Iganidipine is primarily used in the management of hypertension, effectively lowering blood pressure by relaxing the blood vessels. It is also applied in treating angina pectoris, helping to reduce the frequency and severity of chest pain by improving blood flow to the heart. Additionally, it is sometimes utilized in renal protection strategies for patients with chronic kidney disease, as it helps to mitigate renal damage associated with high blood pressure. Its vasodilatory effects make it a valuable component in cardiovascular therapy.
