
Certain calcium channel blockers, such as diltiazem and verapamil, are known to decrease the force with which the heart ejects blood, thus are not recommended in people with heart failure with a reduced ejection fraction. [54] Breast cancer patients are at high risk of heart failure due to several factors. [55]
CCBs are particularly effective against large vessel stiffness, one of the common causes of elevated systolic blood pressure in elderly patients. [4] Calcium channel blockers are also frequently used to alter heart rate (especially from atrial fibrillation), to prevent peripheral and cerebral vasospasm, and to reduce chest pain caused by angina ...
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
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
Verapamil is also a Kv voltage gated potassium channel blocker. [37] Calcium channels are also present in the smooth muscle lining blood vessels. By relaxing the tone of this smooth muscle, calcium channel blockers dilate the blood vessels. This has led to their use in treating high blood pressure and angina pectoris. The pain of angina is ...
