Aliskiren is a first-in-class antihypertensive drug that acts by direct inhibition of renin. It is indicated for oral administration either as monotherapy or in combination with other antihypertensive agents. Renin catalyzes the cleavage of angiotensin to form angiotensin I, the first and the rate-limiting step of the RAAS. The inhibition of renin by aliskiren results in reduced levels of angiotensin I, angiotensin II, and aldosterone, all of which contribute to the antihypertensive effect. RAAS modulators are among some of the most commonly prescribed antihypertensive agents to date.
