Verapamil is a medication primarily used to treat high blood pressure and certain heart conditions, such as angina and arrhythmias. It belongs to a class of drugs known as calcium channel blockers, which work by relaxing the blood vessels and reducing the heart's workload. In addition to its cardiovascular uses, verapamil can also help prevent migraines and treat certain types of cluster headaches. It is available in various forms, including tablets and injections, and is typically prescribed by healthcare professionals based on individual patient needs.
