Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists [2] are a group of medications that disrupt the movement of calcium (Ca 2+) through calcium channels. [3] Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension.
Age can affect the choice of medications. Current UK guidelines suggest starting patients over the age of 55 years first on calcium channel blockers or thiazide diuretics. Age and multi-morbidity can affect the choice of medication, the target blood pressure and even whether to treat or not. [61] Anxiety may be improved with the use of beta ...
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 ...
It is a calcium antagonist accompanied with L-type and N-type calcium channel blocking functions. Unlike other calcium antagonists, cilnidipine can act on the N-type calcium channel in addition to acting on the L-type calcium channel. It was patented in 1984 and approved for medical use in 1995.
While trying to conceive a child and during pregnancy, medical advice should be followed to optimize the management of the person's epilepsy in order to keep the person and the unborn baby safe from epileptic seizures and also ensure that the risk of birth defects due to in utero exposure of anticonvulsants is as low as possible.
Isradipine (tradenames DynaCirc, Prescal) is a calcium channel blocker of the dihydropyridine class. It is usually prescribed for the treatment of high blood pressure in order to reduce the risk of stroke and heart attack. It was patented in 1978 and approved for medical use in 1989. [1]
Diltiazem, sold under the brand name Cardizem among others, is a nondihydropyridine calcium channel blocker medication used to treat high blood pressure, angina, and certain heart arrhythmias. [9] It may also be used in hyperthyroidism if beta blockers cannot be used. [9] It is taken by mouth or given by injection into a vein. [9]
Although evidence shows calcium channel blockers and thiazide-type diuretics are preferred first-line treatments for most people (due to both efficacy and cost), an angiotensin II receptor antagonist such as losartan is recommended as first-line treatment in people under the age of 55 who cannot tolerate an ACE inhibitor.
