Mechanism & Pharmacology

Simplified explanation (patient-friendly)

Verapamil, categorized as a calcium channel blocker, serves a fundamental role in relaxing blood vessels while also reducing the heart rate. This pivotal action contributes to the management of high blood pressure and conditions such as angina and arrhythmias. Adhering to prescribed dosages is crucial for patients to achieve optimal results. Regular check-ins with healthcare professionals can help patients understand their treatment better, enabling adjustments when necessary for effective management.

Clinical terms (Health Canada approved monograph references)

In clinical terms, verapamil functions by inhibiting calcium ions from entering both cardiac and smooth muscle cells. This leads to decreased myocardial contractility and vasodilation.
