Used primarily to treat high blood pressure (hypertension) and angina (chest pain), this chemical helps relax blood vessels, improving blood flow and reducing the workload on the heart. It is commonly prescribed as a long-acting medication, allowing for once-daily dosing, which supports better patient compliance. Often used alone or in combination with other antihypertensives, it plays a key role in reducing the risk of stroke, heart attack, and kidney problems in patients with cardiovascular conditions. Also beneficial in managing certain types of coronary artery disease.
