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.
Hypotension and reflex tachycardia are potential consequences of rapid upward titration of Cleviprex. In clinical trials, a similar increase in heart rate was observed in both Cleviprex and comparator arms. Dihydropyridine calcium channel blockers can produce negative inotropic effects and exacerbate heart failure. Heart failure patients should ...
The 8th Joint National Committee (JNC-8) recommends calcium channel blockers to be a first-line treatment either as monotherapy or in combination with thiazide-type diuretics, ACEis, or ARBs for all patients regardless of age or race. [7] The ratio of CCBs' anti-proteinuria effect, non-dihydropyridine to dihydropyridine was 30 to −2. [13]
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]
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. [2]
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 ...
Expected symptoms include severe hypotension (low blood pressure) and reflex tachycardia. Bradycardia (slow heartbeat) can also occur due to blockage of calcium channels in the atrioventricular node of the heart. There is no treatment besides monitoring blood pressure and heart function.
Calcium channel blocker poisoning, calcium channel blocker overdose: A 20% lipid emulsion commonly used for calcium channel blocker toxicity: Specialty: Emergency medicine: Symptoms: Slow heart rate, low blood pressure, nausea, vomiting, sleepiness [1] [2] Complications: Cardiac arrest [2] Usual onset: Within 6 hours [2] Causes: Too much ...
