Used primarily as an anti-anginal agent to treat chronic stable angina by improving myocardial oxygen supply and reducing demand. It functions as a calcium channel blocker, helping to relax coronary arteries and improve blood flow to the heart muscle. Also exhibits antiarrhythmic properties, making it useful in managing certain cardiac rhythm disorders. Has been investigated for potential off-label uses in neurodegenerative conditions due to its ability to modulate cellular calcium levels and inhibit calmodulin activity. Additionally, studied for repurposing in cancer therapy because of its effects on autophagy and ion channel interference in tumor cells.
