Used primarily in the treatment of high blood pressure (hypertension) and chronic stable angina, this compound helps relax blood vessels, improving blood flow and reducing the workload on the heart. It is also prescribed for patients with vasospastic angina (Prinzmetal's angina) to prevent chest pain caused by spasms in the coronary arteries. Due to its long duration of action, it allows for once-daily dosing, enhancing patient compliance. The maleate salt form improves solubility and bioavailability, making it effective in lower doses. It is often used alone or in combination with other cardiovascular medications such as statins or beta-blockers.
