Indanidine is primarily used in the field of pharmacology as an antihypertensive agent. It functions by targeting and modulating specific receptors in the body, which helps in lowering high blood pressure. This makes it a valuable component in the treatment of hypertension, aiding in the management of cardiovascular health. Additionally, its mechanism of action has been studied for potential applications in other conditions related to blood pressure regulation, though its primary use remains focused on hypertension control.
