Aliskiren is an antagonist to renin.<ref name="a12">PMID:10903938</ref> Renin, the first enzyme in the renin–angiotensin–aldosterone system, plays a role in blood pressure control. It cleaves angiotensinogen to angiotensin I, which is in turn converted by angiotensin-converting enzyme (ACE) to angiotensin II. Angiotensin II has both direct and indirect effects on blood pressure. It directly causes arterial smooth muscle to contract, leading to vasoconstriction and increased blood pressure. Angiotensin II also stimulates the production of aldosterone from the adrenal cortex, which causes the tubules of the kidneys to increase reabsorption of sodium, with water following, thereby increasing plasma volume, and thus blood pressure.<ref name="a12">PMID:10903938</ref> | Aliskiren is an antagonist to renin.<ref name="a12">PMID:10903938</ref> Renin, the first enzyme in the renin–angiotensin–aldosterone system, plays a role in blood pressure control.

There are three generations of renin inhibitors. The first two generation molecules were peptide molecules. These peptide molecules were not specific or effective as renin inhibitors. Aliskiren, part of the 3<sup>rd</sup> generation, is a nonpeptide renin inhibitor. Small molecule nonpeptide inhibitors such as aliskiren have good pharmokenetics and are very specific for renin and not other protein peptidases. Advancements in crystallography and molecular modeling allowed the discovery of aliskiren. Aliskiren inhibits renin activity. Since renin is the rate limiting step of the RAS renin inhibition is a successful method to lower blood pressure. | There are three generations of renin inhibitors.
