2.8 Aliskiren
Aliskiren is an orally active agent used in the treatment of hypertension. This non-peptide drug acts as an inhibitor
of renin, the enzyme that converts angiotensinogen (its endogenous substrate) to angiotensin I. Biologically inactive,
angiotensin I is rapidly converted to angiotensin II by angiotensin converting enzyme. Angiotensin II is a potent
agonist when bound to its receptor and produces significant vasoconstriction, as well as an increase in blood pressure.
In the presence of aliskiren, angiotensinogen is not converted to angiotensin I so less angiotensin II is produced to
activate the angiotensin II receptor. Consequently less vasoconstriction occurs, and a drop in blood pressure results.
