The negative chronotropic effects of CCBs make them a commonly used class of agents in individuals with atrial fibrillation or flutter in whom control of the heart rate is generally a goal. Negative chronotropy can be beneficial when treating a variety of disease processes because lower heart rates represent lower cardiac oxygen requirements.
Amlodipine, sold under the brand name Norvasc among others, is a calcium channel blocker medication used to treat high blood pressure, coronary artery disease (CAD) [10] and variant angina (also called Prinzmetal angina or coronary artery vasospasm, among other names). [11]
However, it may be used to treat hypertension if patient has co-morbid atrial fibrillation or other types of arrhythmia. [17] [21] Verapamil is used intra-arterially to treat cerebral vasospasm. [22] It is also used to treat cluster headaches. [23] Tentative evidence supports the use of verapamil topically to treat plantar fibromatosis. [24]
Prevention of atrial fibrillation [ edit ] In 2005, meta-analysis results showed that angiotensin receptor blockers and angiotensin converting enzyme inhibitors considerably reduce the risk of atrial fibrillation in patients with coexisting heart failure and systolic left ventricular dysfunction.

Apixaban is recommended by the National Institute for Health and Clinical Excellence for the prevention of stroke and systemic embolism in people with non-valvular atrial fibrillation and at least one of the following risk factors: prior stroke or transient ischemic attack, age 75 years or older, diabetes, or symptomatic heart failure.
While Ozempic is FDA-approved to manage type 2 diabetes, Wegovy is a higher-dose version of the drug that is approved for weight loss, making it a good alternative to Ozempic if you were hoping to ...
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 ]
Dronedarone has been termed a "multichannel blocker". [citation needed] However, it is unclear which channel(s) play a pivotal role in its success. [9]Thus, dronedarone's actions at the cellular level are controversial, with most studies suggesting an inhibition in multiple outward potassium currents including rapid delayed rectifier, slow delayed rectifier and ACh-activated inward rectifier.
