Used primarily in the treatment of hypertension (high blood pressure) and chronic stable angina, this compound helps relax blood vessels, allowing for smoother blood flow and reduced strain on the heart. It is also prescribed for patients with vasospastic angina (Prinzmetal's angina) to prevent coronary artery spasms. Due to its long half-life, it provides consistent blood pressure control with once-daily dosing, improving patient compliance. Often used in combination with other cardiovascular medications such as statins or beta-blockers, it plays a key role in managing overall cardiovascular risk.
