Chronic hypertension is a lifelong condition, and the patients need lifelong treatment with oral anti-hypertensive medications to say healthy and to prevent the development of serious complications. Demands for changing this situation of lifelong dependence on daily medications have been increasing. The aim of this paper is to highlight the recent breakthrough in hypertension research. Expert opinion: Zilebesiran, a small interfering RNA targeting angiotensinogen has the main advantage of long duration of action which allows meeting many hypertensions patients’ demand of avoiding the inconvenience of talking oral hypertensive medication on daily basis. It is worth mentioning that a more optimal blockade of renin-angiotensin-aldosterone system is not the only advantageous therapeutic approach for the treatment of hypertension. Impairment of endothelium-dependent vasodilation has been increasingly recognized as an important contributor for the development of essential hypertension’s-arginine is an amino acid that is considered the biological precursor of nitric oxide which is an important contributor to microvascular vasodilation and to the reduction atherosclerosis. Oral L-arginine has been emerging as a new effective approach of reducing blood through improving endothelial function in hypertensive patients.
